C04A05

The C04A05 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 30 pC/g charge sensitivity and a ±150 g range it is the mid-sensitivity member of the family, with 30 pC/g and a ±150 g range in a compact 13.1 mm housing. Typical uses include vibration control and environmental testing in thermal chambers, modal analysis, structural 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 × 25 mm housing weighs 17 g, is sealed to IP68, screws down on an M5 (10-32 opt.) stud and carries a top M5 (10-32 opt.) connector.

−70 to +160 °C, charge output

No internal electronics means nothing to freeze or overheat: the C04A05 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 1,700 pF capacitance and ≥ 10¹¹ Ω insulation resistance.

Wide, flat bandwidth

Shear-mode ceramics give a ±5% response from 0.5 Hz to 7 kHz (±10% over 0.3 – 9k Hz) with resonance ≥ 38 kHz, 1% non-linearity and ≤ 5% transverse sensitivity, rated to 300 g rms vibration and 300 g pk shock.

Rugged stainless housing

Laser-welded stainless-steel HEX 13.1 × 25 mm housing sealed to IP68 and weighing 17 g. M5 × 3.7 (10-32 opt.) mounting stud torqued to 3.0 N·m, with a top M5 (10-32 opt.) connector for a straight cable exit.
