Meggitt Sensing Systems introduces optimally gas-damped auto crash sensor eliminating irrelevant frequency content

IRVINE, Calif., USA – Sept. 12, 2016 – Meggitt Sensing Systems, a Meggitt division and leader in sensing and monitoring systems for extreme environments, has launched an optimally gas-damped accelerometer for automotive safety testing.  Target applications include pedestrian safety, military vehicle and sled testing.

The new Endevco model 7264H, which is small in size and mass, eliminates irrelevant frequency content generated by breaking glass and metal-to-metal impact and, unlike fluid-damped sensors, performs consistently over temperatures ranging from – 18°C to + 66°C (0°F to + 150°F).

Utilizing an innovative MEMS design, the 7264H has a much wider frequency measurement range compared to conventional fluid-damped sensors.  This new accelerometer approaches the 0.7 of critical damping which is ideal for dynamic testing.

Key features

  • Frequency response flat from DC to 3,500Hz
  • Full scale range of 1000g
  • 50 to .85 damping ratio
  • 10,000g shock capacity
  • 1.4g weight

The 7264H has a two-active-arm, full-bridge circuit with fixed completion resistors to facilitate shunt calibration. Full-scale output is 200 mV nominal with 10 Vdc excitation for excellent signal-to-noise performance. The 7264H comes standard with 2, 5 and 10 volt calibration data.

The 7264H is in stock. Demo units are available upon request.
