Biaxial Accelerometer Designed for HUMS and AVC Applications

Biaxial Accelerometer Designed for HUMS and AVC Applications

Dytran has just released a new biaxial accelerometer designed for use in Health and Usage Monitoring Systems (HUMS) as well as Active Vibration Control (AVC) applications typically found on commercial and military aircraft.

Model 3232A1 is an innovative piezoelectric biaxial accelerometer incorporated into a mounting bracket. The accelerometer elements are mounted orthogonally within the bracket and are internally case isolated from the mounting surface. The unique integral mounting bracket design eliminates the cost associated with separate mounting brackets while improving sensor performance as well as reducing mass when compared to conventional separate sensors and mounting brackets.

This unit features a radial 3-pin "Mighty Mouse" connector with a 5/16-28 thread, and 10 mV/g sensitivity. The 3232A1 also features a case isolated design to avoid annoying ground loops and hermetic sealing for normal operation in moist and dirty environments. The 3232A series also includes model 3232A2 which has a sensitivity of 100 mV/g.

Key Features:

* Biaxial
* 10 mV/g sensitivity
* Threaded 3-pin "Mighty Mouse" connector
* Unique integral mounting bracket for cost savings and reduced mass
* 45 grams
* Hermetic
* Case isolated
* IEPE

Potential Applications:

* Health and Usage Monitoring Systems (HUMS)
* Active Vibration Control (AVC)
