Abstract (en)
[origin: WO2017191171A1] The invention relates to a dome-loaded pressure regulator for regulating gas pressure, having a housing (1), a fixed valve seat (10), a movable valve body (8), a closing spring (9) acting on the valve body (8), and a diaphragm (4) connected to the valve body (8), said diaphragm (4) being able to be subjected to a control pressure, settable via a gas pressure spring, in the opening direction and to a secondary pressure in the closing direction. The problem addressed by the invention is that of sensing state parameters of the system and of integrating continuous functional testing and recording of the measured parameters into the pressure regulator. To solve this problem, the invention proposes at least one position sensor (15), by way of which the travel of the valve body (8) is able to be measured, and a sensor-system evaluation unit (17) integrated into the housing.
