Dytran Instruments 3091A IEPE accelerometer

Dytran Instruments has introduced the model 3091A IEPE accelerometer, designed for use in health and usage monitoring systems and active vibration control of commercial and military aircraft.

The instrument is offered with a range of 500 g, 100 mV/g sensitivity and an upper frequency response of 1000 Hz (±5%). As an IEPE sensor, it has 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 and packaged in a rugged stainless steel housing with a radial three-pin ‘Mighty Mouse’ connector.

The sensor element is incorporated directly into the mounting bracket, facilitating improved performance while eliminating costs associated with separate mounting brackets. This distinctive design also offers reduced mass.

The 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 3091A is suitable for high-frequency aircraft/airframe vibration measurements, Rotor Track and Balance (RTB) and transmission vibration measurements.
