Available now from Metromatics , the Dytran Instruments model 3091A IEPE piezoelectric accelerometer is designed for use in Health and Usage Monitoring Systems (HUMS) and Active Vibration Control (AVC) of commercial and military aircraft.

The Dytran Instruments model 3091A IEPE piezoelectric accelerometer is offered with a range of 500g, 100 mV/g sensitivity and an upper frequency response of 1,000 Hz (±5%).

As an IEPE sensor, the model 3091A piezoelectric accelerometer features built-in electronics, eliminating the need for an external charge amplifier and converter. The design also features a quartz sensing element operating in shear mode, all of which is packaged in a rugged stainless steel housing with a radial 3-pin "Mighty Mouse" connector.

Another distinguishing feature of the model 3091A IEPE piezoelectric accelerometer is that the sensor element is incorporated directly into the mounting bracket, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets. This distinctive design also offers reduced mass, as compared to conventional sensors and mounting brackets.

The Dytran Instruments model 3091A IEPE piezoelectric accelerometer is hermetically sealed for use in dirty and high-humidity environments, and case isolated to avoid EMI/ground loop interference.

With its durability, compact size and mounting characteristics, the Dytran Instruments model 3091A IEPE piezoelectric accelerometer is ideal for high-frequency aircraft/airframe vibration measurements, Rotor Track and Balance (RTB) and transmission vibration measurements.

Key features of the model 3091A piezoelectric accelerometer include:

  • bracket style
  • "Mighty Mouse" connector/removable cable 
  • eliminates need for separate mounting bracket 
  • multiple sense directions available 
  • case isolated 
  • IEPE
Potential applications for the model 3091A IEPE piezoelectric accelerometer include:
  • high-frequency aircraft/airframe vibration measurements 
  • Health and Usage Monitoring Systems (HUMS)
  • Rotor, Track and Balance (RTB) 
  • transmission vibration measurements.
