CE311 piezoelectric accelerometer

50 µA/g, −55 to 125 °C, up to 8000 Hz.

The CE311 piezoelectric accelerometer is a high-quality, high-reliability vibration sensor with a piezoelectric sensing element and integrated electronics that provides a current output.

The CE311 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 severe environments, such as heavy-duty gas turbines and steam turbines
  • High frequency response: up to 8000 Hz
  • High sensitivity: 50 µA/g
  • Current output (50 µA/g) for signal transmission over long distances: up to 1000 m
  • Certified for use in potentially explosive atmospheres
