C00BM1

The C00BM1 is a charge-mode (PE) miniature accelerometer built on a piezoelectric ceramic shear structure with a wide-bandwidth frequency response and excellent long-term stability and repeatability. With 1 pC/g charge sensitivity and a ±5,000 g range it is the smallest and highest-range member of the family, a 1 g teardrop rated to +250 °C and 10,000 g pk for shock and high-frequency work on tiny hot parts. Typical uses include shock and high-frequency measurement on small components, PCB and electronics testing at high temperature, turbocharger and exhaust parts and structures where a heavier sensor would load the test article.

With no built-in electronics the sensor works from −50 °C to +250 °C and pairs with any charge amplifier, which sets the low-frequency limit of the system. Shape-memory alloy fasteners keep the shear structure stable and reliable, and the laser-welded titanium-alloy housing measures just 15.7 × 8.5 × 5.1 mm and weighs 1 g, so it adds almost no mass to small or light test articles. It mounts with adhesive and carries an M3 side connector.

Minimal mass loading

At 1 g and 15.7 × 8.5 × 5.1 mm, the C00BM1 barely changes the response of PCBs, small components and light structures, so what you measure is the structure, not the sensor. Adhesive mounting for fast installation on any flat surface.

Charge mode, +250 °C

No internal electronics means nothing to overheat: the C00BM1 runs continuously at +250 °C and pairs with any charge amplifier or charge-input DAQ, with 150 pF capacitance and ≥ 10¹¹ Ω insulation resistance for a clean, stable charge signal.

Shear-mode piezoceramic

Shear structure with shape-memory alloy fasteners gives a ±5% response from 3 Hz to 10 kHz (±10% over 2 – 12k Hz) with resonance ≥ 50 kHz, 1% non-linearity and ≤ 5% transverse sensitivity, rated to 10,000 g pk shock.
