Product Description:

‌

‌ vacuum pressure gauge ‌ is a kind of instrument for measuring less than atmospheric pressure based on atmospheric pressure. It is mainly used to measure the vacuum pressure of liquids and gases that are non-explosive, non-crystalline, non-solidifying, and non-corrosive to copper and copper alloys. Vacuum pressure gauge is widely used in various industrial automatic control environment, involving oil pipelines, water conservancy and hydropower, railway traffic, intelligent buildings, production automatic control, aerospace, military, petrochemical, oil Wells, electric power, ships, machine tools, pipeline air supply, vacuum equipment and many other industries ‌

Working principle
The working principle of the vacuum pressure gauge is to determine the pressure by measuring the bending amount of the spring or diaphragm. When the pressure of the measured gas is applied to the spring or diaphragm, it will cause a small deformation, which is proportional to the applied pressure. The displacement of the spring or diaphragm is connected to a measuring pointer which displays the pressure on the dial ‌

Type and range
According to its range, the vacuum pressure gauge can be divided into the following types:

‌ micro-pressure vacuum gauge ‌ : low range, usually below 100mbar.
‌ low pressure vacuum gauge ‌ : the measuring range is 100mbar~1bar.
‌ medium vacuum gauge ‌ : the measuring range is between 1bar~10^-3mbar.
‌ high vacuum gauge ‌ : measuring range of 10^-3mbar to 10^-9mbar ‌
Application field
Vacuum pressure gauges are widely used in many fields:

‌ Air conditioning refrigeration ‌ : used to detect the pressure and leakage of the refrigeration system.
‌ vacuum drying ‌ : used to monitor the change of gas pressure in the drying process and control the drying speed.
‌ semiconductor manufacturing ‌ : used to monitor the change of gas pressure in vacuum system to ensure manufacturing quality.
‌ aerospace ‌ When conducting experiments in a vacuum environment, accurate measurement of the size of the vacuum is very important ‌.
Care and maintenance
When using vacuum pressure gauges, the following points need to be noted:

‌ calibration ‌ : Calibration should be performed before use, usually by connecting the pressure gauge to the vacuum system to be measured and comparing it with a multifunctional vacuum gauge.
‌ Check ‌ : Before use, check whether the meter head, air inlet and outlet and connecting rod and other components are in good condition.
‌ Avoid inversion or impact ‌ : so as not to affect the reading accuracy and sensitivity of the meter head.
‌ real-time monitoring ‌ : real-time monitoring during use.
‌ cleaning and maintenance ‌ : should be cleaned and maintained in time after use to extend its service life ‌
