Measurement Specialties, Inc. (NASDAQ: MEAS) new Model 7131A is a miniature triaxial IEPE accelerometer specifically designed for NVH, engine vibration, road response, modal analysis, structural testing, ride handling and flight testing. Available in ±50g to ±2000g dynamic ranges, this rugged accelerometer features a hermetically sealed titanium construction with a 4-pin Microtech connector interface. It incorporates stable piezo-ceramic crystals in annular shear mode which provide a flat frequency response up to >10kHz.

The Model 7131A features stable operating performance over an operating range of -55°C through +125°C with excellent linearity of ±1% (FSO). Operating from 18 to 30Vdc, this device provides a ±5Vdc output with an 8 - 12Vdc bias voltage. Excitation current is 2-10mA. The 7131A is case grounded and adhesively mounted for ease of installation.

Each unit is shipped with an NIST traceable amplitude calibration certificate. A 4-pin 1/4-28 to 3x BNC cable assembly (315) is offered as an accessory as is the Model 161A 4-Channel PE & IEPE Signal Conditioner.
