A simple and reliable float switch designed for top mounting on virtually any process or storage vessel. T20 units utilize a single switch mechanism and float. T21 tandem units utilize two switch mechanisms and two separate floats.
Measurement Principle:
The buoyancy force of a process liquid on the float causes the float to move with the liquid surface. The movement of the float moves an attraction sleeve into the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.
