Accelerometer Accurately Measures Rotational

or Torsional Accelerations

 

SAN JUAN CAPISTRANO, Calif. - May 12, 2004 - Endevco’s Model 7302BM4 angular accelerometer is designed to provide accurate measurements of rotational or torsional accelerations. The sensing system consists of a temperature compensated piezoresistive accelerometer, uniquely designed with a Wheatstone bridge element that provides high rejection of cross-axis angular and linear accelerations. Typical applications for the Model 7302BM4 accelerometer include the measurement of irregularities in shaft and drive train rotation for machine and turbine monitoring. The accelerometer is ideal for dynamic automotive applications including crash testing and suspension/chassis vibration monitoring. The accelerometer is also often employed in anthropomorphic crash test dummies to measure rotational body accelerations experienced under impact.

 

The Model 7302BM4 is fluid-damped to optimize frequency and phase response within a 0° to 250°F (-17°C to 120°C) temperature range. The accelerometer offers a stable frequency response from 0 to 1600 Hz and provides a linear output up to 50,000 rad/sec2. The 7302BM4 accelerometer provides a nominal sensitivity of 5.0 mV per krad/sec2 with 10 Vdc excitation voltage and offers high angular and linear shock resistance.

 

Endevco’s Model 136 Three-Channel System, Model 4430A or OASIS 2000 Computer Controlled System are recommended as signal conditioner and power supply.
