Available now from Metromatics , the Dytran Instruments model 3302A biaxial IEPE accelerometer is designed to provide dynamic vibration monitoring within Active Vibration Control (AVC) applications typically found on commercial and military aircraft.

Utilising an innovative biaxial design, the Dytran model 3302A piezoelectric accelerometer incorporates the mounting bracket and sensing elements in a single package. This feature facilitates improved sensor performance while eliminating the costs associated with employing separate accelerometers and mounting brackets.

The biaxial design also offers reduced mass compared to conventional sensors and mounting brackets.

As an IEPE sensor, the model 3302A biaxial piezoelectric accelerometer features built-in electronics, eliminating the need for an external charge amplifier and converter.

The design of the model 3302A accelerometer features quartz sensing elements, operating in shear mode, and is packaged in a compact stainless steel housing measuring 2.67cm x 3.01cm x 1.22cm.

Weighing just 30g the Dytran model 3302A biaxial piezoelectric accelerometer utilises a 5/16-28 3-pin radial connector and offers vibration measurement capabilities up to 500g range, with a 10 mV/g sensitivity.

The units are hermetically sealed for reliable operation within high-humidity and dirty environments as well as case isolated to avoid electromagnetic or group loop interference.

With its durability, unique bracket-style mount and performance characteristics, the Dytran model 3302A biaxial piezoelectric accelerometer is ideal for high-reliability aircraft/airframe vibration measurements, Health & Usage Monitoring Systems (HUMS), Rotor Track & Balance (RTB) and transmission vibration monitoring.

Key Features of these accelerometers include:

  • integral bracket-style mounting configuration
  • 500g range 
  • 10 mV/g sensitivity 
  • 5/16-28 3-pin radial connector 
  • 30g weight
  • stainless steel
  • hermetically sealed
  • case isolated
  • IEPE.
