Pressure sensor how to control the frequency converter, the specific circuit, thank you
This I also want to know the specific, in fact, we have a unit before the project has variable frequency constant pressure pump, there are ready-made circuits, that is, they are too lazy to learn...
This is very simple, that is your pressure sensor remote pressure gauge, in fact is a sliding rheostat, it can with the voltage input signal pressure adjustment of the inverter output frequency converter to adjust.
The pressure sensor is one of the most commonly used sensor in industrial practice, which is widely used in various industrial control environment, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil, electric power, shipbuilding, machine tools, plumbing and other industries, following a brief introduction of some commonly used sensor principle and its application
