Pressure gauge assembly THCR-II a for kryo use



Model THCR-II A is a combined differential pressure gauge, used for indication of differential pressure in cryogenic containers that contain liquefied gases. THCR-II A contains three basic elements - differential pressure gauge, static pressure gauge and multifunction valve. All set is placed in an aluminum heavy-duty case for increased protection of the entire device.

MULTIFUNCTION VALVE: Replaces 4 original valves on the container. Broken differential or static pressure gauge may be replaced without isolation gas pipeline, only by gradual adjusting. When using multifunction valve, the whole process is simplified, random step may be eliminated and thus the differential pressure gauge is protected and its life-time is prolonged. Also the area of pipeline installation my be reduced compared to the original 4-valve design.
