MEMS Capacitive Accelerometer for Railway Applications
The accelerometers of type ASC RAIL-x15LN are based on proven MEMS technology and capacitive operating principle. The integrated electronic circuitry enables a differential analog voltage output (±4 V FSO) and flexible power supply voltage from 6 to 40 VDC. The LN (Low Noise) accelerometers from ASC provide an outstanding noise performance from 7 to 400 µg/√Hz which is essential for demanding measurements of smallest frequencies and amplitudes.
The sensors feature a robust and reliable stainless-steel housing (V2A material number 1.4301) leading to hermetic sealing and protection class IP68. The cable gland VariaPro Rail was tested according fire protection standards DIN EN 45545-2 and 45545-3. Furthermore, rail certified and integrated cable RADOX TENUIS-TW 600V MM S complies with the technical requirements of EN 50306 (particularly low temperature and high level of oil and fuel resistance). It provides a high level of thermal resistance due to standard fire protection on railway vehicles according to:
The application-specific housing enables reliable operation even in harshest environmental conditions. They are ideally suited for bogie stability tests and monitoring applications of vehicles and their components in the rail transport sector.
