Meggitt's Endevco model 72 series high-g piezoresistive shock accelerometers support a variety of acceleration, vibration and shock measurements

Meggitt Sensing Systems has announced the launch of the Endevco model 72 series, a family of high-g SMT-mountable piezoresistive accelerometers designed to support a variety of high-reliability acceleration, vibration and shock measurements.

Available with a 20,000 g measurement range and a soon-to-be-released 60,000 g version, the Endevco model 72 series offers broad frequency response, minimum zero shift post-shock event and a Class 3 rating for electrostatic discharge protection. Its low-profile, miniature, hermetically sealed LCC package weighs 0.16 grams for minimized mass loading effects. The LCC package can be SMT mounted using production pick-and-place machines and reflow solder for easy installation.

The monolithic, four-active arm bridge circuit design of the Endevco model 72 series incorporates a highly sensitive MEMS sensing element with light gas damping to attenuate resonance. Mechanical stops are included to increase ruggedness and reduce the likelihood of breakage under overload conditions, with stability and reliability to four times over-range. With a frequency response extending down to dc (steady state acceleration) and a minimum post shock zero shift, this accelerometer is well suited for measuring long duration shocks associated with a variety of automotive, aerospace, and general test and measurement applications.
