C04A60

The C04A60 is a charge-mode (PE) 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 ±1,500 g range it is the most sensitive member of the family, with 30 pC/g and a ±1,500 g range for lower-level vibration in hot or cold environments. Typical uses include low-level vibration control in thermal chambers, ESS on assemblies and modules, high-temperature machinery monitoring and long-duration environmental qualification.

With no built-in electronics the sensor works from −70 °C to +250 °C and pairs with any charge amplifier, which sets the low-frequency limit of the system. High-quality ceramics ensure long-term stability, and shape-memory alloy fasteners keep the shear structure stable and reliable through repeated thermal cycling. The laser-welded stainless-steel HEX 13.1 × 25 mm housing weighs 17 g, screws down on an M5 (10-32 opt.) stud and carries a top M5 (10-32 opt.) connector. For low-temperature use, reduce the measurement range by a factor of ten.

−70 to +250 °C, charge output

No internal electronics means nothing to freeze or overheat: the C04A60 runs continuously anywhere from −70 °C to +250 °C with a low sensitivity temperature response, and pairs with any charge amplifier or charge-input DAQ, with 1,300 pF capacitance and ≥ 10¹¹ Ω insulation resistance.

Wide, flat bandwidth

Shear-mode ceramics with shape-memory alloy fasteners give a ±5% response from 0.5 Hz to 7 kHz (±10% over 0.3 – 9k Hz) with resonance ≥ 50 kHz, 1% non-linearity and ≤ 5% transverse sensitivity, rated to 3,000 g rms vibration and 3,500 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.
