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.

Description
The models ASC 4511LN and ASC 4515LN 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 noise level
and a low bias and an excellent scale factor temperature coefficient.
The ASC 4511LN and ASC 4515LN are fully compensated over a wide temperature range and
are factory calibrated. 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. ASC 4511LN and ASC 4515LN are equipped with 2 meter
cable as standard.
