Advanced Sensors & Calibration (ASC) GmbH, the leading manufacturer of acceleration and angular rate sensors as well as IMUs (Inertial Measurement Units), has further developed its uniaxial capacitive MEMS acceleration sensor ASC OS115. The improved sensors are available in two versions: the ASC OS115LN (low noise) and the ASC OS125MF (medium frequency). These feature a welded and thus hermetically sealed construction with a side-mounted, four-pin plug and removable cable. The ASC OS accelerometers are suitable for applications in space, underwater, or during very long exposure to extreme humidity typically found in test and measurement applications in automotive, rail, wind energy, monitoring, building surveillance, marine, and space, among others.
