B06B05

The B06B05 is a reference-grade uniaxial IEPE accelerometer built on a piezoelectric ceramic shear sensing element with a wide-bandwidth frequency response, low transverse sensitivity and low thermal transient response, with the excellent year-to-year stability needed of a calibration transfer standard. With 100 mV/g sensitivity and a ±50 g range it is the high-sensitivity compact reference in the family, with a 2.4 µg/√Hz noise floor for low-level comparison calibration. Typical uses include back-to-back comparison calibration of general-purpose and high-sensitivity accelerometers, low-level shaker verification, standard bench tests and laboratory reference measurements.

The back-to-back design carries an M5 × 4.6 (10-32 opt.) mounting thread on both the upper and lower faces, so the sensor under test bolts directly onto the reference on the shaker and both see the same motion. The built-in high-temperature-rated low-impedance circuit gives low output noise and stable sensitivity over temperature from any 2–20 mA IEPE source. The laser-welded stainless-steel 17.2 × 17.2 × 18.7 mm housing weighs 32 g, is sealed to IP68 and carries a side M5 (10-32 opt.) connector.

Built as a reference

Shear sensing element with ≤ 2% transverse sensitivity, 1% non-linearity and excellent annual stability, so the reference adds as little uncertainty as possible to a comparison calibration. ±5% response from 1 Hz to 8 kHz (±10% over 0.5 – 10k Hz) with resonance ≥ 40 kHz.

Back-to-back mounting

M5 × 4.6 (10-32 opt.) thread on the base for the shaker and the same thread on top for the sensor under test, so reference and test sensor are rigidly coupled and move together well beyond the calibration band. Mounting torque 3.0 N·m. Side M5 (10-32 opt.) connector keeps the cable clear of the stack.

Low noise, stable over temperature

Built-in high-temperature-rated IEPE circuit with 2–20 mA excitation and 8–12 V bias, spectral noise of 2.4 µg/√Hz at 100 Hz and 0.0001 g rms broadband resolution, rated to 400 g rms vibration and 1,000 g pk shock, −50 to +80 °C.
