The difference between differential pressure gauge and pressure gauge
1. The difference between a differential pressure gauge and a pressure gauge---different uses
The difference is: the differential pressure gauge is used to measure the pressure difference between two points, and to test the air 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 its atmospheric pressure value is different).
2. The difference between the differential pressure gauge and the pressure gauge---the installation environment is different
Differential pressure gauges are usually installed where the pressure at both ends of the gauge needs to be detected (for example: the inlet and outlet of pipeline valves and pipeline filters)
Pressure gauges are usually installed where pressure conditions need to be detected to indicate whether the pressure value is appropriate.
3. The difference between the differential pressure gauge and the pressure gauge---the structure principle is different
(1) One port of the pressure gauge should be connected to the pipe under test.
Pressure gauges are used in almost all industrial processes and scientific research fields. Pressure gauge applications can be seen everywhere in heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. There are many types of pressure gauges, not only general (ordinary) pointer indication type, but also digital type; not only conventional type, but also special type; not only contact type, but also remote type...
(2) Both ports of the differential pressure gauge must be connected to the measured pipeline.
Differential Manometer A pressure measuring instrument that measures the difference in pressure at 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 pipelines (such as differential pressure level gauges) and tower equipment ( That is, the pressure drop between two points), etc. There are many types of differential pressure gauges. In addition to simple U-shaped tube differential pressure gauges (such as Shanghai Ruihong DP-4), commonly used are float type differential pressure gauges, double bell jar 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, pharmaceuticals, biotechnology, aerospace, etc. It is an ideal instrument for pharmaceutical companies and quality supervision departments to implement GMP regulations and strengthen production environment management.
