C01BT2

The C01BT2 is a charge-mode (PE) ultra-high-temperature accelerometer built on ultra-high-temperature piezoelectric ceramics with an ultra-low sensitivity temperature coefficient and high impedance maintained right up to 500 °C. With 5 pC/g charge sensitivity and a ±1,000 g range it is the higher-range member of the family, with ±1,000 g for higher-level vibration on the hottest parts of an engine or turbine. Typical uses include turbine and afterburner vibration, engine and exhaust-manifold testing, high-temperature industrial monitoring and combustion rigs to 500 °C.

With no built-in electronics the sensor works from −55 °C to +500 °C and pairs with any charge amplifier, which sets the low-frequency limit of the system. A special high-temperature nickel-based alloy housing and matched piezoelectric material keep temperature drift low, and a special coaxial 10-32 connector with the signal ground isolated from the housing (≥ 10⁹ Ω) keeps long cable runs from hot zones free of ground loops. The laser-welded HEX 15.8 × 26 mm housing weighs 28 g, is sealed to IP68, screws down on an M5 (10-32 opt.) mounting hole torqued to 3.0 N·m, and takes standard high-temperature metal cables on a side-exit connector.

Rated to 500 °C

Ultra-high-temperature piezoceramics with an ultra-low sensitivity temperature coefficient keep the C01BT2 reading accurately from −55 °C to +500 °C, with ≥ 10⁹ Ω insulation resistance held at temperature and 300 pF capacitance into any charge amplifier. No internal electronics, so nothing to fail in the heat.

Isolated coaxial connector

Special coaxial 10-32 connector with the signal ground isolated from the housing (≥ 10⁹ Ω), so the sensor bolts straight to hot conductive structures without ground loops and takes standard high-temperature metal cables. ±5% response over 10 – 6k Hz (±10% over 1 – 8k Hz), resonance ≥ 25 kHz, ≤ 5% transverse sensitivity.

Compact hex, M5 mount

Laser-welded nickel-based alloy HEX 15.8 × 26 mm housing weighing 28 g, sealed to IP68 and rated to 1,000 g rms vibration and 3,000 g pk shock. M5 (10-32 opt.) mounting hole torqued to 3.0 N·m, with a side connector for a low profile on hot casings.
