MODEL J52 REFRIGERATION LIQUID LEVEL SWITCH


The Model J52 Refrigerant Level Switches are float actuated units designed for use on liquids with 0.60 specific gravity and above.

Operating Principle


The buoyancy force of a process liquid on the float causes the float to ride on the liquid surface. The movement of the float with the liquid level moves an attraction sleeve into the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.

Applications


Ammonia
Freon
Methyl chloride
Sulphur dioxide
