Product Description

Application
Diaphragm pressure gauge is widely used in the process of petroleum, chemical, alkali production, chemical fiber, pharmacy, food, textile industries; suitable for measuring the corrosive, high temperature, high viscosity, easy to crystallization, easy to solidification and solid floating medium pressure, and for some measurement medium which cannot be used directly into the universal pressure gauge and the place where the clean to prevent precipitation pressure detection, diaphragm separator and universal pressure gauge must be used to form a system of diaphragm table.

 

Theory
When measuring the pressure of medium P acts on the diaphragm, diaphragm deformation, compression pressure gauge sealing fluid pressure system, make its forming P - delta P stress, when the diaphragm of the rigid enough hours, the delta P are also small, pressure meter pressure system formed nearby for measuring the pressure of medium.

 

Working theory

Diaphragm pressure gaug's temperature
Diaphragm pressure gaug's temperature is ralted with sealing liquid membrane expansion coefficient stiffness and pressure parts temperature. In the use of temperature deviation 20±5ºC, changing rate of maximum value affected by the temperature is not greater than 0.1%ºC, flexible takes (far) is not greater than 0.1 + 0.025% (L - transmitting pressure conduit length m), appropriate sealing work fluid is chosen according to the use of different environment.

 

Sealing liquid
Sealing liquid choice for reliability and safety, suitable liquid is chosen according to purposes.

Sealing Liquid	Temperature Range	Specific Weight g/cm3	volume coefficient1/ºC	Use
Heavy viscous	-10~200ºC	1.07	0.95×10-3	high temperature
low viscous silicone	-30~100ºC	0.94	1.08×10-3	general use
glycerin solution	-5~100ºC	1.27	0.61×10-3	food use

Corrosion resistance
corrosion resistance is ensured through proper selection and measurement of the medium contact part of the diaphragm, the flange and the sealing gasket materials.Material: OCR17NI12MO2(SUS316L), onel alloy, hartz alloy, ta,f4Flange material: sus304, sus316, Lined with four fluorine.
