The Model 4020 & 4030 are low noise,
signal conditioned DC accelerometers
packaged in a durable molded housing.
The accelerometers are offered in ±2g &
±6g ranges with a nominal 0-200Hz
bandwidth. The model 4020 is a dual axis
configuration (X&Y axes) while model 4030
is a triaxial configuration.
The capacitive silicon MEMS sensing
element offers high resolution and long
term stability for critical measurement
applications.
APPLICATIONS
Low Frequency Vibration Monitoring
Tilt & Inclination Measurement
Motion Measurements
