🔹Thermocouple working principle They’re pretty cool because they work based on something called the Seebeck effect. Imagine you have a piece of copper wire and a piece of iron wire, and you stick them together. When you heat one end of the wires, a little bit of electricity is created! This happens because the difference in temperature between the hot end and the cold end creates a flow of electricity. This flow of electricity is called an electromotive force, or EMF for short. The cool thing a

Solenoid valves are electromechanical devices designed to control the flow through a conduit. With a wide range of applications, they are essential in circuits that regulate all types of fluids, especially water. In the following video, you will see how to work with a 220V # solenoid valve through a relay output of an #Arduino #PLCindustrial #PLC. See how it works and how easy it can be to configure your device. | Industrial Shields | Facebook
