  • System and method for reducing thermal offset in a pressure gauge
    Patent number: 10288514
    Abstract: A pressure measurement device is provided. The pressure measurement device includes a pressure gauge having a hermetically sealed cavity. The cavity is filled with pressure transferring media that includes a first material and a compensator material. The first material has a first coefficient of thermal expansion and the compensator material has a second coefficient of thermal expansion that is lower than the first coefficient of thermal expansion. The pressure measurement device includes a pressure reading mechanism coupled to the pressure gauge and operative to convert a displacement of the pressure gauge to a pressure measurement reading.
