C08A01

The C08A01 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 300 pC/g charge sensitivity and a ±200 g range it is the mid-range member of the family, with 300 pC/g and a ±200 g range plus case isolation for multi-channel work on conductive structures. Typical uses include modal analysis, vibration control, high-temperature structural and machinery monitoring and multi-channel tests where ground loops are a concern.

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, and a ≥ 10⁸ Ω case isolation keeps ground loops out of multi-channel installations. The laser-welded HEX 19.1 × 34.3 mm stainless-steel housing is sealed to IP68 with a top M5 connector and an M5 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 C08A01 runs continuously at +160 °C and pairs with any charge amplifier or charge-input DAQ, with 2,300 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 3 kHz (±10% over 0.3 – 4k Hz) with resonance ≥ 16 kHz, 1% non-linearity and ≤ 5% transverse sensitivity. Case isolated to ≥ 10⁸ Ω.

Rugged stainless housing

Laser-welded HEX 19.1 × 34.3 mm stainless-steel housing sealed to IP68, weighing 54.5 g and rated to 500 g rms vibration and 800 g pk shock. Top connector with M5 or 10-32 options and an M5 × 5.1 stud mount at 3.0 N·m.
