C02B02

The C02B02 is a charge-mode (PE) uniaxial environmental test accelerometer built on a piezoelectric ceramic shear structure with a wide-bandwidth frequency response and a low sensitivity temperature response. With 10 pC/g charge sensitivity and a ±500 g range it is the widest-bandwidth member of the family, with 10 pC/g, a ±500 g range and a ±5% response to 10 kHz for higher-level and higher-frequency work. Typical uses include vibration control and shaker testing in thermal chambers, modal analysis on stiff structures, engine and machinery vibration and general monitoring at temperature extremes.

With no built-in electronics the sensor works from −70 °C to +160 °C and pairs with any charge amplifier or charge-input controller, which sets the low-frequency limit of the system. High-quality ceramics ensure long-term stability through repeated thermal cycling. The laser-welded stainless-steel HEX 13.1 × 18.8 mm housing weighs 14.5 g, is sealed to IP68, screws down on an M5 (10-32 opt.) stud and carries a side M5 (10-32 opt.) connector.

−70 to +160 °C, charge output

No internal electronics means nothing to freeze or overheat: the C02B02 runs continuously anywhere from −70 °C to +160 °C with a low sensitivity temperature response, and pairs with any charge amplifier or charge-input DAQ, with 1,250 pF capacitance and ≥ 10¹¹ Ω insulation resistance.

Wide, flat bandwidth

Shear-mode ceramics give a ±5% response from 0.5 Hz to 10 kHz (±10% over 0.3 – 11k Hz) with resonance ≥ 50 kHz, 1% non-linearity and ≤ 5% transverse sensitivity, rated to 650 g rms vibration and 650 g pk shock.

Rugged stainless housing

Laser-welded stainless-steel HEX 13.1 × 18.8 mm housing sealed to IP68 and weighing 14.5 g. M5 × 3.7 (10-32 opt.) mounting stud torqued to 3.0 N·m, with a side M5 (10-32 opt.) connector for a low profile in tight spaces.
