DEVICE AND METHOD FOR CHECKING AND MONITORING THE PRESSURE IN PRESSURE PIPES AND/OR CONDUITS

摘要

A device with a chamber (110), which has a chamber opening (120) and a plunger (130) which can move in the chamber (110) to change a chamber volume which is defined by the plunger (130) and by one chamber wall (140) and which adjoins the chamber opening (120). Said device has a device (150) for measuring the pressure in the chamber (110) or for measuring a force F, wherein F is the force which is exerted on the plunger (130) to change the chamber volume.
