C05AG4

The C05AG4 is a charge-mode (PE) high-temperature accelerometer built on ultra-high-temperature piezoelectric ceramics with an ultra-low sensitivity temperature response and high impedance maintained at temperature. With 50 pC/g charge sensitivity and a ±800 g range it is the higher-range member of the family, with ±800 g, the wider bandwidth and ≤ 3% transverse sensitivity for higher-level vibration on hot machinery. Typical uses include engine and exhaust vibration, turbocharger and turbine casing testing, high-temperature industrial monitoring and thermal-cycle rigs to 288 °C.

With no built-in electronics the sensor works from −55 °C to +288 °C and pairs with any charge amplifier, which sets the low-frequency limit of the system. A 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 (≥ 10⁸ Ω) keeps long cable runs from hot zones free of ground loops. The laser-welded HEX 15.8 × 22 mm housing weighs 20.5 g, is sealed to IP68, screws down on an M5 × 3.7 (10-32 opt.) mounting hole torqued to 3.0 N·m, and takes standard high-temperature metal cables on a top-exit connector.

Rated to 288 °C

Ultra-high-temperature piezoceramics with an ultra-low sensitivity temperature response keep the C05AG4 reading accurately from −55 °C to +288 °C, with ≥ 10¹¹ Ω insulation resistance and 2,300 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 (≥ 10⁸ Ω), so the sensor bolts straight to hot conductive structures without ground loops and takes standard high-temperature metal cables. ±5% response from 1 Hz to 6 kHz (±10% over 1 – 9k Hz), resonance ≥ 30 kHz, ≤ 3% transverse sensitivity.

Compact hex, M5 mount

Laser-welded nickel-based alloy HEX 15.8 × 22 mm housing weighing 20.5 g, sealed to IP68 and rated to 2,000 g rms vibration and 3,000 g pk shock. M5 × 3.7 (10-32 opt.) mounting hole torqued to 3.0 N·m, with a top connector for a straight cable exit.
