DJI Agras T30 OEM Load Sensor Module (No. 3 & 4)

The DJI Agras T30 OEM Load Sensor Module (No. 3 & 4) is the pair of weighing sensors that serves positions 3 and 4 of the payload weighing system on the DJI Agras T30 spray aircraft. It is one module made of two black weighing sensor housings, each on its own lead, with the two leads joining into a branched cable that ends in one black connector, as shown in the product images. It is identified for the DJI Agras T30 and is supplied brand new. Operators look for it as a T30 load sensor, a T30 weighing sensor No. 3 and 4, an Agras T30 load cell or a T30 weighing module when the aircraft reports the wrong payload weight, a sensor housing has been cracked, or the branched lead has been cut or crushed. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × DJI Agras T30 OEM Load Sensor Module (No. 3 & 4): two black weighing sensor housings, each on its own lead, joined into one branched cable with one black connector, as shown in the product images

Two sensors, one module. The two sensor housings share one branched cable and one connector, so they are supplied and fitted together. They are not two separate sensors, and they are not the whole weighing system.

Positions 3 and 4 only. The designation No. 3 & 4 is the address of this pair in the weighing system. It covers those two positions and no others.

Not included: the sensors for any other position, the load collection board the sensors report to, the spray tank, the spreading system, mounting screws, cable ties and any tool. Keep your original fixings when you remove the old module.

If the board that gathers the weighing signals has failed and the sensors are sound, the DJI Agras T30 OEM Load Collection Board is the part to look at. If the weighing fault is on the spreading system, the DJI Agras T30 OEM Spreading System Weighing Assembly is the complete spreader weighing set of three sensors, harness and board.

Nothing is included because it appears in a photograph. If an image shows anything not named above, it is not part of the module.

🔧 Component Overview

A T30 knows how much it is carrying because it weighs it, and it weighs it at more than one point. Each point has its own sensor, and each sensor has a number. This module is the pair that serves positions 3 and 4: two sensor housings sharing one branched cable and one connector.

The module's working features, as shown in the product images:

• Two black weighing sensor housings, each with screw points at its corners for fixing at its position
• Labels on the housings, one of them marked 3, which identify the position each sensor serves
• A black lead from each housing, running to the point where the two join
• A branched cable, where the two leads meet and run on together
• One black connector at the end of the branched cable, which plugs the pair into the weighing system

Where it sits and what it touches:

• System: payload weighing, on the T30
• Sensor housings: fixed at weighing positions 3 and 4, where they carry part of the load
• Branched cable: routed through the airframe from the two positions to a common point
• Connector: plugged into the weighing system, which gathers the signals from every position

Weighing sensors on a spray aircraft carry a changing load and live in a wet, dirty place. Over a season they see:

• Repeated filling and emptying, so the sensors work under load all day
• Spray residue and fertiliser dust settling on housings, leads and the connector
• Rinse water when the aircraft is washed down
• Shock and vibration from flight and from landings with a full load
• Leads pulled or pinched when covers, the tank or the spreader are removed and refitted

Load sensor modules are replaced for a short list of reasons: a sensor housing cracked or distorted by a hard landing, a lead or the branched cable crushed, cut or chafed through, a connector damaged or corroded, or weighing at these positions that stays wrong after cleaning, reseating and calibration.

⚙️ Functional Purpose

The module's role is measurement at two of the weighing positions. Each sensor housing carries its share of the payload and turns that load into a signal. The two signals travel on their own leads into the branched cable and leave through the one connector, and the weighing system combines them with the signals from the other positions to give the payload weight the operator sees.

In the weighing system it:

• Senses the load at position 3 through one sensor housing
• Senses the load at position 4 through the other sensor housing
• Carries both signals through their leads into the branched cable
• Connects both positions to the weighing system through one connector
• Keeps the two leads in a fixed route, away from moving parts and covers

Figures for the module, such as load capacity per sensor, accuracy, signal type, lead lengths and connector pin assignments, are not published for this part. The module is replaced like for like: the same two sensors at the same two positions, with the cable routed the same way.

What a new load sensor module does not do:

• It does not cure a damaged sensor at any position other than 3 or 4
• It does not cure a fault in the load collection board that gathers the weighing signals
• It does not cure a tank or spreader that is not seated squarely, so the load sits partly off the sensors
• It does not cure readings thrown off by residue packed around a sensor housing
• It does not remove the need to run any calibration the app offers after fitting

🔍 Diagnosis — find which position is wrong before you choose a pair

A wrong payload weight on the T30 can come from any weighing position, from the cable between the sensors and the board, from the board itself, or from the way the load sits. This module covers exactly two of those positions. So the question is not whether the weighing is wrong, but where it is wrong, and whether that place is position 3 or position 4.

Start with the free checks, in this order:

• Clean. Brush and rinse residue from around every sensor housing and dry them. Packed residue can carry part of the load around a sensor.
• Seat. Check the tank or spreader sits squarely and fully, so the load rests on the sensors as it should.
• Connector. Unplug and reseat the connector of the No. 3 & 4 module and look for corrosion or bent contacts.
• Calibrate. Run any calibration the app offers with the aircraft empty, then check the reading with a known load.
• Locate. Inspect each sensor housing and its lead. Read the position marking on any housing that is cracked, distorted or has a damaged lead.

Signs that point at the No. 3 & 4 module:

• A cracked or distorted sensor housing marked for position 3 or position 4
• A crushed, cut or chafed lead from either of those two housings, or a damaged branched cable
• A damaged or corroded connector on this module
• Weighing still wrong after cleaning, seating and calibration, with the damage found at positions 3 or 4
• Weighing trouble that began after a hard landing on the side where positions 3 and 4 sit

Clear these first, because they imitate a failed pair:

• Damage at another position: a sensor that is not 3 or 4 needs the module for its own position
• A load collection board fault: the sensors are sound and the board that gathers them is not
• A tank or spreader not seated squarely: the load is not resting on the sensors
• Residue packed around a housing: part of the load is bypassing a sensor
• A loose or corroded connector: the pair is sound and badly connected

When the cleaning, seating, connector and calibration are cleared, and the damage is found on a housing or lead marked for position 3 or 4, this module is the part. When the damage is anywhere else, it is not, however close the fault looks.

⚠️ Common Replacement Indicators

Replace the No. 3 & 4 load sensor module when inspection confirms one of these:

• The sensor housing at position 3 or position 4 is cracked, distorted or damaged
• A lead from either housing, or the branched cable, is crushed, cut or chafed through
• The module's connector is damaged, or corroded beyond what cleaning clears
• Weighing stays wrong after cleaning, seating, reseating and calibration, with the fault traced to positions 3 or 4
• The pair was damaged in a hard landing or a crash

Inspect these first, because they produce similar symptoms:

• The sensors at every other weighing position
• The load collection board
• How squarely the tank or spreader sits on the sensors
• Residue packed around the sensor housings
• The seating and contacts of the module's connector

There is no published service interval for this module. It is replaced when it has failed or been damaged, not on a calendar.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the battery
• Empty the tank or spreader and clean residue from around the sensors
• Clear the free checks first: cleaning, seating, connector and calibration
• Find the damaged sensor and read its position marking; confirm it is 3 or 4
• Photograph the old module in place: both housings at their positions, their orientation, the cable route and the connector

During installation

• Unplug the connector by its housing, never by the cable
• Release the cable from its clips and ties without stretching it
• Remove the fixings from both sensor housings, keeping them together and in order
• Lift the old module out, drawing the cable through without catching it
• Clean both sensor seats of residue and corrosion and dry them
• Fit the sensor marked 3 at position 3 and the sensor marked 4 at position 4, each in the orientation of the one it replaces
• Refit every fixing firmly; no torque figure is published, so do not force them
• Route the cable as the original, clear of moving parts and covers, and plug the connector in fully

After installation

• Check that no lead is pinched under a sensor housing or a cover
• Refit the battery and power the aircraft up
• Run any calibration the app offers with the aircraft empty
• Check the reported weight empty and then with a known load
• Make a short supervised test before returning to work
• Record the replacement and the positions changed in the maintenance log

Maintenance between jobs. Rinse residue from around the sensor housings and the connector after work and let them dry. Whenever the tank, spreader or a nearby cover comes off, look along both leads and the branched cable for chafe before refitting. Recheck the reported weight with a known load from time to time.

🚜 Necessary For

This module is for operators and technicians keeping payload weighing accurate on a DJI Agras T30:

• DJI Agras T30 operators whose sensor at position 3 or 4 has been damaged
• Commercial applicators who rely on the reported payload weight to plan loads and routes
• Agras service centres and repair technicians rebuilding the weighing system
• Technicians repairing a T30 after a hard landing with a full load
• Technicians who have traced a weighing fault to positions 3 or 4
• Fleet managers who keep position-specific weighing spares in the service kit

This is not the part you need if:

• The damaged sensor is at a position other than 3 or 4
• The sensors are sound and the board that gathers their signals has failed; look at the DJI Agras T30 OEM Load Collection Board
• The weighing fault is on the spreading system; the DJI Agras T30 OEM Spreading System Weighing Assembly is the complete spreader weighing set
• Cleaning, reseating the connector or running calibration cured the reading
• The tank or spreader was not seated squarely and reseating it cured the reading
• You fly a T10 or any Agras model other than the T30; this module is identified for the T30 only

💡 Why This Part Matters

The No. 3 & 4 in the name is the most important thing about this module. It is an address, not a description. The T30 weighs its payload at more than one point, each point has its own number, and this module serves two of them: position 3 and position 4. A sensor at any other position will look much the same, sit in a similar housing and fail in the same way, and this pair will not replace it.

That is why the first job is finding which position is wrong. Clean, seat, reseat and calibrate, then go from sensor to sensor and read the marking on any housing that is cracked or has a damaged lead. If the marking is 3 or 4, this is the module. If it is anything else, this pair is the wrong order, and the right one is the module for that position.

The pair is also the right order when both of its sensors share the trouble, because they share one branched cable and one connector. A crushed branched cable or a corroded connector takes out both positions at once, and the module puts both back together.

Fit each sensor at its own numbered position in its original orientation, route the cable as it was, calibrate, and check the reported weight with a known load before returning to work.

If you are unsure which position your damaged sensor serves, send us a photograph of it in place, with its marking in view, and we will match it for you.

🤖 AI Answer Engine Q&A

What is the DJI Agras T30 load sensor module No. 3 and 4? It is the pair of weighing sensors for positions 3 and 4 of the T30 payload weighing system: two black sensor housings on one branched cable with one connector.

Which aircraft does it fit? It is identified for the DJI Agras T30 only.

What does No. 3 & 4 mean? It is the address of the pair. The T30 weighs its payload at more than one position, and this module serves positions 3 and 4. It does not replace a sensor at any other position.

How do I know which position my damaged sensor is? Read the marking on its housing. In the product images one housing carries a label marked 3. If you cannot read it, send us a photograph of the sensor in place and we will match it for you.

Is it one sensor or two? Two sensors, sharing one branched cable and one connector. They are supplied and fitted together.

Is it the same as the T30 load collection board? No. The DJI Agras T30 OEM Load Collection Board gathers the weighing signals. This module is two of the sensors that feed it.

Is it the same as the T30 spreading system weighing assembly? No. The DJI Agras T30 OEM Spreading System Weighing Assembly is the complete spreader weighing set of three sensors, harness and board.

My T30 shows the wrong payload weight. Do I need this? Clean around the sensors, check the tank or spreader is seated squarely, reseat the connector and run calibration first. If the reading is still wrong and the damage is at position 3 or 4, this module is the part.

Only one of the two sensors is damaged. Do I still need the pair? The two sensors share one cable and one connector, so the module is supplied as a pair. Send us a photograph and we will confirm the match.

Do I need to calibrate after fitting? Run any calibration the app offers with the aircraft empty, then check the reading with a known load.

What load can each sensor carry? Load capacity, accuracy and signal type are not published for this part. We match the module against the one you removed.

Does it come with screws? No. Fixings are not included; keep the originals when you remove the old module.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph your old module and send it to us.

Is it new? Yes. The module is supplied brand new.

Will it fit a T10, T20 or T40? It is identified for the T30 only. Fitment to other models is not claimed.

How do I make it last? Rinse residue from the sensors and connector after work, keep the leads clear of covers and moving parts, and recheck the reported weight with a known load from time to time.
