B06B06

The B06B06 is a low-frequency uniaxial IEPE accelerometer built on a piezoelectric ceramic shear sensing element with a dedicated low-frequency, low-impedance circuit. With 100 mV/g sensitivity, a ±50 g range and a ±5% response from 0.1 Hz, it is the wide-range member of the family, reaching down to 0.1 Hz with a ±50 g range and 6 kHz bandwidth for general low-frequency work. Typical uses include bridge and building vibration, floor and foundation measurements, low-speed rotating machinery and general low-frequency structural monitoring.

High-grade piezoelectric ceramics deliver long-term output stability, and the low-frequency circuit gives low output noise (2.4 µg/√Hz at 100 Hz) and good signal resolution at low amplitudes. The laser-welded HEX 16.1 × 19.1 mm stainless-steel housing is sealed to IP68 with a low-profile side M5 connector and an M5 stud thread on the base, with 10-32 connector and thread versions available.

Response down to 0.1 Hz

A dedicated low-frequency IEPE circuit with a ≤ 1 s discharge time constant holds the ±5% response from 0.1 Hz to 6 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 6 / 2.4 / 1.6 µg/√Hz at 10 / 100 / 1000 Hz and 0.0001 g rms broadband resolution resolve the tiny amplitudes typical of civil and structural work.

Rugged sealed housing

Shear sensing element with low base-strain sensitivity in a laser-welded HEX 16.1 × 19.1 mm stainless-steel housing sealed to IP68, weighing 24 g and rated to 400 g rms vibration and 1,000 g pk shock. Side connector with M5 or 10-32 options.
