ROLL PRESSURE MEASURING APPARATUS

摘要

PURPOSE:To enable automatic control of the roll pressure finding the inter-roll pressure accurately and quickly by inserting between rolls a sheet-shaped detector section made of a piezo-electric organic high polymer material to provide a detection output thereof to an integration circuit. CONSTITUTION:A pressure detecting section 1 is equipped with electrodes 5-a and 5-b on both sides of a sheet 4 made of a piezo-electric organic high polymer. A integration circuit 2 integrates an inter-electrode signal of the detecting section 1 by time. An output section 3 outputs the output of the circuit 2 as pressure value. Then, the detecting section 1 is pinched between rolls 7-a and 7-b to be measured to measure the pressure.
