Abstract: A dome 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) which is connected to the valve body (8) and which is 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 object of the invention is to detect state parameters of the system and to integrate continuous functionality checking and logging of the collected measurement values into the pressure regulator. In order to achieve said object, the invention proposes at least one travel sensor (15), by way of which the stroke of the valve body (8) is measurable, and a sensor-system evaluation unit (17) integrated into the housing.

Abstract: The invention relates to a measuring device, more particularly for a tubular bag packaging machine 1, to determine the concentration of at least one gas within a package 2 to be sealed, wherein it is possible to introduce a protective gas via a gas lance 3 into the package 2 to be sealed. The measuring device comprises an indicator 4, a light conductor 5, and an evaluation unit 6, wherein the indicator 4 is comprised of a fluorescent material, preferably a polymer material and arranged at the end of the light conductor 5 and within the package 2 to be sealed, wherein the evaluation unit 6 takes-up and evaluates an optical signal from the indicator 4 via the light conductor 5 to determine the concentration of the at least one gas.
