Airborne Accelerometer Sensor Model 3091A

The Dytran model 3091A is an innovative IEPE piezoelectric accelerometer with a 10 mV/g sensitivity, designed for use in Health and Usage Monitoring Systems (HUMS) as well as Active Vibration Control (AVC) of commercial and military aircraft. Featuring a radial 3–pin "Mighty Mouse™" connector with 5/16–28 thread, the Dytran model 3091A is hermetically sealed for use in high humidity environments, and case isolated to avoid EMI/ground loop interference.

The distinguishing feature of model 3091A is the Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets. This unique design also offers reduced mass, as compared to conventional sensors and mounting brackets. The miniature accelerometer is mounted within the bracket at the point where the cable and bracket are joined.
