ASC’s OS series can be used for very low to medium frequency vibration measurements. The OS 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 OS series capacitive accelerometers, OS 115LN and OS 125MF, 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, which results in an improved S/N ratio due to common-mode external noise rejection. ASC Type OS 115LN and OS 125MF operate in a wide temperature range from -40°C to +125°C*. The sensors exhibit exceptional temperature stability, very low non-linearity and can withstand repetitive shocks as high as 6000g’s*. The hermetically sealed OS sensors, ASC OS 115LN and OS 125MF, feature a robust and corrosion proof stainless steel housing with a welded 4-pin connector. The sensors are supplied with 1m detachable cable as a standard. *Applicable to ASC OS 125MF ASC GmbH · Advanced Sensors Calibration · Ledererstraße 10 · 85276 Pf
