Device Measures Rotational, Torsional Accelerations

A new angular accelerometer has been designed to achieve accurate measurements of rotational or torsional accelerations. The Model 7302BM4 accelerometer is suited to measure irregularities in shaft and drive train rotation for machine and turbine monitoring. Other applications include crash testing and suspension/chassis vibration monitoring—the accelerometer is often employed in anthropomorphic crash test dummies to measure rotational body accelerations experienced under impact. The sensing system consists of a temperature compensated piezo-resistive accelerometer, designed with a Wheatstone bridge element providing high rejection of cross-axis angular and linear accelerations. The device is fluid-damped to optimize frequency and phase response within a 0°F to 250°F temperature range. It has a frequency response from 0 to 1,600 Hz and provides a linear output to 50,000 rad/sec². Nominal sensitivity is 5.0 mV per krad/sec² with 10 Vdc excitation voltage, and high angular and linear shock resistance. ENDEVCO, San Juan Capistrano, CA. (949) 493-8181.
