Meggitt Sensing Systems Launches New Endevco® Model 72 Series High G Piezoresistive Shock Accelerometers
San Juan Capistrano, California, USA - Meggitt Sensing Systems, a Meggitt group division, has announced the global market launch of the Endevco® model 72 series, a new 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 just 0.16 grams for significantly minimized mass loading effects. The LCC package can be SMT mounted using production pick-and-place machines and reflow solder for easy installation.
The patented, monolithic, four-active arm bridge circuit design of the Endevco® model 72 series (US patent 6,988,412) 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 ideal for measuring long duration shocks associated with a variety of automotive, aerospace and general test & measurement applications.
Recommended accessories for use with the Endevco® model 72 series include the model 136 three-channel bench top DC amplifier or model 436 three-channel rack mounted DC amplifier, both available from Meggitt Sensing Systems.
