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 model ASC 3521 is an uniaxial accelerometer based on capacitive technology. It is over a
wide temperature range fully compensated and factory calibrated. The ASC 3521 has been
developed specifically for measuring relatively low level accelerations, as required in the
aerospace or automotive sector, for example.
The amplified output is useable easy on 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.
With the cube form there are more possibilities for mounting. A very high flexible and rugged
cable provides a simple mounting. The four wire output can be connected to all data
management systems.
