<p>The device has a recorder (5) for recording deviation of pressure prevailing in a flexible fluid filled hose (1), which is hermetically closed at two ends (2, 3), where pressure acts from an outer side into a point between the ends of the hose. The recorder comprises a strain gauge (6) or extension meter, where deformation of the gauge is converted into an electrical signal, where deformation is caused by elongation and/or deflection due to increase of the pressure in the hose relative to the pressure prevailing in the hose. Intensity of the gauge represents a measure at a point in the hose.</p> |
