Beschreibung
Zusammenfassung:	A liquid-filled pressure gauge comprising a cup-shaped housing in which a metering element is located whose interior is subjected to the pressure to be measured. The front side of said housing is covered by a stiff face plate on whose inner side a transparent, resilient membrane is disposed in spaced relation which seals off the interior of said housing and which is deflected during temperature-related changes in the volume of the liquid filling. The space between the membrane and the face plate is vented externally. The transparent membrane ensures pressure compensation in the interior of the housing, while the stiff face plate protects the pressure gauge from damage to the front.
