May 15, 2011, San Juan Capistrano, California, USA– Meggitt Sensing Systems, a Meggitt group division, has introduced the Endevco® model 7270AM6, a highly rugged high-g piezoresistive shock accelerometer with frequency response capabilities down to DC or steady state, designed to support a variety of extreme testing requirements.
Incorporating the use of high-performance technologies first developed by Sandia National Laboratories, the built-in mechanical filter of the Endevco® model 7270AM6 consists of an aluminum housing lined by two layers of elastomeric filter cushion. With the presence of the elastomeric material on both sides of the accelerometer, sensor response is thus identical for both positive and negative accelerations. The mechanical filter assembly, featuring a damped output with a linear phase shift, has also been designed to mitigate high-frequency shock pulse content in order to protect the accelerometer from high-g, high-frequency inputs that would otherwise exceed typical sensor over-range limits. The extended frequency range of this DC response accelerometer allows the model 7270MA6 to measure long duration transient events, including near-field shock. The accelerometer offers a usable frequency range from DC to 10 kHz, exhibiting excellent performance stability over a temperature range of -34 to +66°C (-30 to +150°F).
Recommended accessories for the Endevco® model 7270AM6 include the new model 126 three-channel DC bridge amplifier; the model 136 three-channel signal conditioner; and the model 436 DC differential voltage amplifier.
