Sensor selection - Pulp and Paper industry

Following are the top features required of a quality vibration sensor in the Pulp and Paper industry, along with the reasons why:
  • Low frequency response ≤ 1,0 Hz: For low rotational speed of rolls
  • Elevated temperature 120 to 150 °C (250 to 300 °F): For dryer section heat and humidity
  • IP 68 cable/connector assembly: For wet environment and frequent roll changes
  • Good signal-to-noise ratio: For bearing defect detection 

Good - General purpose monitoring:

- Installation robustness:

Best - Elevated temperatures:
