Remote axle load control and cargo weight calculation are highly demanded features of the GPS tracking systems. We developed Eurosens Difference onboard weighing system which provide features:

■ Individual axle load measurement for truck and trailer.

■ Cargo load calculation.

■ Axle overload alarm.

■ Show axle load and cargo weight at the driver’s display.

■ Transmit axle load and cargo weight values to the GPS tracking system. Eurosens Difference system consist from several parts:

1. Sensors. Can be used as a part of Eurosens Difference onboard weighing and standalone (with GPS tracking system).

Air spring suspension – Eurosens DPS

Leaf spring suspension – Eurosens DDS

2. Electronic unit Eurosens Difference-T (-T2, -T4)

■ Process voltage signal from one load sensor (Difference-T), from 2 sensors (Difference-T2), from 4 sensors (Difference-T4).

■ Stores the parameters (dimensions and weight) of truck or trailer (where its installed).

■ Stores the calibration data.

■ Transmits sensor signal to the digital message in RS485 interface with its address.

3. Eurosens Display RS

■ Receives information about axle loads from the Difference-T controllers.

■ Determines the weight of the cargo based on the mass-dimensions of the tractor or semitrailer truck.

■ Displaying of the axle load and weight of the cargo on the special indicator in the driver’s cab.

■ Warning of exceeding the permissible load on one of the axles.

■ Output to RS485 interface of cargo weight.

Eurosens Difference system supports various configurations of lifting axles, pneumatic suspension schemes and trailers.

Sensor placement and address can be configured with special service software Eurosens Difference configurator.

What you need to know:

■ The protocol of axle load transfer from Difference-T: LLS, each sensor under its own address (0-5).

■ If it is not necessary to measure the weight of the cargo (and warning about exceeding the axle load) – Display is not necessary.

■ The protocol for transferring cargo weight from Display: LLS (addresses 8-9, tractor and trailer)

■ When changing the semitrailer , the system continues to work if the new semitrailer is also equipped with sensors and Difference-T (with calibration). No reconfigurations are required.

Several GPS trackers support remote connection of Eurosens Difference configurator. So, you can calibrate onboard weighinig system remotely. All you need – information about real axle loads from scales. More information – in video.
