Technoton GNOM S7 Wireless Axle Load Sensor for Air Suspension

Wireless pressure sensor GNOM DDE S7 is used in transport telematics systems (GPS/GLONASS vehicle monitoring systems) to monitor axle loads, determine the axle load in vehicles equipped with air suspension, prevent exceeding axle loads.

Description

Wireless pressure sensor GNOM DDE S7 is used in transport telematics systems (GPS/GLONASS vehicle monitoring systems) to monitor axle loads, determine the axle load in vehicles equipped with air suspension, prevent exceeding axle loads.

GNOM DDE S7 is mounted in the air supply line or in the vehicle air suspension cushion. The sensor measures pressure of compressed air in the air suspension circuit which is changing depending on loading of vehicle. The more cargo is in the vehicle body, the more axle load is and the higher is the pressure in the vehicle pneumatic system.

GNOM DDE S7 may be employed for monitoring the vehicle axle load within the transport Telematics system (GPS/GLONASS vehicle monitoring systems) or for independent operation. Axle load sensor operates in BLE-radio mode, that means, data is sent to several devices at the same time: Bluetooth-display, smartphone, tablet. This enables the driver to monitor axle load and prevent overweight during loading and unloading works.

Technoton

Technoton was established in April 2000, at the early stage of emerging market of automotive telematics and GPS tracking systems. We started with development and manufacture of GPS tracking devices, fuel level sensors and fuel flow meters. Soon we focused on solving tasks of fuel consumption measurement and fuel usage monitoring, safe CANbus data reading and analysis.

Technoton’s technical team includes highly-qualified engineers and developers, who have wide expertise in micro controller units, mechanical engineering, computer science, programming and diagnosis.
