🔧 Component Overview

The DJI Agras T100 OEM Liquid Level Gauge Signal Cable is the OEM liquid level gauge signal cable serving the spray tank and its covers, sensors, and connectors of the DJI Agras T100, with the exact length, connectors, and sealing the factory routing calls for.

Sealing, venting, and metering the liquid payload at the tank is the job description for the spray tank and its covers, sensors, and connectors, and this component is part of how it gets done. The T100 is a working machine — it earns its keep in fill-and-fly cycles, not hangar hours — and every component in the spray tank and its covers, sensors, and connectors is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Aluminum Clip, Spray Tank Lanyard, Spray Tank Cover Waterproof Permeability Cover.

Ignore a failing liquid level gauge signal cable and the bill compounds: downtime in the middle of an application window, collateral wear on the parts around it, and jobs that slip to a competitor while the aircraft sits. Replacing it costs a part; not replacing it costs acres. That trade only runs one direction.

For professional farmers, aerial applicators, and commercial drone operators, this component is how the spray tank and its covers, sensors, and connectors stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The T100 works brutally hard for its living, including:

• Sealing, venting, and metering the liquid payload at the tank
• Dawn-to-dusk spray campaigns during narrow application windows
• Repeated fill-fly-return cycles with minutes on the ground between loads
• Full-payload takeoffs from field edges, dozens of times per day
• Chemical exposure from fungicides, herbicides, insecticides, and foliar fertilizers
• Pressure-washer rinse-downs at the end of every spray day
• Vibration from eight propulsion motors running at working power
• Transport bouncing on trailers and truck beds between fields
• Temperature swings from cold morning starts to full-sun afternoons

What attacks this component in the field:

• Flex cycles at every arm fold and unfold
• Vibration abrading jackets at contact points
• Washdown water working at connector seals
• Chemical mist corroding exposed terminals
• UV embrittling the outer jacket
• Strain from routing tension after field repairs
• Connector fretting from maintenance cycles
• Heat from adjacent power electronics

That duty cycle is exactly what retires this component. None of these stresses is dramatic on its own — the accumulation is what does it. This is why wiring harnesses are inspection items every time the spray tank and its covers, sensors, and connectors is opened up, and why operators who run hard keep spares on the shelf.

A healthy liquid level gauge signal cable delivers:

• Factory-correct fit in the spray tank and its covers, sensors, and connectors — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored performance you can verify on the first post-repair flight
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Stock the liquid level gauge signal cable before the season does its work, and the spray tank and its covers, sensors, and connectors never becomes the reason the aircraft sits.

This is a low-current signal run, so it fails differently from a power cable and you diagnose it differently. A bad joint here does not get hot and does not trip anything. It adds resistance or lets water bridge two contacts, and what you see is a level number that is plausible but wrong, or a sensor that disappears from the app for a few seconds at a time. Judge this cable by what the reading does, not by whether anything smells warm or looks scorched.

Do the wiggle test with the tank part full and the app open where you can see the level. Working from the gauge end toward the aircraft, flex the cable in short sections and work each connector gently side to side while you watch the number. A reading that twitches, drops out, or jumps as you reach one particular spot has told you where the fault is to within a couple of inches. If the reading is rock steady no matter what you do to the harness, the cable is not your intermittent.

Water in a connector is the most common finding on this part and it fakes a sensor fault convincingly. Unplug both ends, look into the housings with a light for beads, a tide line, or green and white deposits, then dry them thoroughly and reconnect without changing anything else. A fault that goes away after drying and comes back after the next washdown is a sealing failure at that connector, and the cable, its boot, or the mating half is what needs replacing rather than the gauge.

Rule the gauge in or out before you order the cable. With power off, disconnect the cable at the gauge and check each conductor end to end, then check every conductor against every other one. Continuity end to end and no path between conductors means the harness is intact and the fault is upstream or downstream of it. Any conductor that reads open, or any pair that reads connected to each other, is a failed cable and no amount of work on the gauge or in the app will fix the reading.

⚙️ Functional Purpose

The liquid level gauge signal cable is designed to do one job in the spray tank and its covers, sensors, and connectors and do it to specification: sealing, venting, and metering the liquid payload at the tank.

The component:

• Serves the spray tank and its covers, sensors, and connectors of the DJI Agras T100 exactly as the factory intends
• Supports sealing, venting, and metering the liquid payload at the tank
• Maintains the tolerances and interfaces the surrounding parts depend on
• Withstands the chemical, vibration, and washdown environment of agricultural work
• Preserves the sealing and protection strategy of the platform
• Keeps failure modes visible and diagnosable instead of mysterious
• Restores factory behavior immediately upon correct installation
• Protects the more expensive components it works alongside
• Carries the exact DJI specification for its position
• Supports safe, predictable operation under full payload
• Eliminates the guesswork of near-fit substitutes
• Keeps the aircraft inside its designed maintenance program
• Holds up across a full season of professional duty

Function on the T100 is a chain: spray system performance depends on the spray tank and its covers, sensors, and connectors, and the spray tank and its covers, sensors, and connectors depends on every part in it holding specification. This component is one link in that chain — and chains fail at the worn link, not the average one.

That is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure. The operators with the best uptime records are not the ones with the newest aircraft — they are the ones who replace parts like this when inspection says so, on their own schedule instead of the failure's.

A failing liquid level gauge signal cable costs you:

• Downtime in the middle of an application window — the most expensive hours in agriculture
• Acres not covered while the aircraft waits on a part
• Collateral wear on the components around the failing one
• Diagnostic hours chasing symptoms instead of causes
• Rework when a temporary fix lets go mid-job
• Customer trust when scheduled work slips
• Higher repair bills the longer the fault runs
• Risk exposure every flight the fault remains aboard
• Resale value on an airframe with deferred maintenance

Fix it on your schedule, not the failure's.

Get the tank out of the way before you start. Drain it, flush with clean water, run the rinse through the system, and vent it, because this cable lives where product collects and you will have your hands and your face close to fittings that have been sitting in tank mix. Pull the batteries so nothing is live while connectors are open, and photograph the whole run before you disturb it, including every tie, clip, and pass-through and the exact place the cable enters and leaves any cover.

Release the connectors properly rather than quickly. These are small signal housings with fine terminals, and they punish impatience. Find and lift the latch fully, then pull on the connector body straight out, never on the wire and never at an angle. A terminal that has been dragged partway back in its housing will still make contact on the bench, pass every test you run in the shop, and then drop the level reading the first time the aircraft hits rough air with a full tank.

Route it back the way it came off, and give water somewhere to go. Reproduce the original path, the original tie points, and the original amount of slack. Where the design allows it, keep the low point of the run below the connector so water tracks away from the housing instead of collecting in it. Keep the cable off tank strap edges, fastener heads, and anything that moves, and keep it clear of the fill opening so it does not get soaked from above at every load.

Seat, seal, and then prove it with liquid. Push each connector until the latch is fully home and the faces meet square, check any boot or grommet is seated in its groove rather than rolled, and confirm the strain relief is supported by the clip rather than by the terminals. Then fill with clean water and watch the level reading at rest, on the move, and after a washdown, because a signal joint that is going to fail on moisture will not tell you anything on a dry bench.

⚠️ Common Replacement Indicators

• Intermittent faults that move with cable flex
• Errors after arm fold or unfold
• Chafed, cut, or abraded jacket
• Corroded, bent, or discolored connector pins
• Function dropouts under vibration
• Water or chemical residue inside connector shells
• Stiff, cracked jacket from UV or chemical exposure
• Failures that clear when the connector is wiggled
• Pinched or crushed sections from previous repairs
• Melted or discolored jacket near power electronics
• Faults after a hard landing pulled routing tight
• Continuity that fails only under load

What kills wiring harnesses: the compounding of ordinary duty. Chemical exposure attacks materials, vibration works at every interface, UV ages every exposed surface, and washdowns drive water at every seam — repeated across hundreds of cycles per season. Add the occasional hard landing or transport knock and the result is predictable: the part that was fine in spring is the failure point by late season.

Replacement and verification: Replacement is a standard shop task on the T100: open access to the spray tank and its covers, sensors, and connectors, document connections and hardware positions, swap the liquid level gauge signal cable for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.

Confirm before you order: this is DJI part YC.XC.XX001398. Check the label on your old liquid level gauge signal cable or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.

A level display that reads zero, reads full, or shows no value at all while the tank obviously contains something is a connection that has opened or shorted rather than a sensor that has drifted. Drift makes numbers wrong; a broken conductor or a bridged pair makes numbers meaningless. Start at the connectors and at any point in the run where the jacket has been rubbing.

A level value that jumps around during flight and settles when the aircraft is parked is movement finding a marginal joint. Vibration and a sloshing load flex the harness and rock the connectors, and a terminal that is loose in its housing or a conductor that is broken but still touching will make and break contact exactly in those conditions. That pattern points at the harness far more often than at the gauge.

Readings that go wrong right after every washdown and improve as the aircraft dries out are a sealing failure, not a calibration problem. Moisture across two contacts creates a path that was never meant to be there, and on a signal circuit that shows up as an offset or a nonsense value rather than as anything dramatic. Look for a compromised boot, a cracked or hardened seal, or a jacket that has been cut somewhere water can enter and wick along inside.

A jacket that has gone stiff, swollen, sticky, or discolored where it sits closest to the tank and its fittings is chemical attack, and it matters more here than on a cable in clean air. Once the outer layer is compromised, product and rinse water wick along inside the cable toward the connector, where they corrode terminals from the back side. The cable can look acceptable at both ends while the damage travels along the middle.

📐 Specifications

DJI Material Number: YC.XC.XX001398

Part: Liquid Level Gauge Signal Cable

Type: OEM cable / wiring harness with factory connectors

Compatibility:

• DJI Agras T100
• Position: the spray tank and its covers, sensors, and connectors
• Diagram sheet: Spray Tank 2 (official T100 parts list)

Quantity: 1

Installation Area: The spray tank and its covers, sensors, and connectors

Function: Sealing, venting, and metering the liquid payload at the tank

Construction: DJI OEM harness with factory connectors, jacketing, and sealing for its exact route

Application: DJI Agras T100 spray system service and repair

Condition: Brand new

Conductor Count, Gauge, Length, and Connector Type: Not published in this listing. Signal harnesses in the tank area share connector families and differ in pin count, keying, and run length, so ordering from a photograph or from a measurement of the old cable is unreliable. Match DJI material number YC.XC.XX001398 to the label on the harness you removed or to the callout on your T100 parts breakdown, and compare the two cables side by side before fitting.

Continuity and Insulation Values: Not published here, and comparison is the useful test anyway. Every conductor should read continuous end to end, and every conductor should read open against every other conductor and against any shield or drain. On a signal cable in a wet, chemical environment, a low but measurable path between two conductors is as much a failure as an open circuit, because it puts an offset into the reading without breaking anything outright.

Supplied Contents: The Package Includes list on this listing names the cable and OEM protective packaging. The liquid level gauge itself, connector boots and seals, grommets, clips, and cable ties are not listed among the contents. Since the tank area has to be opened and drained to reach this run, inspect those items while you have access and order them separately if they are hardened, torn, or missing.

🚜 Necessary For

Built for:

• Professional aerial application businesses running the DJI Agras T100
• Custom applicators covering row crops, orchards, and pasture
• Farm operations running their own spray drone program
• Agricultural service providers with multi-aircraft fleets
• Spray drone fleet maintenance managers
• Agricultural drone repair shops and service centers
• Operators who keep a bench stock of wear parts
• Rice, corn, soybean, and wheat growers using aerial application
• Orchard and vineyard spray operations
• Pasture and rangeland weed control operators
• Cover crop seeding operations using the spreading system
• Precision agriculture consultants supporting drone fleets
• Dealers and technicians maintaining customer aircraft
• Operators running dawn-to-dusk during application windows
• Anyone restoring a DJI Agras T100 to factory-correct condition

Especially valuable during:

• Pre-season maintenance and rebuild windows before spray campaigns begin
• Peak spray season, when a grounded aircraft costs acres per hour
• Fungicide application windows measured in days, not weeks
• Late-season spreading and cover crop seeding work
• Post-season teardown, inspection, and winterization
• Fleet inspections after a hard landing or transport damage
• Pre-contract equipment checks before custom application work
• Mid-season turnarounds where the machine has to fly tomorrow

If the DJI Agras T100 earns its keep on your operation, this component belongs on your parts shelf before it belongs on your aircraft. The time to buy it is before the season, not during the failure.

The tank area carries several thin harnesses that look alike in a diagram, and only one of them is this cable. Pump, flow meter, valve, and level gauge leads all use small housings and fine conductors, and they differ mainly in pin count, keying, and length. Count the pins in the housing on the part you removed and compare the run length, rather than deciding from the illustration. This listing is DJI material number YC.XC.XX001398 for the T100.

Do not confuse this cable with a gauge that has its own lead attached. On assemblies where the sensor and its wire are one part, there is no separate cable to order and replacing this item will not help. Look at what the connector at the sensor end plugs into: a plug that mates to a fixed socket on the gauge body means a separate harness, and a wire that disappears permanently into the sensor means the whole gauge is the part you need.

Bench-compare before fitting. Lay the new cable beside the old one, line up one connector, and check overall length, the position of any branch, where the clips or ties fall, and the keying and pin count at both housings. Near-fit signal cables exist across the Agras range, and a cable that is close will latch and then sit under tension or with slack in the wrong place, which is how a brand new harness ends up chafing or pulling on a terminal.

💡 Why This Part Matters

Every acre the T100 covers depends on the spray tank and its covers, sensors, and connectors doing its job — and the spray tank and its covers, sensors, and connectors depends on parts exactly like this one.

The economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed liquid level gauge signal cable is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.

That is the case for OEM and the case for stocking ahead. The OEM component fits the first time, behaves the way the platform expects, and carries the exact specification the spray system was engineered around — DJI material number YC.XC.XX001398. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the spray tank and its covers, sensors, and connectors — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored performance you can verify on the first post-repair flight
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Running a compromised liquid level gauge signal cable, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Chasing intermittent symptoms across the whole system
• Coverage quality the customer can see in the field
• Unplanned grounding with the fleet committed to jobs
• Warranty and service complications from improvised fixes
• Higher lifetime cost from deferred maintenance
• An aircraft that cannot be trusted at full payload

Route it right. Seat it fully. Seal it down. Keep the signal clean.

Ares Acres stocks the liquid level gauge signal cable in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

While you have the tank area open, look at everything that shares this environment. Inspect the mating connector on the aircraft side for the same corrosion you found on the cable, since a fresh terminal against a corroded one rebuilds the fault. Check the gauge body and its mount, the sealing element at the gauge, any grommet the cable passes through, and the clips that hold the run. Look for the polished band on the jacket that shows the cable has been moving against something, and follow it to whatever it was rubbing on.

The things that kill this cable are specific to where it lives. Product and rinse water pooling in an upward-facing connector, spray and drift landing on the run every working day, a jacket nicked during an unrelated tank job and then wicking chemistry along inside, tension introduced when someone reassembled a cover without restoring the original slack, and sunlight on the top of the tank all take life out of it. Find which one it was, or the replacement follows the original.

Handle and store it as the delicate part it is. Keep the new cable in wide coils rather than folded, never use it as a handle when repositioning the gauge or a cover, and keep concentrate and solvents off the jacket. Replace preventively rather than optimistically: a jacket that is cut, swollen, or hardened is finished even if it currently reads correctly, and a connector you have found full of water once will fill again. Level accuracy feeds decisions made in the air, so a marginal harness here is not worth carrying through a season.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 Liquid Level Gauge Signal Cable? It is the OEM liquid level gauge signal cable serving the spray tank and its covers, sensors, and connectors of the DJI Agras T100. It is the genuine DJI Agras component for this position, supplied new.

What is the DJI material number (part number) for the Liquid Level Gauge Signal Cable? The DJI material number is YC.XC.XX001398, listed on the official DJI Agras T100 parts breakdown. Labels sometimes carry a revision suffix such as .01 or .F — that is the same part; match the base number.

Which DJI Agras models does this component fit? Supplier-listed fitment is DJI Agras T100. Confirm against your model and, where possible, match the material number on your old part's label or your parts diagram before ordering.

How do I know my liquid level gauge signal cable needs replacing? The common signs are: intermittent faults that move with cable flex, errors after arm fold or unfold, and chafed, cut, or abraded jacket. Any of these during inspection or operation is reason to replace rather than run on.

What causes this component to fail? Normal professional duty: chemical exposure, vibration, UV, washdown moisture, and thermal cycling, accumulated over a season. Hard landings and transport knocks accelerate all of it.

How do I confirm the diagnosis before ordering? Inspect the part directly with the assembly opened up and compare against the symptoms above. Match the label on the old part to material number YC.XC.XX001398 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.

What does installation and verification look like? Replacement is a standard shop task on the T100: open access to the spray tank and its covers, sensors, and connectors, document connections and hardware positions, swap the liquid level gauge signal cable for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.

What other parts should I inspect at the same time? On the official diagram this part sits alongside Aluminum Clip, Spray Tank Lanyard, Spray Tank Cover Waterproof Permeability Cover. If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

The app says the level sensor is not detected. Is that the cable or the gauge?

It can be either, and the harness is the cheaper thing to rule out first. With power off, unplug the cable at both ends and check each conductor end to end and every conductor against every other. If every conductor is continuous and none are connected to each other, the cable is electrically sound and you should look at the gauge and at the aircraft-side connector. If anything reads open or bridged, the cable is the fault, and water sitting in a housing is the most common cause of a bridge.

My level reading is consistently off by a fixed amount rather than jumping around. Can a cable do that?

Yes, and it is one of the harder faults to accept. Added resistance from corroded terminals, or a small leakage path between conductors caused by moisture or contamination inside a housing, biases a signal instead of breaking it, so the aircraft reports a number that looks reasonable and is wrong by a consistent margin. Inspect and dry both connectors, then compare the reading before and after. A fixed offset that changes when you clean a connector was never a calibration problem.

Can I splice or solder a damaged section of this cable rather than replacing it?

It is a poor trade on a signal run in a wet, chemical environment. A splice introduces two new joints and a stiff section exactly where the harness needs to stay sealed and flexible, and product wicks into repaired insulation far more easily than into a factory jacket. The failures that follow are intermittent and offset-type, which is the most time-consuming kind of fault to chase in a field. Replace the run and keep the old one only long enough to compare against the new part.

Everything tests fine in the shop but the level goes wrong in flight. What should I check?

Reproduce the conditions rather than the test. In flight the harness is vibrating, the load is sloshing, and any moisture in a housing is being moved around. On the ground, put water in the tank, open the app, and flex the cable and work each connector by hand while watching the reading, then rock the aircraft to load the tank against its mounts. If the number reacts to any of that, you have found it. Also dry both connectors and see whether the behavior changes after the next washdown.
