YPF diaphragm pressure gauge from Shangyi Fourth Factory

The YPF diaphragm pressure gauge from Shangyi Fourth Factory is suitable for measuring the pressure of liquids, gases, or vapors that are non explosive, non crystalline, non solidifying, have high viscosity, but have no corrosive effect on copper and copper alloys.
Diaphragm pressure gauges are suitable for measuring the pressure or negative pressure of various fluid media that are corrosive, non solidifying, or non crystalline. The corrosion resistance performance depends on the membrane material

structural principle
The instrument consists of a measurement series (including flange joints, corrugated diaphragms), a transmission indicator mechanism (including connecting rods, gear transmission mechanisms, pointers, and dials), and a housing (including a case and cover ring). The instrument casing is a splash proof structure with good sealing performance, which can protect the internal mechanism from contamination.
The working principle of the instrument is based on the deformation of the elastic element (diaphragm on the measurement system). Under the pressure of the measured medium, the diaphragm is forced to undergo corresponding elastic deformation displacement. With the help of the connecting rod group and the transmission mechanism, the measured value is amplified and indicated on the dial by a pointer fixed on the gear
