Endevco's 7264D crash accelerometer

Endevco Corp. has introduced its 7264D high resonance crash accelerometer for automotive safety testing applications including vehicle barrier and sled testing and anthropomorphic test dummies.

The 7264D device is based on the 7264B and C series of transducers and provides an extended "flat" frequency range and resonant frequency of more than 40,000Hz. This resonance characteristic is said to solve a typical problem found in automotive crash test events that often induce resonances in a sensor during extremely short duration shock pulses.

In vibration and shock measurement, the 7264D is also said to deliver the widest possible frequency range without inducing signal phase shifts found in other competitive products which can "muddy" the data and result in hidden inaccuracies that may render expensive test data useless, said the company. The accelerometer is J211 compliant; maintains the un-damped characteristics desired by test engineers, and provides data records that are true and accurate over an extended frequency range.

Other features include true ratiometric operation over a wide range of excitation voltage, optional connectors, multiple ID chip configurations, industry standard cable lengths, and mounting accessories.
