Measurement method: Indirect measurement.
Working principle: the diaphragm pressure gauge structure principle of the diaphragm under the action of the measured medium pressure deformation, the sealing liquid is pressed, forming a pressure equivalent to P, conduction to the pressure instrument, showing the pressure value of the measured medium.
Product components: YTP anti-corrosion total-plastic diaphragm pressure gauge is a new variety developed and designed on the basis of introducing the advanced technology according to the user needs of the Japanese ordinary diaphragm pressure gauge. The diaphragm connector of the main components is made of PVS PVC, the diaphragm is made of PTFE PVC, and the instrument case is made of NJ phenolic membrane plastic, which has good anti-corrosion performance and is suitable for measuring the pressure of chlorine gas, hydrochloric acid, nitric acid and other gases or liquids with strong corrosive effect.
Isolator type: 1. Thread-thread interface type: Thread specification: M201.5 (G3 / 8 in) (G1 / 2 in) (NPT1 / 2 in); Measurement range: (Mpa) -0.1~0; -0.1~0.06; -0.1~0.15; -0.1~0.3; -0.1~0.5; -0.1~0.9 -0.1~1.5;-0.1~2.4;0~0.16;0~0.25;0~0.4;0~0.6;0~1.0;0~1.60~2.5; 0~4.0;0~6.0;0~10;0~16 ;0~25;0~40;
2. Open protruding surface flange type; Flange specifications: according to the Ministry of Chemical Industry HG, GB national standard and Japan JIS, American ANSI and other standards;
Measuring range:(Mpa)
-0.1~0;-0.1~0.06;-0.1~0.15;-0.1~0.3;-0.1~0.5;-0.1~0.9
-0.1~1.5;-0.1~2.4;0~0.16;0~0.25;0~0.4;0~0.6;0~1.0;0~1.60~2.5;
0~4.0;0~6.0;0~10
7. Temperature influence: because the thermal expansion of the sealing fluid and the diaphragm stiffness are related to the temperature, when the use temperature deviation from 20℃± 5℃, there is an error in the temperature influence, and its value is 0.1% / ℃.8. liquid level difference: if the diaphragm pressure gauge connected by the hose is installed at different positions from the pressure part and the pressure instrument, the liquid level difference will form the influence of a pressure difference P, P= specific difference of sealing fluid.
Product applications:PVC Diaphragm Seal for gauge YM series diaphragm pressure gauge is suitable for measuring corrosive, high viscosity, easy crystallization, easy solidification, high temperature of liquid, gas or granular solid medium pressure and must avoid the measurement medium directly into the pressure instrument and prevent sediment accumulation and easy to clean occasions. Diaphragm pressure gauge is mainly used in petroleum, chemical, chemical fiber, dyeing and chemical, pharmaceutical, alkali food and other industrial sectors.
