About the KSI84Ax Acceleration Sensor

The Capteurs de vibrations of the KSI84xx family are used to measure vibration acceleration, velocity or displacement on machines and objects. The sensors measure the vibration amplitude within a specified frequency range in axial sensor direction and outputs the measuring result as a 4-20 mA current loop signal. The sensor is supplied with power via the same signal line. The sensor parameters are adjustable. There are different types for different applications in several measuring ranges. The sensors comply with the specifications for vibration measuring devices according to ISO 2954.
