58 Auto Safety Testing Accelerometer

Piezoresistive MEMS accelerometer designed for crashtest, offroad, impact, transport

About the 58 Auto Safety Testing Accelerometer

The Model 58 Accelerometer is a MEMS DC response accelerometer designed for auto safety crash testing.  The accelerometer is packaged in a rugged housing with a shielded low-noise cable specifically designed for crush zone testing. The model 58 accelerometer features a full bridge output configuration with a temperature range from -20 to +85ºC. A slight amount of internal gas damping provides outstanding shock survivability and a flat amplitude and phase response up to 4000Hz.
