Description 50 µA/g, −40 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). Features 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
