FIELD: measurement equipment.
SUBSTANCE: probe (100) for measuring the pressure of the working fluid comprises a sensor (112) of the pressure formed from single crystal material and attached to the first metal barrier (130) of the working fluid adapted for direct contact with the working fluid. The sensor (112) has a pressure electrical characteristic that varies depending on working fluid pressure. Passing element (122) is formed from a single crystal material and has a plurality of conductors extending from a first end to the second end. Passing element (122) is attached to the secondary barrier metal (116) of the working fluid and spaced apart from the sensor (112) of pressure, but it is electrically connected thereto. The sensor (112) and passing the pressure element (122) are arranged so that the secondary barrier metal (116) of the working fluid is isolated from the working fluid through the first metallic barrier (116) of the working fluid.
EFFECT: increased reliability and security.
