About the ASC 4325MF Capacitive Accelerometer

ASC’s Medium Frequency (MF series) capacitive accelerometers are based on the capacitive sensing technology and produce an analog voltage proportional to the input acceleration. The accelerometers can measure both static (gravity) and dynamic accelerations. ASC’s 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.

ASC’s capacitive accelerometer 4325MF is an analog voltage output sensor. The sensor can be powered by a DC power supply (+5V to +40V) where the output voltage is independent of the supply. The sensor operates in a differential configuration with ±2.7V full-scale output. For the full-scale acceleration range, the output swings between 0.3V and 3V. The differential configuration results in an improved S/N ratio and a better performance.
ASC Type 4325MF operates in a wide temperature range from -40°C to +125°C. The sensor exhibits exceptional temperature stability, very low non-linearity (<0.5%) and can withstand repetitive shocks as high as 6000g’s.
ASC Type 4325MF features a rugged, corrosion proof stainless steel housing. Also available is Type4321MFwhich features a lightweight aluminium housing. The sensors are supplied with 6m integral cable as a standard.
