B09Y54T

The B09Y54T is an industrial-grade dual-axis low-frequency IEPE accelerometer with a built-in PT1000 temperature sensor, so one unit and one M12 cable deliver two vibration axes and temperature from each monitoring point. Built on a piezoelectric ceramic shear sensing element with a wide-bandwidth response, it has 500 mV/g sensitivity and a ±10 g range on both axes and is the ±10 g member of the pair, for two-axis monitoring of slow-turning machinery and structures at moderate vibration levels. Typical uses include wind-turbine main bearings, gearbox input stages and tower monitoring, rail bogie and axle-box monitoring, and construction and mining machinery drivetrains.

High-grade piezoelectric ceramics deliver long-term output stability. The two-wire IEPE circuit on each axis takes constant-current excitation and returns a low-impedance voltage signal on the same pair, while a double-shielded construction isolates the signal ground from the housing (≥ 10⁸ Ω) to keep ground loops out of long plant cable runs. The laser-welded 50 × 48 × 25 mm stainless-steel housing is sealed to IP68 for corrosion resistance, with an M12 5-pin connector and a ⌀5.2 mm through-hole or M5 stud mount, and ships with an isolated mounting plate.

Two axes plus temperature, one cable

Simultaneous measurement on two perpendicular axes with ≤ 5% transverse sensitivity, plus a built-in PT1000 RTD (±(0.7 + 0.005·|t|) °C over −40 to +125 °C) on the same M12 5-pin connector, so radial and axial vibration and bearing temperature all ride on one cable.

Isolated industrial build

Double-shielded construction isolates the signal ground from the housing (≥ 10⁸ Ω), and the laser-welded 50 × 48 × 25 mm stainless-steel housing is sealed to IP68 and rated to 400 g rms vibration and 1,000 g pk shock, for years of service on turbines, rail vehicles and heavy machinery.

Low-frequency, low-noise IEPE

Two-wire IEPE electronics with 2–20 mA excitation and 10–14 V bias hold a ±5% response from 0.3 Hz to 2 kHz (±3 dB from 0.1 Hz to 5 kHz) for slow-turning machinery, with spectral noise of 0.48 µg/√Hz at 100 Hz and 0.00002 g rms broadband resolution.
