B05Y94

The B05Y94 is a high-temperature three-axis IEPE accelerometer built on a piezoelectric ceramic shear structure with an internal high-temperature, low-impedance circuit rated to +160 °C. With 50 mV/g sensitivity and a ±100 g range it is a high-sensitivity model in the family for low-level triaxial vibration at elevated temperatures where signal-to-noise matters more than g range. Typical uses include NVH on hot components, modal and structural analysis, condition monitoring on hot machinery and low-amplitude environmental testing.

Low transverse sensitivity and a low thermal transient response keep the three channels clean through thermal cycling, and the lightweight 13.5 mm titanium-alloy cube is laser welded to IP68. Each axis has its own M2.5 calibration and mounting hole for easy installation and calibration, and an insulated mounting assembly ships as standard.

Rated to +160 °C

A built-in high-temperature circuit and low-drift piezoelectric material keep all three channels stable from −50 °C right up to +160 °C, with a low thermal transient response for clean data on hot surfaces and through thermal cycling.

Three axes, one mounting point

Simultaneous X, Y and Z measurement from a single cube with ≤ 5% transverse sensitivity. Built-in IEPE electronics with 2–20 mA excitation and 8–14 V bias; spectral noise of 4.8 µg/√Hz at 100 Hz.

Lightweight titanium cube

Laser-welded 13.5 mm titanium-alloy cube sealed to IP68, weighing 8.2 g and rated to 800 g rms vibration and 2,000 g pk shock. M2.5 holes on every axis, adhesive mounting and an insulated mounting base as standard.
