Shock accelerometers

Tuesday, 10 November, 2009 | Supplied by: Thermo Fisher Scientific


PCB Piezotronics has introduced the PCB series 3991/3501 of MEMS shock accelerometers.

The miniature, high-amplitude, DC response sensors can measure long-duration transient motion and respond to and survive fast rise times typical of high-g shock events.

The air-damped sensing element is micro-machined from silicon and incorporates a seismic mass, protective over range stops and a full-active, piezoresistive Wheatstone bridge and is said to be the industry’s smallest, most accurate and durable accelerometer.

Slight air-damping reduces the resonant amplification which increases measurement accuracy and over-range stops give the sensor good survivability.
