ABSTRACT:
Method and device for measuring the nip force and/or the nip pressure in a nip formed by a revolving roll or by a corresponding band employed in the manufacture of paper in which measurement detectors are arranged in a series and placed in the transverse direction of the revolving roll, preferably over the entire width of the paper web. The measurement signals of the detectors are passed to a measurement amplifier unit whose connectors are controlled so that, through the measurement amplifier unit, the signal of each measurement detector is passed to a telemeter transmitter placed in connection with the revolving roll. The telemetric messages is transmitted by the telemeter transmitter wirelessly and received by means of a telemeter receiver placed outside the revolving roll. The revolving roll is provided with a transmitter/receiver in proximity to the position of the transmitter receiver placed outside the roll. The transmitter receiver outside the roll is connected to a computer or a corresponding logic unit. Between the transmitter/receivers, a two-way wireless telemetric connection is arranged, and measurement data are transferred through the connection from the roll to the computer, and from the computer, control data for the measurement system and possible calibration data are transferred to the measurement system placed in connection with the roll.
