Six-Degree-of-Freedom Sensors to More Accurately Characterize Motion

Angular rate sensors measure relative rotational motion directly and provide an output in degrees per second. This measurement of angular velocity offers great improvement over the previous method of using three accelerometers and doing complex calculations. Multiple ranges are provided to enable measurement of slow or fast moving events.

Inertial Sensor Applications:

  • Vehicle dynamics
  • Automotive rollover
  • Whiplash
  • Aircraft flight testing
  • Spacecraft and satellite
  • Motion studies

Model 7360A - 6 Degrees of Freedom Sensor

The Endevco Model 7360A is a six-degrees of freedom (6DOF) sensor that features three DC accelerometers and three angular rate sensors packaged in a compact enclosure. This 6DOF sensor is designed specifically for automotive safety testing, aerospace testing and other testing in harsh shock and vibration environments requiring accurate measurement of accelerations and angular velocity. The 7360A 6DOF sensor features various accelerating ranges including ±2, ±10, ±50, ±200, ±500g and angular rate ranges including ±100, ±500, ±1500, ±8000, ±12000 and ±18000 deg/sec, and provides full scale voltage output of ±2Vpk.
