For vehicles with a leaf spring suspension!
High-accuracy axle load sensor. It is installed on the axle and measures its strain deformations.
Eurosens DSS contains strain transducer, amplifier and microcontroller. Sensor has to be screwed tightly to the steel plates, mounted on the axle with a welding. After sensor installation and calibration built-in microcontroller provides axle load data to the CAN J1939 standard interface or RS485 interface (LLS protocol). Protocol messages contain axle load in kg or tons.
EUROSENS DSS CAN AXLE LOAD SENSOR
DIGITAL STRAIN SENSOR
High accuracy axle load sensor eurosens® DSS is mounted on the vehicle axle and measures its microstrains using a strain gauge. The built-in microcontroller determines the axle load in kilograms and transmits the data via interface CAN J1939.

- Suitable for leaf springs of any state and properties.
AXLE LOAD SENSOR APPLICATION
Digital load сontroller eurosens DSS 485 is designed to convert the amount of deformation of a vehicle’s part (e.g., a car bridge) under load and transfer information via RS 485 bus.
Digital load cell eurosens DSS 485 is used in eurosens Difference axle load systems.
AXLE LOAD SENSOR GUIDANCE FOR USE
During the installation of eurosens DSS 485 follow the Safety rules and standards of your company. The сontroller is mounted with two plates from the delivery package. Plates are attached by welding using a slipway. The deviation of the plates from the surface after welding should not exceed 0.05 mm. Tightening of sensor attachment screws is performed with tightening force not less than 25 Nm, but not more than 35 Nm.
Calibration and configuration of eurosens DSS 485 is carried out with eurosens Destination CAN service kit. Additional operational settings are performed with our service software.
Operation recommendations are provided in the User manual. During the welding process it is highly recommended that the load сontroller be disconnected from the power supply and unplugged.
