Dytran Instruments 3315A high frequency IEPE accelerometer

Dytran Instruments has introduced model 3315A, a high frequency IEPE accelerometer designed for use in health and usage monitoring systems as well as active vibration control of commercial and military aircraft.

Offered with a 250 g range and 20 mV/g sensitivity, the instrument has an upper frequency response of 10,000 Hz. As an IEPE sensor, it features built-in electronics, eliminating the need for an external charge amplifier and converter.

Design features include low noise JFET electronics packaged in a compact, rugged, stainless steel housing with a radial 2-pin bayonet-style connector and 1/4-28 mounting stud.

It also features internal case ground isolation to avoid EMI/ground loop interference and hermetic sealing for operation in high-humidity and dirty environments. With its durability, compact size and mounting characteristics, it is suitable for high frequency aircraft/airframe vibration measurements, rotor track and balance and permanent or walk-around vibration monitoring of rotating machinery, including bearing noise measurements.
