PRINCIPLE OF OPERATION : 

Telelin Level Switch works on Magnetic Principle. The float carries a permanent magnet which is opposed by a similar magnet inside the switch. As the float moves up, The inside magnet which carries contacts repels and moves away from the float magnet. This ensures a snap action and change over of contacts. This Action is completely gland less and hence no leakage possibility into the switch housing. These switch can be successfully used in water tanks, steriliser, tea boilers, high pressure boilers, chemical tanks, water heaters, storage tanks and innumerable other applications.

“Telelin” make Bi-Colour type level indicators are designed, using simple magnetic principle. Level is indicated by changed colour of Bi-colour magnetic rollers. They are mounted on aluminium channel, protected by sturdy aluminium box which is moved by magnetic float in the main line pipe chamber. The roller turns upside down changing colour from yellow to red. Thus Showing level . It is used at places where there is flammable toxic or high temperature and high pressure fluid where glass type level indicators cannot be used .
