Axle counting sensor

Datchic_ZRAxle counting sensor ZR with multipurpose sensor fixing to rail set CL is mounted to the rail on the inside of the gauge track at the boundary of controlled track section with observance of obstruction and rolling stock clearance. It consists of a sealed dielectric casing inside which a printed-circuit board with electronic components is installed.

When a train vehicle unit passes through the sensor sensitivity zones, the signals required for detecting the axle movement are generated successively. Axle direction and travel speed are sensed too. The information on axle counting sensor condition or fault is transmitted via RS-485 interface to signal receive/process module NP.
