WYE-X Series is a premium capsule pressure gauge designed for low pressure measurement on various condition. This series are light pressure gauges with cauterization resisting referring to the structure of normal gauges with capsule, used in the equipment of boiler pipe and gas tube to measure the low pressure or loading pressure of each kind of liquid medium which have higher request of cauterization-resisting.

The gauge is made up of measurement system (including flange connection head, ripple diaphragm), turnable parts (including connection rod), display parts (needle, dial), and crust (including crust and washer, and glass). The working principle is when the ripple capsule element under the pressure from measured medium, the free end will raise transfiguration accordingly, referring to the connection rod to make the turnable part circle and blow up, then the needle will display the data. There is protection device to prevent the capsule from transfiguration when over loading, and there is zero adjustment device also, which can adjust zero point conveniently.
