Series 3991/3501 MEMS shock accelerometers from PCB Piezotronics are capable of measuring long-duration transient motion as well as responding to and surviving extremely fast rise times typical of high-g shock events. Offered in packaged and OEM configurations, the high-amplitude, dc-response acceleration sensors are able to fulfill a variety of installation requirements. Measuring 2.5 x 1.7 x 0.9 mm (0.1 x 0.07 x 0.04 in), the sensor incorporates a seismic mass, protective over-range stops, and a full-active, piezoresistive Wheatstone bridge, making it the industry’s smallest shock accelerometer. The slight air damping reduces the resonant amplification, increasing measurement accuracy.
