Meggitt’s Weight-Less, Economical Endevco Model 7287 Measures Shock in Testing Applications

Meggitt Sensing Systems declared the launch of a novel, miniature, weight-less piezoresistive accelerometer called the Endevco model 7287.

The mass of the system is lower than one gram and provides low-cost calibrations of prolonged shocks which develop during shipping container shock testing, product and packaging drop testing, high-g destructive testing, and jack hammer testing operations.

Endevco Model 7287

The Endevco model 7287 supplies a calibration range of 2,000g with 200mV measurement output and 20,000Hz resonance frequency. This particular version employs a MEMS sensor with in-built mechanical stops and encompasses a tiny, low-weight, easily installable package for minimum weight loading of the experimental structure. This rigid sensor configuration furnishes robustness, constancy and security with a 4,000Hz frequency responsiveness from DC at ±5%, with<1% non-linearity and 10,000 g ruggedness to the shock. The Endevco model 7287 exhibits reduced damping, thus eliminating the phase shift through out the needed frequency range.

The configuration of this unique model has drawn upon decades of proven experience in manufacturing these types of sensors for the automotive crash test market, proved successful with the advent of advanced sensing technologies used in the production process of automotive sectors and is recently being taken up for the common tests and calibration applications. The durability and safety of this model highlights that the information is logged based on the necessity, cost-effectively. These units are accessible with firm mounting or with in-built brackets to facilitate the screw mounting and are provided with a robust PVC cable of the desired length.    The standard supplements to be used with the Endevco model 7287 covers the model 4430A bridge transducer signal conditioner, Oasis- model 4990A with multiple channel signal conditioner or 136 triple-channel DC signal conditioner, according to the company.
