IRVINE, Calif. - June 7, 2018 - PRLog -- Meggitt Sensing Systems, a division of Meggitt PLC, has released the Model 7268D triaxial accelerometer for the World SID anthropomorphic test dummy. Following a recent breakthrough in MEMS design, this device features multi-mode gas damping to eliminate interference from unwanted ringing and provides a more accurate measurement.

This upgraded design also offers better survivability and signal-to-noise ratio compared to other sensors in the auto safety marketplace. The Endevco 7268D is a "drop-in" replacement for the undamped 7268C currently in use and provides superior performance while maintaining the same center of seismic mass - a feature that is vitally important for dummy installation.

The expanded cold and hot temperature range facilitates testing in a broader range of environments. In addition, the standard 5 and 10 V calibration ensures ease of system integration, as you can use the sensitivity and ZMO that match your desired input voltage for the best data accuracy.

Key features:
  • Multi-mode gas damping
  • 0.2 mV/g sensitivity
  • Rugged to 10,000 g shock
  • Supplied with 5 V and 10 V calibration
  • Wide operating temperature range (-40 to 100 °C)

The 7268D is SAE J211/J2570 compliant and meets or exceeds CE and RoHS standards. Each unit is shipped with a mounting screw and washer as well as a calibration certificate. Quality control is maintained through in-house fabrication of the MEMS sensor to final test with certified, in-house calibration systems.
