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. Description ASC's MF series capacitive accelerometers, 5521-MF and 5525-MF, are analog voltage output sensors. The sensors can be powered by a DC power supply (+5V to +40V) where the output voltage is independent of the supply. The sensors operate 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 5521-MF and 5525-MF operate in a wide temperature range from -40°C to +125°C. The sensors exhibit exceptional temperature stability, very low non-linearity (<0.5%) and can withstand repetitive shocks as high as 6000g's. ASC Type 5521-MF features a lightweight Aluminium housing and Type 5525-MF features a rugged, corrosion proof stainless steel housing. The sensors are supplied with 6m integral cable as a standard.
