The differential pressure-pressure gauge is suitable for liquid and gaseous media as long as these are not highly viscous or crystallised.
Two independent pipe spring measuring systems work in the stable round housing. Both system indicators rotate around the same centre axis and display the pressures separately. The pointer with the lower pressure is designed as scale window. On this scale, the differential pressure of the respective display range can be read directly. Both single pressures are also directly visible.
Housing: Black steel, measuring system and indicator: Cu alloy, window: instrument plate glass
