Application of displacement sensing in railway market

Track status monitoring

To improve the safety of railway transportation and avoid train derailment, eddy current sensors can be used to measure track displacement at critical locations such as bends. Detect the lateral and longitudinal displacement of the tracks on both sides when the train passes through, calculate the stress situation of the tracks on both sides based on the track stiffness, determine the risk of train derailment, and promptly detect problems and issue alarms. Due to the fact that most tracks are located in outdoor environments, sensors need to have good temperature stability and maintain measurement accuracy in various weather conditions. Eddy current sensors have good environmental adaptability and are particularly suitable for such applications.
