Process data
Measuring task:
Pressure measurement
Measuring point:
Pressure screen
Measuring range up to:
2 bar
Medium:
Paper suspension
Process temperature:
+20 … +50 °C
Process pressure:
+1.5 … +2 bar
Special challenges:
Pressure surges, abrasion, contaminants in the suspension
Application
Pressure screens are used to filter out impurities and separate fibres in stock preparation. A rotating screen basket inside the filter does the actual filtering. Pressure screens have an inlet for the suspension, an outlet for accepted stock and a discharge for rejected stock and contaminants. The process conditions are characterized by pressure surges as well as abrasion and contaminants in the stock. Efficient screening requires a controlled pressure difference between inlet and outlet, which therefore requires continuous, reliable measurement.
