CA306 piezoelectric accelerometer

50 pC/g, −55 to 500 °C, up to 3000 Hz.

The CA306 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 CA306 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 aero-derivative and industrial gas turbines
  • High sensitivity: 50 pC/g
  • Wide temperature range: −55 to 500 °C
  • Available as a sensor only (no integral cable) or with an integral mineral insulated (MI) cable with a flexible stainless steel overbraid
  • Certified for use in potentially explosive atmospheres
