B10A01

The B10A01 is a low-frequency uniaxial IEPE accelerometer built on a piezoelectric ceramic shear sensing element with a dedicated low-frequency, low-impedance circuit. With 1,000 mV/g sensitivity, a ±5 g range and a ±5% response from 0.06 Hz, it is the ultra-low-frequency, case-isolated member of the family, reaching down to 0.06 Hz with 1,000 mV/g and the lowest noise floor. Typical uses include bridge, dam and high-rise building monitoring, ground and foundation vibration, wind-turbine tower sway and seismic and micro-vibration measurement.

High-grade piezoelectric ceramics deliver long-term output stability, and the low-frequency circuit gives low output noise (0.24 µg/√Hz at 100 Hz) and good signal resolution at low amplitudes, with ≥ 10⁸ Ω case isolation to keep ground loops out of long cable runs on structures. The laser-welded HEX 19.1 × 34.3 mm stainless-steel housing is sealed to IP68 with a top M5 connector and an M5 stud thread on the base, with 10-32 connector and thread versions available.

Response down to 0.06 Hz

A dedicated low-frequency IEPE circuit with a ≥ 10 s discharge time constant holds the ±5% response from 0.06 Hz to 2 kHz, so slow structural sway, foundation motion and low-speed machinery are measured, not filtered away.

Low-noise IEPE electronics

Low-impedance circuit with 2–20 mA constant-current excitation and 8–12 V bias. Spectral noise of 0.6 / 0.24 / 0.16 µg/√Hz at 10 / 100 / 1000 Hz and 0.00001 g rms broadband resolution resolve the tiny amplitudes typical of civil and structural work. Case isolated to ≥ 10⁸ Ω.

Rugged sealed housing

Shear sensing element with low base-strain sensitivity in a laser-welded HEX 19.1 × 34.3 mm stainless-steel housing sealed to IP68, weighing 60 g and rated to 40 g rms vibration and 100 g pk shock. Top connector with M5 or 10-32 options.
