B10A03

The B10A03 is an ultra-low-noise, high-sensitivity uniaxial IEPE accelerometer designed specifically for low-frequency, low-amplitude measurement. A compact high-sensitivity shear sensing element and a dedicated low-noise ASIC give a high signal-to-noise ratio at low frequencies, and with 1,000 mV/g sensitivity and a ±5 g range it is the 1,000 mV/g, ±5 g member of the family, reaching down to 0.1 Hz with 3 µg rms broadband resolution for very low-level, low-frequency vibration. Typical uses include bridge, building and dam monitoring, foundation and ground-borne vibration, micro-vibration surveys of precision facilities and seismic-grade structural measurement.

Spectral noise is just 0.1 µg/√Hz at 100 Hz and 0.3 µg/√Hz at 10 Hz, with a ≥ 10 s discharge time constant holding the ±5% response down to 0.1 Hz. The laser-welded ⌀25 × 31.9 mm stainless-steel housing is sealed to IP68 with a top M5 connector (10-32 optional) and a 10-32 stud thread on the base.

Ultra-low noise floor

A dedicated low-noise ASIC and high-sensitivity element give spectral noise of 0.3 / 0.1 / 0.04 µg/√Hz at 10 / 100 / 1000 Hz and 0.000003 g rms broadband resolution, so sub-micro-g motion in buildings, foundations and precision facilities is resolved cleanly.

Built for low frequency

1,000 mV/g output with a ≥ 10 s discharge time constant and a ±5% response from 0.1 Hz, plus 0.05 – 4k Hz at ±3 dB. IEPE-compatible two-wire interface with 2–20 mA excitation and 8–12 V bias runs into any standard DAQ or monitoring system.

Sealed stainless housing

Laser-welded ⌀25 × 31.9 mm stainless-steel housing sealed to IP68, weighing 135 g, rated to 40 g rms vibration and 100 g pk shock and −40 to +85 °C. Top connector with M5 or 10-32 options and a 10-32 × 4 stud mount at 3.0 N·m.
