B03B10

The B03B10 is a miniature uniaxial IEPE accelerometer with a highly integrated built-in impedance converter that turns the piezoelectric charge signal into a low-impedance voltage output, with excellent long-term stability and repeatability and a high-frequency response. With 20 mV/g sensitivity and a ±250 g range it is the mid-range model in the family, with ±250 g balancing range and resolution for everyday vibration work. Typical uses include modal analysis, vibration control, automotive NVH and general vibration measurement on light structures.

The built-in IEPE circuit runs from any 2–20 mA constant-current source with an 8–12 V bias. The laser-welded titanium-alloy 18.1 × 14.2 × 10 mm housing weighs just 6 g and is sealed to IP68, and a ⌀4.1 mm central through-hole lets it be bolted down with the supplied M4 screw and washer at any orientation, so the M5 side (10-32 opt.) connector can be pointed wherever the cable needs to go.

360° through-hole mount

A ⌀4.1 mm central through-hole takes an M4 screw (supplied with washer) or an M5 stud base, so the B03B10 bolts down at any rotation and the side connector can face the cable run. Mounting torque 3.0 N·m, mounting base H03B01.

Small and light

At 6 g and 18.1 × 14.2 × 10 mm, the B03B10 adds very little mass to light structures and fits where full-size sensors cannot, while the stiff through-hole mount keeps the response flat with a resonance ≥ 40 kHz.

Built-in IEPE electronics

Shear-mode piezoceramic with a highly integrated impedance converter: ±5% response from 1 Hz to 10 kHz (±10% over 0.5 – 12k Hz), spectral noise of 20 µg/√Hz at 100 Hz, 0.0005 g rms broadband resolution, rated to 2,000 g rms vibration and 5,000 g pk shock.
