Rosemont, IL — Endevco Corp . introduces the lowest-noise compact seismic accelerometer and provides two hands-on demonstrations showing critical measurement applications related to automotive safety and drop testing, in booth 98 at Sensors Expo 2007 at the Donald E. Stephens Convention Center in Rosemont, IL, June 11-13. Also at that location, the Robot & Vision Show will be held June 12-14. Endevco is celebrating its 60th anniversary in 2007.
Model 87, said to be the world’s lowest-noise compact seismic accelerometer, is among Endevco booth highlights. Company says the new sensor is 70% lighter than traditional integral-electronics piezoelectric (IEPE) seismic accelerometers and designed for measuring ultra-low-level seismic events and low-frequency vibration on structures and objects. The model 87 is hermetically sealed against environmental contamination, is available in 1 V/G or 10 V/G sensitivity, delivers the best signal to noise through state-of-the-art integrated electronics, and provides near-dc frequency response, Endevco explains. It incorporates an advanced ultra-low-noise hybrid circuit operating in a constant current mode. A simple two-wire system transmits low-impedance voltage output and required power. Signal ground is isolated from the outer case and mounting surface to prevent ground loops. A specially designed cable assembly is available as an optional accessory.

Hands-on demonstrations at the booth show high g levels that Endevco sensors can measure in an interactive, competitive, and memorable way.

“Endevco Bob” is an anthropomorphic test dummy (ATD) with implanted Endevco sensors (models 7264D and 7269), ready to take hits and register force, along with sensor-equipped boxing gloves. Meggitt group company , says it is “the leader in sensing solutions for demanding vibration, shock and pressure applications.” Endevco was founded in 1947 and has headquarters in San Juan Capistrano, CA.
