MODEL EGAXT3TRIAXIAL ACCELEROMETERSPECIFICATIONSMiniature Triaxial Design
mV Output DC Response
Critically Fluid Damped
10,000 g Over-range Stops
Broad Temperature Range

The Model EGAXT3 miniature accelerometer combine
a damping ratio of 0.7 (nominal) with built-in over-range
stops that protect the unit against 10,000g shocks. Thisis ideal for applications which may experience roughhandling or in situations where the accelerometer must
survive a high initial overload in order to make a low gmeasurement.
The model EGAXT3 features a common piezo-resistive
Wheatstone Bridge design with a mV output. Theaccelerometer incorporates an inline temperaturecompensation module which ensures accurate output
over full operating temperature range.
