Load sensor Mechatronics Eurosens Difference onboard weighing system

Mechatronics Eurosens Difference onboard weighing system

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 Air spring suspension – Eurosens DPS ,  Leaf spring suspension – Eurosens DDS 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 (-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

Configuration №1. All air springs are connected parallely – here is enough 2 pressure sensors .The first one is installed on the tractor (truck itself), the other one – on the semitrailer

Configuration №2. 2 sensors on the tractor (truck) and 2 sensors on semitrailer

Configuration №3. 2 sensors on the truck and 4 sensors on semitrailer (in this configuration, as a rule, one axle is lifting)

2 sensors on the tractor (truck) and 6 sensors on semitrailer (as a rule, there are 2 lifting axles here)

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