C00CG1

The C00CG1 is a charge-mode (PE) ground-isolated uniaxial shock accelerometer built on a unique piezoelectric ceramic shear structure with reduced base strain and transverse sensitivity and a resonance above 65 kHz. With 1 pC/g charge sensitivity and a ±25,000 g range it is the ±25,000 g integral-cable member of the family for severe shock and impact testing. Typical uses include drop-table and impact testing, blast shock testing, munitions and ordnance qualification and package drop testing.

With no built-in electronics the sensor works 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, shape-memory alloy fasteners keep the shear structure stable through repeated impacts, and a unique double-shielded construction isolates the signal ground (≥ 10⁸ Ω) so multi-channel shock tests on conductive fixtures stay free of ground loops. The laser-welded 17-4 stainless-steel housing weighs 12 g and mounts on an integrated one-piece male screw, configurable as M5, M6 × 0.75 or 10-32, with an integral high-temperature cable exiting from the top or side.

Built for extreme shock

Shear-mode ceramics with a resonance ≥ 65 kHz handle events to 35,000 g pk. Reduced base strain and ≤ 5% transverse sensitivity keep the signal honest under severe impacts, with a ±10% response over 5 – 12k Hz. Non-linearity 5%.

Ground isolated, charge output

Double-shielded construction gives ≥ 10⁸ Ω isolation between signal ground and the mounting surface, and with no internal electronics there is nothing to saturate or overheat: 300 pF capacitance and ≥ 10¹¹ Ω insulation resistance into any charge amplifier, to +160 °C.

Integrated screw, integral cable

One-piece integrated male mounting screw with shape-memory alloy fasteners, configurable as M5, M6 × 0.75 or 10-32, torqued to 3.0 – 3.5 N·m. Integral high-temperature cable in a top-exit (HEX 11 × 27.1 mm) or side-exit (HEX 11 × 20.4 mm) housing.
