B02A92

The B02A92 is a high-frequency uniaxial IEPE accelerometer built on a piezoelectric ceramic shear structure with a flat response to 20 kHz within ±5% and a resonance above 50 kHz. With 10 mV/g sensitivity and a ±500 g range it is built for vibration testing on high-speed rotating equipment, where bearing, gear-mesh and blade-pass frequencies sit well beyond the reach of general-purpose sensors. Typical uses include high-speed magnetic-levitation bearings, ultra-high-speed motors, bearing and gearbox diagnostics and rocket-engine ignition testing.

Low transverse sensitivity and a low thermal transient response keep the signal clean, and shape-memory alloy fasteners give a stable, reliable assembly. The HEX 13.1 × 25 mm laser-welded stainless-steel housing is sealed to IP68 with a top connector and an M5 mounting thread at the base, with 10-32 connector and thread versions available.

Flat to 20 kHz

Shear-mode ceramics with a resonance ≥ 50 kHz give a ±5% response from 1 Hz to 20 kHz (±10% to 21 kHz), so high-order bearing, gear-mesh and blade-pass harmonics are measured, not attenuated.

Built-in IEPE electronics

Miniature low-impedance circuit with 2–20 mA constant-current excitation and 8–12 V bias. Spectral noise of 24 µg/√Hz at 100 Hz and 0.001 g rms broadband resolution drive long cables into any IEPE-compatible DAQ.

Rugged stainless housing

Laser-welded HEX 13.1 × 25 mm stainless-steel housing sealed to IP68, weighing 14 g and rated to 1,200 g rms vibration and 3,500 g pk shock. Shape-memory alloy fasteners, top connector with M5 or 10-32 options.
