B09Y35

The B09Y35 is an impact-resistant, high-sensitivity three-axis IEPE accelerometer built on a piezoelectric ceramic shear sensing element with a wide-bandwidth response and a low-noise circuit optimized for low vibration amplitudes. With 500 mV/g sensitivity and a ±10 g range it is the 500 mV/g, ±10 g member of the family with a 5 kHz bandwidth and the highest shock survivability, for structural work where the sensor may see rough handling or impacts. Typical uses include bridge and building vibration, foundation and ground response, modal testing of large structures and monitoring on machinery subject to impacts.

Shape-memory alloy fasteners and a special structural design extend shock survivability well beyond standard fasteners, to 5,000 g pk, so a dropped or knocked sensor keeps its calibration. The built-in low-impedance circuit gives a good low-frequency response with a ≥ 2 s discharge time constant, and the laser-welded titanium-alloy 19.7 mm cube weighs 37 g, carries an M2.5 thread on each axis for coupling and calibration, and ships with an isolated mounting base as standard.

High sensitivity, low noise

500 mV/g output with spectral noise of 3.8 / 1.4 / 0.6 µg/√Hz at 10 / 100 / 1000 Hz and 0.00002 g rms broadband resolution, so the micro-g amplitudes of buildings, bridges and foundations come through clearly above the noise floor.

Survives rough handling

Shape-memory alloy fasteners with a special structural design carry the sensing element through 5,000 g pk shock and 3,000 g rms vibration without damage, far beyond what a high-sensitivity sensor with standard fasteners tolerates on site.

Three axes, one mounting point

Simultaneous X, Y and Z from a single 19.7 mm cube with ≤ 5% transverse sensitivity and a 1/4-28 4-pin connector for one four-core cable. Response from 0.5 Hz to 5 kHz (±5%) with resonance ≥ 32 kHz, M5 stud mount (10-32 optional) and the H02C10 isolated cube base included.
