Question:

Can you tell me how to control the circuit with the pressure sensor PLC?

I would like to ask how to use the pressure sensor PLC together to control the circuit, can not even connect directly, is not yet what the components?. That's how the pressure is set, and of course I don't have a man-machine interface. Tell me if you can buy a temperature monitor like a temperature sensor. Specific how to do, please answer, the reward is very low, please forgive me. It's urgent. It's urgent

Answer:

You can use the pressure transmitter + digital display of intelligent control instrument, you can display the actual pressure value, and in accordance with the set pressure to control other appliances, easy to use, relatively low cost
Output 4-20mA signal pressure transmitter, PLC analog input point, through the PLC program programming, you can achieve the desired control function.
The 2 floor is about the same. Sensor output is mostly mV level signals, while PLC and other instruments are aimed at industrial signals, 4 to 20mA, 0 to 5V, and 0 to 10V. From the Ma level to industrial signals there is a signal amplification and conversion problems, which is related to the design of sensor circuits, is generally not allow others to zoom in and out. The transmitter is a sensor for amplifying and outputting industrial signals. Or is it convenient to buy the pressure transmitter directly, and the price of the common pressure transmitter is not high enough to try.
