EGCS-D1S Series Accelerometer

The Model EGCS accelerometers combine a damping ratio of 0.7 (Nominal) with built-in overange stops that are set to protect the unit against 10,000 g shocks.

EGCS-D1S Series Accelerometer

Description: The Model EGCS accelerometers combine a damping ratio of 0.7 (Nominal) with built-in overange stops that are set to protect the unit against 10,000 g 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:
• Rugged Design
• DC Response
• 10,000 g Overange Stops
