B03BM1

The B03BM1 is a miniature teardrop uniaxial IEPE accelerometer with a built-in miniature impedance converter that conditions the piezoelectric charge signal to a low-impedance voltage output. With 20 mV/g sensitivity and a ±250 g range it is a wide-bandwidth mid-range member of the family, balancing range and noise for general vibration work in confined spaces. Typical uses include PCB vibration testing, ESS, component qualification and vibration measurements in confined spaces.

A highly integrated miniature circuit gives excellent long-term output stability and repeatability, and the laser-welded titanium-alloy teardrop housing keeps the whole sensor to 15.7 × 8.5 × 5.1 mm and 1.4 g for minimal mass loading on the test structure. The low-profile M3 side connector and adhesive base mount make it easy to install where space is tight.

Minimal mass loading

At 1.4 g and 15.7 × 8.5 × 5.1 mm, the B03BM1 barely changes the response of PCBs, small components and light structures, so what you measure is the structure, not the sensor.

Miniature built-in electronics

Built-in impedance converter with 2–20 mA constant-current excitation delivers a low-impedance IEPE output with spectral noise of 20 µg/√Hz at 100 Hz, 0.0005 g rms broadband resolution and excellent long-term stability and repeatability.

Laser-welded titanium teardrop

Laser-welded titanium-alloy teardrop housing sealed to IP68, rated to 1,200 g rms vibration and 3,000 g pk shock, with bandwidth to 10 kHz and resonance ≥ 38 kHz. Adhesive mount with an M3 side connector.
