The rotation control sensors


Based on the data obtained, the sensor determines the modes of operation of the concrete mixer truck: mixing of the solution and unloading of the solution.


The sensor is designed to measure the speed and determine the direction of rotation of the container of the concrete mixer truck.

The sensor detects rotation in the plane perpendicular to the ground, as well as at an angle of up to 45 degrees from the plane perpendicular to the ground.
