NIP WIDTH SENSING SYSTEM AND METHOD |
摘要 |
Devices for measuring a nip width between rolls of a press nip include one or more sensors adapted to be placed in the nip while the nip is stationary. The elec-trical resistance of each sen-sor corresponds to the size of the nip width, whereby a nip width or a nip width distribution may be deter-mined by measuring the sensor resistance(s). Methods of measuring a nip width distribution include provid-ing a plurality of force sen-sitive resistor sensors each of which respond to pressure applied thereto to provide a variable sensor resistance as a function of the amount of pressure and the area of the pressure exerted on the sensor.
