EGAXT3 Series Accelerometer

Description: The Model EGAXT3 miniature triaxial accelerometers combine a damping ratio of 0.7 (Nominal) with built-in overrange stops that are set to 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. These units feature a Wheatsone Bridge output with compensated temperature range of 20 to 80°C.

Features:
• Miniature Triaxial Design
• DC Response, Low Weight
• 10,000 g Overrange Stops
• Broad Temperature Range
• Static and Dynamic Measurement
• Frequency Response through 3000 Hz
• ±1% Non-Linearity
• -40°C to 120°C Operating Temperature Range
