New module for faster calibration of online consistency sensors

February 21, 2017  By P&PC Staff

Feb. 21, 2017 – Based on a customer request, PulpEye has launched a new module, ConsistencyEye, for faster measurements and calibration of sensors for different process streams.

This method is particularly suitable for measurement of low consistency streams, such as those found in paper and board machines’ stock preparation departments.

The company explains that there is currently no quick way to measure consistency of different fibre streams for calibration of consistency sensors. Usually the measurements are done manually, which takes time and the result may be influenced by how the measurement is done.


“The module is of interest to any mill with many consistency sensors to be calibrated regularly,” says Öjvind Sundvall, managing director of PulpEye, “As the consistency influences, among other things, the amount of chemicals added and the refining, it is very important that the consistency sensors always give the actual values. In stock preparation departments there are many flows where false or slow consistency measurements during calibrations may result in substantial costs caused by wrong product quality.”

Sundvall continues: “Our first ConsistencyEye costumers confirm that a calibration of the consistency in a flow takes only two to five minutes instead of earlier typically 40 to 60 minutes for the existing laboratory method. In addition to that, the measurement result is independent of who does the calibration, which contributes to quality secured product properties.”
