Sensor is the heart of a measurement system. A sensors coverts physical parameters like temperature, humidity, speed, etc. into a signal which is measured electrically. Sensors can be used in various devices it can also use for monitoring the railway infrastructure such as bridge, rail tracks along with the vehicle health monitoring such as bogies, wheels, and wagons.
Wheel sensors are used in railway, metro and tram applications to measure speed in the motive power system and to control the brakes to prevent brake locking and wheel slippage. Wheel sensor was developed to provide a presence detection system that is simple to install highly reliable and easy to maintain.

Railway bridge damage status is monitored by the sensor and transfer through wireless modules. Railway bridge damage status is monitored by the sensor and transfer through wireless modules. It is more cost effective. Transmitting signals are immediately transfer. It can be applied in railway track damage detection, industrial and access control and in other remote control system.

The sensor is ideal for use in environment containing iron because sensors does not attract any magnetic particles such as iron chips and dust. Wheel sensor for railway withstand high shock and vibration loads due to encapsulated electronics, they are extremely thin and easy to mount using standard flanges. The wheel sensor is easily integrated into the operation of typical DC electric switch machines, these factors are expected to drive the demand for rail wheel sensor during the forecast period.
