EGAXT3 Mini Critically Damped Triaxial Accelerometer
3-axial acceleration sensor in miniature design with an overload limit of 10,000g for all 3 axes
About the EGAXT3 Mini Critically Damped Triaxial Accelerometer
The Model EGAXT3 miniature accelerometer combines a damping ratio of 0.7 (nominal) with built-in over-range stops that protect the unit against 10,000g shocks. This is ideal for applications which may experience rough handling or in situations where the accelerometer must survive a high initial overload in order to make a low g measurement.
The model EGAXT3 features a common piezo-resistive Wheatstone Bridge design with a mV output. The accelerometer incorporates an inline temperature compensation module which ensures accurate output over full operating temperature range
