Eurosens Difference onboard weighing system

Remote axle load control and cargo weight calculation are highly demanded features of the GPS tracking systems.

Mechatronics developed Eurosens Difference onboard weighing system which provides the following features:

• Individual axle load measurement for truck and trailer.
• Cargo load calculation.
• Axle overload alarm.
• Shows axle load and cargo weight at the driver’s display.
• Transmits axle load and cargo weight values to the GPS tracking system.

Eurosens Difference system consists of several main parts:

1. Axle load sensors. Can be used as a part of Eurosens Difference onboard weighing system or as standalone units (with GPS tracking system).

Air spring suspension – Eurosens DPS	Leaf spring suspension – Eurosens DDS	Universal axle load sensor Eurosens DSS

Each sensor has built-in electronic module performing functions:

• Processes sensor signal, makes some noise filtering and data averaging;
• Stores the geometric parameters of the truck / trailer ;
• Stores calibration data;
• Calculates axle load in kg/tons and sends to external interface (analog, RS485 or CAN bus)

2. Eurosens Display RS

• 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:

Eurosens DPS / DDS / DSS sensors can be connected directly to the GPS tracker and send axle loads (in tons/kg) into GPS tracking system. On the server side you can calculate the total weight of the truck/trailer, the weight of the cargo and other parameters using formulas (if your software supports that). So what is the difference between the Eurosens Difference OnBoard Weighing System and standalone sensors?

From a hardware point of view, onboard weighihg system has an on-board driver display. Because to display the cargo weight we have to do all the calculations onboard. Therefore, the onboard weighing system differs from standalone sensors in the following functions:
• The sensors additionally contain information about the vehicle and the trailer (dimensions, number of axles, distance between axles) and an installation map of axle load sensors.
• When connecting another trailer, also equipped with weighing system sensors, the parameters of the tractor-trailer system (dimensions, distances, sensor calibration) are automatically updated in all sensors. Thus, changing the trailer does not lead to incorrect calculations of the total weight of the truck-trailer combination and cargo weight.
• All information is displayed to the driver.

Thus, a set of separate Eurosens DDS / DPS / DSS 485 axle load sensors turns into an on-board weighing system only by adding Eurosens Display RS and this is necessary in the following cases:
• It is necessary to display axle loads / vehicle and cargo weight to the driver
• It is necessary to automatically support “on the fly” trailer change without any additional steps to change the system settings / calibrations.
