CA901 piezoelectric accelerometer

10 pC/g, −54 to 650 °C, up to 3700 Hz.

The CA901 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 CA901 is designed and built for long-term use in extreme environments characterised by high temperatures and/or hazardous areas (potentially explosive atmospheres).

  • Designed for the long-term measurement of vibration in extreme environments, such as gas turbines and nuclear applications
  • Very wide temperature range: −54 to 650 °C
  • Operational as a loose-part monitoring accelerometer
  • Available with an integral mineral-insulated (MI) cable
  • Certified for use in potentially explosive atmospheres
