摘要

Device and process for measuring a width of the narrow passage between two rolls of a narrow passage between press rolls.Devices for measuring a width of the narrow passage between rolls of a narrow passage between press rolls include one or more sensors adapted to be placed in the narrow passage.Re rolls while it is stationary.The electric resistance of each sensor corresponds to the size of the width of the narrow passage between rolls.By means of a width of the narrow passage between rolls or a distribution width of narrow passage between rolls can be determined by measuring the (s) resistance (s) of the sensor.The processes of measuring a distribution of width of the narrow passage between rolls include providing a plurality of sensors of a resistor sensitive to strength.Each of which responds to pressure applied to the same to provide a variable resistance sensor as a function of the amount of pressure and the area of the pressure exerted on the sensor.
