Pressure vacuum gauges are widely used in gas transportation, measuring the pressure of various liquids, gases, steam and other media that are non-corrosive, non-explosive, non-crystalline, and non-solidified in pipeline liquids and airtight containers.
Vacuum gauge: Based on atmospheric pressure, it is used to measure instruments that are less than atmospheric pressure.
The vacuum gauge is used to measure the pressure or negative pressure of the non-crystallized, non-solidified liquid, gas or vapor medium that has no corrosive effect on steel, copper and copper alloys, and has no explosion hazard.
The shockproof vacuum gauge is used to measure the negative pressure of a non-corrosive, non-crystalline medium under vibration and pressure fluctuations.
Electric contact pressure vacuum gauges and electric contact vacuum gauges. Copper and copper alloys are non-corrosive and non-explosive, non-crystalline and non-solidified liquids, gases and other media (pressure) and negative pressure. When the pressure reaches a predetermined value, with the help of the contact device, the control circuit can be connected or disconnected, and an electrical signal can be sent out at the same time.
Electric contact pressure vacuum gauge is used to measure the pressure and negative pressure of non-corrosive, non-explosive, non-crystalline, non-solidified liquids, gases and other media of copper and copper alloys. When the pressure and negative pressure reach a predetermined value, the magnetic electric contact device can be used to connect or disconnect the control circuit
The electric contact vacuum gauge is used to measure the negative pressure of liquid, gas or steam without corrosion of copper and copper alloys. And when the negative pressure reaches a predetermined value, an electrical signal is sent to turn on or off the control circuit.
Stainless steel vacuum gauge and stainless steel pressure vacuum gauge are used to measure the pressure and negative pressure of liquid and gas medium that have no corrosive effect on stainless steel 316, 316L and 0Crl8Ni12MO2Ti. All stainless steel has stronger corrosion resistance to the environment.
The acid-resistant pressure vacuum gauge is used to measure the pressure and negative pressure of nitric acid and alkali liquid media; the acid-resistant vacuum gauge is used to measure the negative pressure of nitric acid and alkali liquid media.
The main features of vacuum pressure gauges are as follows:
(1) Stable performance, high measurement accuracy and fast response speed
(2) It is an absolute vacuum gauge, with an accuracy of 0.5 or higher, which can be used as a standard vacuum.
(3) What is measured is the total pressure, including the pressure of gas and steam
(4) The result of the measurement has nothing to do with the type, composition and nature of the gas
(5) In the process of measuring m, the vacuum gauge itself sucks and deflates very little, which will not affect the measured atmosphere
(6) There are no high temperature parts inside the vacuum gauge, which will not decompose the oil vapor
(7) If made of corrosion-resistant materials, the pressure of corrosive gas can be measured
(8) The structure is firm, and it is easy to seal and install
(9) The operation is simple, no adjustment is required, but regular calibration is required
