Requirement
SAM Machinety requires real-time weighing and dosing of the load on a moving fertilizer spreader during field operations.
The weighing system must operate in challenging agricultural environments, subject to dust, vibration, and moisture. It must also be compact to adapt to the moving machine and integrate flawlessly with the control system.
Our solution
For the weighing system on the spreader, we used:
How does it work?
Each fertilizer spreader features a custom frame with 8 FTP IP68-rated 5,000 kg load cells.
Each load cell is installed at key weighing points under the hopper and connected directly to the TLM8 weight transmitter.


The weight transmitter is mounted in a box on a custom Omega/DIN plate, which is mounted on a rubber support next to the hydraulic and electrical system.
The load cells detect the weight of the product inside the spreader in real-time, and the weight transmitter communicates the data via CANopen protocol to the control unit.
The operator sets the desired product flow rate through the control unit, which then adjusts the product release in the field based on the machine's ground speed.
The weighing data is also used to alert the operator about the reaminig product quantity and the total product distributed.
