How to choose a pressure gauge?
The first is selected according to the type of environmental characteristics, such as whether the need of explosion-proof, and then select the range, the general scale selection principle is that the pointer under normal pressure, shown in the 2/3 position is appropriate, margin; according to the actual demand, choose the suitable range of precision; the interface is needless to say. Good luck！
Maximum pressure (range of measurement)?Dial diameter?Connection mode?Medium condition? (corrosion, viscosity, heat, etc)Work environment? (vibration, pulsation, high temperature, high pressure, overpressure, etc.)Other special requirements (material, protection, heat dissipation, damping, etc.)
A digital or a pointer is a manometerWorking environment, vibration proof, stainless steel...Accuracy classMeasuring range, how many MPA?Dial diameter
