Temperature-compensated pressure gauge with a switch output

A monitoring device for a temperature-compensated monitoring of a pressure of a gas or a protective gas in a high-performance switching system, the monitoring device comprising:

• a pressure-sensing element that has a coupling section that is deflectable in response to a gas pressure variation;
• a temperature-sensing element that has a variable length between a first and a second connecting section in response to a temperature variation;
• a main segment rotatable about a main axis with an articulation section attached thereto, the temperature-sensing element with its first connecting section being coupled to the coupling section of the pressure-sensing element and acts with its second connecting section together with the articulation section to influence a rotational position of the main segment about the main axis;
• and
• at least one first switching unit comprising:
• a first electrical switching element that is actuated by a rotatable cam coupled to the main segment;
• and
• a first auxiliary segment that is rotatable about the main axis and to which the first electrical switching element is attached such that a relative position between the cam and the first electrical switching element is changed by changing the rotational position of the first auxiliary segment.
