ENDEVCO Debuts High Resonance Crash Sensor Provides Unparalleled Measurement Accuracy

 

 

SAN JUAN CAPISTRANO, Calif. – June 8, 2005 – Endevco Corporation announced the development of the High Resonance Crash Sensor. For 30 years ENDEVCO’s piezoresistive accelerometers have been the industry standard for safety testing with use on vehicle barrier and sled testing and in anthropomorphic test dummies, and the 7264C-HR, maintains this legacy of ENDEVCO’s line of piezoresistive crash sensors.

 

The 7264C-HR device will provide for accurate measurement of all frequencies of interest without being affected by structure-borne resonances that could impose errors on the signal. By redesigning the base sensor the new unit will have a much higher fundamental frequency, providing unparalleled measurement accuracy.

 

Advanced materials being used in today’s vehicles and sensor mountings can resonate near the sensor’s fundamental frequency during a crash test. In these cases the output data can show a significant shift, resembling “saturation” during the first 15 milliseconds of the test. By creating a sensor that is not excited by resonances that may exist in the structure, ENDEVCO solves this problem, giving the truest measurement of the test situation.

 

Other methods that attempt to deal with this issue only “muddy” the data by inducing phase shifts. The resonance of those sensors is still excited and the output is still adversely affected, providing inaccuracies that may not be tolerable. The new ENDEVCO unit will provide the truest data throughout the entire test range.

 

Founded in 1947, Endevco Corporation has grown from a small research and development firm to an International corporation supporting customers with a global network of manufacturing, research facilities, sales offices and field engineers. Headquartered in San Juan Capistrano, CA, Endevco is the world’s leading designer and manufacturer of dynamic instrumentation for vibration, shock and pressure measurements.
