Product Description

The key components in capacitive accelerometers are high-quality micro-electro-mechanical systems (MEMS). This technology enables the measurement of static (DC) and constant accelerations, which can be used to calculate the velocity and displacement of moving objects. Depending on the design of the spring-mass-damping system, however, it is also possible to detect dynamic (AC) accelerations with amplitudes up to ±40 g and within a frequency response range of up to 630 Hz (±5 %) or 2.4 kHz (±3 dB).

The digital accelerometers of type ASC DiSens® ECO-Rail comply with the standard EN 50155, Railway applications - Rolling stock - Electronic equipment. The sensors have successfully passed all necessary tests regarding environmental and mechanical-dynamic as well as electromagnetic compatibility requirements. The integrated electronic circuitry enables the digital interfaces CAN and meets galvanic isolation. The sensors provide already implemented filter settings enabling a sampling rate of up to 4 kHz at a 3dB-corner frequency of 1 kHz as well as configurable measurement range settings. 

The sensors feature a robust and reliable stainless-steel housing leading to hermetic sealing and protection class IP68. The cable gland VariaPro Rail was tested according fire protection standards DIN EN 45545-2 and DIN EN 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:
