Abstract (en)
[origin: EP1932791A1] The method involves using at least one sensor with at least one Wheatstone bridge with at least one force transducer (7) influenced by the tension in the web. It involves amplifying the bridge diagonal voltage in an amplifier that produces a tension signal and is periodically loaded with at least one resistance via an intermittently operated switch while the moving web is loaded by the tension. The operability of the sensor(s) is determined from the controlled influence of the tension signal by the load and output as an error signal.
