ITY & QUAL LESS D E T R ASSU ICE COS V R E S 01 ® ISO 90 Magnetrol Model J52 refrigerant level switches are float actuated units designed for use on liquids with 0.60 specific gravity and above. They utilize the Magnetrol magnetic principle to assure dependable performance. Series J52 Refrigerant Level Switches Model J52 Refrigerant Level Switch FEATURES * Temperatures from: -45°C to +40°C (-50°F to +100°F). * Maximum working pressure to 20.5 bar (300 PSIG). * Housing is completely sealed against entrance of moisture, preventing internal frost formation. * Conduit seal with 610 mm (24") lead wires prevents entrance of moisture laden air into the switch housing. * Float chamber is a welded assembly fabricated from two low carbon steel sections. * High and low level switch actuation is easily field adjustable between 13 mm (0.50") and 38 mm (1.50"), factory set for 38 mm (1.50"). * Vibration resistant switch mechanism has been specifically developed to provide reliable and troublefree operation. * Housing cover seal of Viton A o-ring is used between housing cover and base to provide an air tight seal. * Housing base can be rotated 360°. * Dry contact switch mechanisms available for -30°C (-20°F) or for excessive vibration conditions. * Baffle plate provided with the switch mechanism to prevent electrical wiring interference. * Choice of enclosure: NEMA 4x, black steel cover NEMA 4, transparant Lexan® cover NEMA 4x/7/9, explosion proof. * Used with most commercial refrigerants including Ammonia, Freon, Methyl, Chloride and Sulphur Dioxide.

As the float ➂ rises following the liquid level, it raises the attraction sleeve ➃ into the field of the magnet, which in turn snaps against the non-magnetic enclosing tube ➄ actuating the switch. The enclosing tube provides the static pressure boundary between the switch mechanism and the process.
