Tuffy® II – Float Level Control with Electric Switch
A compact level switch designed for horizontal mounting in a tank or vessel through threaded or flanged pipe connections. Fixed or adjustable wide, as well as narrow, differentials provide application flexibility.
Measurement Principle :
Buoyancy force of process liquid on a float causes the float to move with the liquid’s surface. Float movement pivots a magnet into the field of a like-charged switch magnet. As the magnets repel each other, the switch magnet moves, actuating the switch.
