Axle load sensors
Simple solution for onboard weighing system
For vehicles with air (GNOM DDE) and leaf spring (GNOM DP) suspensions
Purpose of use
Axle load sensor is designed for axle load and cargo weight monitoring through vehicle tracking systems. Axle load sensor can be connected to analog or CAN input of tracking device or using Bluetooth Low Energy (BLE).
With the help of axle load sensor, vehicle tracking system receive necessary information about location and time of loading and unloading the vehicle.
Users of the system receive information about changes in load on axle in the form of parameters or diagrams.
Features
- mounting on vehicles with leaf springs suspension * and air suspension **;
- compliance with national and European automobile standards for electromagnetic compatibility, resistance to climatic and mechanical stress;
- magnetoresistive operation principle *;
- tensoresistive measurement principle **;
- linear characteristic of the output signal;
- built-in power supply stabilizer — output signal does not depend on supply voltage;
- short-circuit and reverse polarity protection;
- construction with no friction elements for better wear resistance of the sensor.
* GNOME DP
** GNOME DDE
Application

INSTALLATION
GNOM DDE pressure sensor
GNOM DDE is designed for vehicles with leaf spring suspension. Sensor can be installed in the diagnostic hole in the air supply line of vehicle’s air suspension circuit. Sensor measures the pressure of compressed air in pneumatic system of the vehicle and transmits data as an analog signal to telematics terminal. Pressure depends on the weight of the load.
GNOM DP position sensor
GNOM DP is designed for vehicles with leaf spring suspension. To install sensor lever system is used. The devices are fixed to the vehicle frame (chassis) and is connected to the rear axle with the set of leverages. Sensor measures the distance between the frame and the axle which depends on the weight of the load.
