Meggitt Sensing Systems, a Meggitt group division, has announced the launch of its Endevco model 72-60K piezoresistive shock accelerometer. As the newest member of its model 72 series, the sensor offers a 60,000 g measurement range, light gas damping and four times over-range shock survivability. The series is designed to support a variety of acceleration, vibration and shock measurements, and especially, the long duration shocks found in weapons testing, missiles and munitions, fuze/safe and arm and high-shock data recorder applications.
Design of the Endevco model 72-60K features a patented, monolithic, four-active arm bridge circuit design incorporating the use of Meggitt’s own proprietary sensing element. The element is housed within a low-profile, miniature, seam sealed leadless chip carrier (LCC) package, weighing 0.16 gram. Included integral mechanical stops at a minimum of 2X allow for 1.5X linear over-range.
The Endevco model 72 series also offers a Class 3 rating (>4000 V " Human Body Model) and integral electrostatic discharge (ESD) protection against potential process damage. A combination of light gas damping and mechanical over-travel stops serves to attenuate resonance. According to the company, the model 72-60K also exhibits excellent performance stability and frequency response extending down to DC (steady state), with low power consumption and optional input voltage.
