Cảm biến đo độ rung CE311 piezoelectric accelerometer VIBRO METER AG P/N#444-311-000-021
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).
