I wish I knew what a level switch is!
In a level application, you can control your process in different ways. A continuous application has a transmitter sending online information to the control system. In a simple process, you might use an level switch to take action if you have 50 or 100 percent of the level.
A level switch signals the system if you have the correct level or not. If not, then the system will open a valve, start a pump, or whatever to return the product to the proper level.
You can also add a level switch as a layer of protection. If the transmitter fails and the product goes beyond its proper level, then the level switch will alert the system.
You can have more advanced applications using level switches, but we’ll save that topic for another #WishIknew.
