Axle load sensor monitors vehicle weight, ensuring accurate cargo control.
Axle load sensor is designed for cargoweight control on each of the axles of a vehicle using a tracking systems. Axle load sensor can be connected to the analog input of tracking device for example, vehicle sensors, displacement sensors, strain gauges, load cells, pressure sensors, etc.
Withaxle load sensor, a vehicle tracking system gets valuable information about the location & time of loading, unloading, notifies drivers about exceeding the axle load, shows the determined parameters on the display in the driver’s cab and to transfers the values of the loads along the axes and the weight of the cargo to the monitoring system.
The number of sensors installed on a truck can vary from 2 to 12 pcs, depending on the configuration of vehicles. The weight parameters and axial loads are read by the tracker via the RS-485 interface using the data protocol.
The weighing system includes: a Eurosens Difference-T controller, a pressure sensor (a displacement sensor) or other, Display RS and a set of cables.
Features of Eurosens Difference T controller
The number of sensors to be installed and its location primarily depends on the number of axles on vehicles, the number of lifting axles and the type of suspension used. For air suspension – Difference 01 pressure sensors must be used and for leaf spring suspension – Difference 02 displacement sensors (or other analogue sensors).
The method of determining the location and number of sensors consists of the following:
a.) It is necessary to determine the number of axles of vehicles. The nearby axes (trolley) are considered as one conditional axis.
b.) After it is needed to determine the minimum number of sensors to be installed, taking in account that on each conditional axis there must be installed at least one sensor. The exception is the “tractor + semitrailer” configuration, where no sensor is placed on the front axle.
In this case, the load on the front axle is determined based on the load on the tractor’s rear axle, on the position of the fifth wheel coupling and the distance between the front and rear axles of the tractor.
