Diaphragm pressure gauge
2011-6-14 16:24:17

Diaphragm pressure gauges are used to measure strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, the pressure of the medium from solid floating matter, and the need to avoid the measurement medium directly entering the universal pressure instrument and to prevent the accumulation of deposits and easy cleaning.
A diaphragm gauge consisting of a diaphragm isolator and a universal pressure gauge.
Diaphragm pressure gauges and equipment are mainly connected by means of screw connections, flange connections and sanitary clamps.
Diaphragm meter is mainly used to measure the pressure of fluid medium in the production process of industrial sectors such as petrochemical, alkali making, chemical fiber, dyeing, pharmaceutical, food and alkali making.

Diaphragm pressure gauges are also produced in accordance with anti-corrosion requirements: all-plastic diaphragm pressure gauges

All-plastic diaphragm pressure gauge is a new variety developed and designed according to user needs based on the advanced technology of ordinary diaphragm pressure gauges from Japan. The main parts of the diaphragm connector are made of PVS polyvinyl chloride, the diaphragm is made of PTFE polytetrafluoroethylene, and the instrument case is made of NJ phenolic film plastic. The pressure of the acting gas or liquid.
Anti-corrosion all-plastic diaphragm pressure gauge main technical indicators:
1: accuracy level 1.5
2: Measurement range (Mpa) 0 ~ 0.1 0 ~ 0.16 0 ~ 0.25 0 ~ 0.4 0 ~ 0.6 (special specifications please specify when ordering)
3: diaphragm material PTFE polytetrafluoroethylene sheet
4: Internal working fluid (1) silicone oil
(2) Fill according to customer needs
5: Working conditions (1) Temperature Ambient temperature-20 ~ + 55 ℃
Measured medium temperature-20 ~ + 55 ℃
(2) Working pressure static load: used to 3/4 of the upper measurement limit
Alternating load: 2/3 of the upper measurement limit
Short-term pressure: used up to the measurement limit
6: Connection size (1) Thread connection: M20 * 1.5 (G3 / 8 ″ G1 / 2 ″)
(2) Flange connection A: Standard JB81-5 "Flat Welded Steel Flange" by the Ministry of Machinery Industry
B: Standard of Ministry of Chemical Industry "Acid Resistant Flat Welded Steel Flange"
C: Our company's flange standards
D: customized according to user needs
7: Knowledge instrument outer diameter (φ75mm) φ100mm
8: Model and form
Product number Connection Type Use range
YTP-75S Threaded connection For measuring the pressure of highly corrosive media. Such as: chlorine, hydrochloric acid, nitric acid, etc.
YTP-100S Threaded connection Ibid
YTP-75SF Flange connection Used for the pressure of strong corrosiveness, large viscosity and easy crystallization medium
YTP-100SF Flange connection Ibid
