Overview

The B05Y31 is a compact three-axis IEPE accelerometer built on a piezoelectric ceramic shear structure. With 50 mV/g sensitivity and a ±100 g range it is a high-sensitivity model in the BXXY31 family for low-level vibration where signal-to-noise matters more than g range. Typical uses include structural and modal testing, vehicle body and cabin NVH, machinery vibration monitoring and low-amplitude R&D measurements.

Built-in low-impedance IEPE electronics deliver low noise and a wide-bandwidth response, and high-quality ceramics ensure long-term stability. The 12.2 mm cube titanium-alloy housing is laser welded to IP68, each axis has its own M2.5 mounting hole for improved coupling and calibration, and insulating mounting hardware is included as standard.

Why engineers choose the B05Y31

Shear-mode piezoceramic

High-quality piezoelectric ceramic in a shear structure gives a wide-band response with 1% non-linearity and long-term stability for years of accurate measurement.

Built-in IEPE electronics

Integrated low-impedance circuit with 2–20 mA constant-current excitation. Spectral noise of 8 µg/√Hz at 100 Hz and 0.0002 g rms broadband resolution.

Rugged titanium cube

Laser-welded titanium housing sealed to IP68, rated to 800 g rms vibration and 2,000 g pk shock. M2.5 mounting holes on every axis and an isolated mounting plate as standard.

Typical applications

  • Automotive NVH testing
  • Modal and structural vibration analysis
  • HASS / HALT and reliability screening
  • Electronic component and PCB validation
  • General vibration monitoring
  • General-purpose triaxial vibration measurement
