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 3421 is an uniaxial accelerometer based on capacitive MEMS technology. It is
fully temperature compensated and factory calibrated. The sensor has specifically been developed for monitoring, tilt and comfort vibration measurings. The four wire output can be
connected to all data management systems. The hard anodized aluminium housing is epoxy
sealed and ground isolated. A 4-pin Comtronic connector is used as a standard and therefore
the mounting can easily be handled.
The model ASC 3421 is based on Low Noise technology which provides an excellent
resolution.
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.
A very high flexible and rugged cable provides a simple mounting. The ASC 3421 is equipped
as standard with 6m cable.
