Omschrijving Capacitieve Accelerometer ASC 4421MF

The Medium Frequency Capacitive Accelerometers of Althen Sensors & Controls (MF series ASC 4421MF) are based on capacitive sensing technology and produce an analog voltage proportional to the input acceleration. The accelerometers can measure both static (gravity) and dynamic accelerations. The MF series can be used for very low to medium frequency vibration measurements from 0Hz to 2.5kHz.

The MF series features a MEMS sensor element where the seismic mass is connected between two conductive capacitor plates. When subjected to an input acceleration, the seismic mass oscillates between the two capacitor plates and there is a change in the capacitance. This change in capacitance is converted via an ASIC (Application Specific Integrated Circuit) into a low impedance analog voltage output signal.
