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 onboard weighing system

Eurosens Difference system consist from several parts:

1. Sensors

Air spring suspension – Eurosens Difference 01
Leaf spring suspension – Eurosens Difference 02

Eurosens Difference axle load sensors

Also you can use any sensors with analog (voltage) output : vehicle sensors, strain gauges, load cells, pressure sensors, etc.

2. Electronic unit Eurosens Difference-T

■ Process voltage signal from one load sensor.
■ 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:

■ Each analog sensor is connected via a Difference-T controller
■ 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.
