Pramp Automation and Calibration
Category: Level
Product: Level Switches
Sub Product: Side Mounted Magnetic Level Switch
The Float assembly carries with it a permanent magnet, which is opposed by a similar magnet in the switch assembly. The adjacent poles of the two magnets are arranged so that they repel each other. It is this principle, which is employed to change over the contacts with a snap action.
