For safe and efficient railway operations, critical components must work correctly. Continuous maintenance and monitoring of rail car wheels and essential moving elements is vital. SkyMEMS Accelerometers are used to monitor several types of mechanical motions such as inertial force (acceleration), tilt (inclination), vibration and shock.
SkyMEMS produces accelerometers based on silicon MEMS capacitive sensors, which enjoy higher performances in terms of size, power, reliability, long-term stability, signal to noise and robustness, which is suitable for today’s ever-evolving field of railway transportation

CRH High Speed Train
SkyMEMS MEMS accelerometers have widely applied in the CRH high speed train systems, it is used in tilt control systems for high-speed trains, which is designed to improve passenger comfort. And it is also used in train shock and vibration monitoring.
MA1000 MEMS capacitive accelerometers are famous for their high reliability under harsh conditions and have been successfully qualified for safety critical railway applications.

Metro Train
MA1000 MEMS capacitive accelerometers are also widely used in metro train, they offer the best performance stability with shock resistance, as well as the lowest non-linearity and noise in the marketplace. Each product is fully tested and qualified to the highest SkyMEMS standards. It embeds a self-test function for your confidence at all time.
SkyMEMS accelerometers are successfully operating in metro trains in more than 15 cities in china.
