TZH6a is a six-channel fully isolated and independently powered hall speed sensor designed and produced by Shanghai renhao electronic technology co., LTD. The sensor is installed on the cover of the axle head of the locomotive and can be used to detect the rotation speed, linear speed, acceleration of the axle and the running direction of the vehicle.There is no contact between the sensor and the tested gear, no wear, easy installation, it has the characteristics of wide speed measurement range, wide temperature adaptation range, strong seismic resistance, etc..
