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

Options
 Customised Cable Length
 Customised Connector
 TEDS Module

The model ASC 4311LN is an uniaxial accelerometer based on capacitive technology. It is over
a wide temperature range fully compensated and factory calibrated. The sensor has been developed specifically for measuring relatively small accelerations, as required in the aerospace
or automotive sector, for example.

Applications
 Structural Monitoring and
Testing
 Endurance Testing
 Brake Test
 Vibration Monitoring
 Civil Engineering
 Modal Analysis
 Vehicle Testing
 Automotive Ride Quality
& Comfort
 Railway Engineering
 Flutter Test

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. The package is hard anodized aluminium that is rugged for
automotive, industrial and military applications.
A very high flexible rugged cable provides a simple mounting. The ASC 4311LN is equipped as
standard with 6m cable. It is a Low Noise version and has a better frequency response.
Owing the lower noise the ASC 4311LN provides a higher resolution.
The stainless steel package of the ASC 4315LN provides a high resistance to strong environmental
influences.
