Lip Gap Measuring in Paper Manufacture
In paper manufacture the lip gap at the headbox Technical data
determines the thickness of the paper. Paper - measuring ranges: 0 - 15 (40 mm)
machines usually have a lip width between 4 and 6 - accuracy: 50 µm
metres. The measuring task is a constantly - excellent long term and temperature stability
monitoring the gap between the upper and lower lip
as a quality relevant variable. Ambient conditions
To manage this application a non-contact eddy - harsh industrial environment with water
current displacement sensor is fitted either to one or and other aggressive liquids
better to both sides. A steel or aluminium target
plate fitted opposite the sensor serves as a Configuration
measuring target. DT315-SM-I single channel electronics with power
