Capacitive MEMS Technology
The accelerometers are based on a capacitive MEMS technology and can be used in a low
frequency response up from 0Hz. 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.

The models ASC 4321 and ASC 4325 have been developed for the demanding requirements of
different applications. The highly robust housing and the connecting cables are suitable for
the rough application areas in automotive, train, military and so on. These ASC accelerometers
benefit from the high stability of the chip technology with a low bias and an excellent scale
factor temperature coefficient.
The ASC 4321 and ASC 4325 are fully compensated over a wide temperature range and are
factory calibrated. Both models are shock resistant up to at least 7000g. As 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. A very high flexible
and rugged cable provides a simple mounting.
The stainless steel package of the ASC 4325 provides a high resistance to strong environmental
influences. The ASC 4321 and ASC 4325 are equipped with 6 meter cable as standard.
