Detection of lateral or vertical variations during passage of wheels at railway points or crossings to give wear indication uses sensor connected to T-shaped actuator detector

摘要

The detector has a sensor connected to an actuator, and sends signals to a processing circuit. T-shaped actuator (4) moves vertically and is able to tilt. The head (11) of the 'T' cooperates with switches, sensors or strain gauges inside the detector housing (6). The shank of the 'T' is supported on a pivot or by an elastic collar to allow it to tilt.
