摘要 |
The invention concerns a method and a device for measurement of the nip force and/or nip pressure in a nip (N) formed by a revolving roll or a band used in the manufacture of paper. In the method and in the device, a series of measurement detectors (20l ...20n) is used, whose detectors (20) are placed across a considerable width of the paper web (W) in the transverse direction of the revolving roll (10) or the band. The measurement signals received from the different detectors (20) are passed to a switching unit (23), whose connectors (24l...24n) are controlled so that, through the switching unit (23), the signal of each measurement detector (20l...20n) is alternatingly connected to a telemeter transmitter (26) placed in connection with the revolving roll (10). By means of the telemeter transmitter (26), the series of measurement signals (Vin l...Vin n) are transmitted wirelessly to a stationary telemeter receiver (27) placed outside the revolving roll (10).
