C04B03

The C04B03 is a charge-mode (PE) uniaxial 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 ±1,000 g range it is a mid-range member of the family, with 30 pC/g, a ±1,000 g range and 7 kHz bandwidth for general charge-mode vibration work at high temperature. Typical uses include modal analysis, vibration control, high-temperature structural and machinery monitoring and general vibration measurement to +160 °C.

With no built-in electronics, the sensor works from −40 °C to +160 °C and pairs with any charge amplifier, which sets the low-frequency limit of the system. High-quality ceramics ensure long-term stability. The laser-welded HEX 13.1 × 18.8 mm stainless-steel housing weighs 17.3 g and is sealed to IP68, with a M5 side connector and an M5 × 3.7 (10-32 opt.) stud thread on the base, with 10-32 connector and thread versions available.

Charge mode, +160 °C

No internal electronics means nothing to overheat: the C04B03 runs continuously at +160 °C and pairs with any charge amplifier or charge-input DAQ, with 850 pF capacitance and ≥ 10¹¹ Ω insulation resistance for a clean, stable charge signal.

Shear-mode piezoceramic

Shear structure with low base-strain and temperature sensitivity gives a ±5% response from 0.5 Hz to 7 kHz (±10% over 0.3 – 9k Hz) with resonance ≥ 32 kHz, 1% non-linearity and ≤ 5% transverse sensitivity.

Rugged stainless housing

Laser-welded HEX 13.1 × 18.8 mm stainless-steel housing sealed to IP68, weighing just 17.3 g and rated to 2,000 g rms vibration and 2,500 g pk shock. Side connector and an M5 × 3.7 (10-32 opt.) stud mount at 3.0 N·m. M5 or 10-32 connector and thread options.
