High-G piezoresistive shock accelerometer for extreme test and measurement introduced by Endevco

May 16, 2011
SAN JUAN CAPISTRANO, Calif., 16 May 2011. Endevco Corp. in San Juan Capistrano, Calif., is introducing the rugged Endevco model 7270AM6 high-G piezoresistive shock accelerometer for extreme test and measurement applications that must measure long-duration transient events, including near-field shock. The 7270MA6 has frequency-response down to DC or steady state, as well as a built-in mechanical filter housed in aluminum and lined by two layers of elastomeric filter cushion.  

SAN JUAN CAPISTRANO, Calif., 16 May 2011. Endevco Corp. in San Juan Capistrano, Calif., is introducing the rugged model 7270AM6 high-G piezoresistive shock accelerometer for extreme test and measurement applications that must measure long-duration transient events, including near-field shock. Endevco is part of Meggitt Sensing Systems in Fribourg, Switzerland.

The 7270MA6 rugged accelerometer has frequency-response down to DC or steady state, as well as a built-in mechanical filter housed in aluminum and lined by two layers of elastomeric filter cushion. These technologies were first developed by Sandia National Laboratories, Endevco officials say.

Placing elastomeric material on both sides of the accelerometer provides identical sensor response for positive and negative accelerations. The filter also has a damped output with a linear phase shift to mitigate high-frequency shock pulse content to protect the accelerometer from high-G, high-frequency inputs.

The accelerometer has a usable frequency range from DC to 10 kHz, and operates in temperatures from -34 to 66 degrees Celsius. Accessories include the model 126 three-channel DC bridge amplifier; the model 136 three-channel signal conditioner; and the model 436 DC differential voltage amplifier.

Sale of the accelerometer is subject to International Traffic in Arms Regulations (ITAR), which requires a license for shipping it outside the U.S. For more information contact Endevco online at www.endevco.com.
