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).
FeaturesDesigned for the long-term measurement of vibration in severe environments, such as heavy-duty gas turbines and steam turbinesHigh frequency response: up to 8000 HzHigh sensitivity: 50 µA/gCurrent output (50 µA/g) for signal transmission over long distances: up to 1000 mCertified for use in potentially explosive atmospheres
