The accelerometers are based on a capacitive MEMS technology and can be used in a low frequency response up from 0 Hz. 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. These ASC accelerometers benefit from the high stability of the chip technology with a low noise level and a low bias and an excellent scale factor temperature coefficient. In addition, A very high flexible and rugged cable provides a simple mounting. ASC 5411LN and ASC 5415LN are equipped with 6 meter cable as standard.
