Inside the sensor element, the seismic mass is connected with two conductive capacitor plates. If the seismic mass oscillates between the two capacitor plates the capacitance will change. This capacitance change is converted via an ASIC (Application Specific Integrated Circuit) into an analog signal. Description The model ASC 4311LN is an uniaxial accelerometer based on capacitive technology. It is over a wide temperature range fully compensated and factory calibrated. The sensor has been developed specifically for measuring relatively small accelerations, as required in the aerospace or automotive sector, for example. Because capacitive technology is used, extremely small measuring ranges are possible. The amplified output is easy to use with a data acquisition unit. The signal is independent from the power between +8VDC to +30VDC. The package is hard anodized aluminium that is rugged for automotive, industrial and military applications. A very high flexible rugged cable provides a simple mounting. The ASC 4311LN is equipped as standard with 6m cable. It is a Low Noise version and has a better frequency response. Owing the lower noise the ASC 4311LN provides a higher resolution. The stainless steel package of the ASC 4315LN provides a high resistance to strong environmental influences.
