  • Page 23: Calibration

    General description Figure 2.3a shows the calibration principle. Calibration curves for several applicable pulp types are saved in SMART-PULP’s memory for each sensor type. The calibration curves, experimentally defined in Valmet Automation’s laboratory, represent consistency (% Cs) as a function of the shear force (N) acting on the sensor.

The pulp type to be calibrated must be transmitters, including the P1 and P2 values active, i.e. in measurement, when you do the calculated by SMART-PULP after execution of the calibration.
