CA280 piezoelectric accelerometer

100 pC/g, −55 to 260 °C, up to 10000 Hz.

The CA280 piezoelectric accelerometer is a high-quality, high-reliability vibration sensor with a piezoelectric sensing element that provides a charge output. Accordingly, an external charge amplifier (IPC704 signal conditioner), is required to convert this charge-based signal into a current or a voltage signal.

The CA280 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).

Features
  • Designed for the long-term measurement of vibration in extreme environments, such as gas turbines, gearboxes and compressors
  • Very high sensitivity: 100 pC/g
  • Very wide frequency response: 0.5 to 10000 Hz
  • Available as a sensor only (no integral cable) or with an integral soft-line cable with a flexible stainless steel hose
  • Certified for use in potentially explosive atmospheres
