The difference between a differential pressure gauge and a pressure gauge
The difference between differential pressure gauge and pressure gauge---different uses
The difference is: Differential pressure gauges measure the pressure difference between two points, test the pressure difference between adjacent clean areas of different levels and between the clean room and the outside. The pressure gauge measures the pressure difference between this point and the atmospheric pressure of the installation site (note: the altitude of the installation site is different, so his atmospheric pressure value is also different).
2. The difference between differential pressure gauge and pressure gauge---different installation environment
Differential pressure gauges are usually installed in places that need to detect the pressure at both ends (such as pipeline valves, pipeline filter inlet and outlet)
The pressure gauge is usually installed where the pressure needs to be detected, indicating whether the pressure value is appropriate.
3. The difference between differential pressure gauge and pressure gauge---different structure principle
(1) One port of the pressure gauge should be connected to the pipe under test.
Pressure gauges are used in almost all fields of industrial process and scientific research. In the heat pipe network, oil and gas transmission, water and gas supply systems, auto repair shops and shops, the application of pressure gauges can be found everywhere. There are many types of pressure gauges. There are both general (ordinary) pointer indication types and digital types; both conventional and special types; not only contact types, but also remote transmission types...
(2) Differential pressure The two ports of the instrument should be connected to the pipeline under test respectively.
Differential pressure gauge A pressure gauge that measures the pressure difference between two different points. In addition to measuring differential pressure, it is often used in conjunction with throttling devices (such as orifice plates, venturi tubes, etc.) to measure the flow of fluids, and can also be used to measure the resistance of pipes (such as differential pressure). pressure level gauge) and tower equipment (ie two-point pressure drop), etc. There are many types of differential pressure gauges. In addition to simple U-tube differential pressure gauges, commonly used differential pressure gauges include floating ball differential pressure gauges, double bell-type differential pressure gauges, and ring-scale differential pressure gauges. wait. It can be widely used in production and scientific research departments such as electronics, medicine, biotechnology, aerospace, etc. It is an ideal instrument for pharmaceutical companies and quality supervision departments to implement GMP standards and strengthen production environment management.
