Side Mounting Liquid Level Switches DESCRIPTION Magnetrol side mounting controls mount horizontally to any tank or vessel through a threaded or flanged pipe connection. Standard models are normally equipped with a single switch mechanism for high or low level alarm or control applications. Tandem models, with two switch mechanisms, are available for two-stage applications. FEATURES • Body material of cast iron, carbon steel or stainless steel • 300 series stainless steel float and trim • Threaded or flanged mounting • Specific gravity ratings down to 0.50 • Process temperatures to +1000° F (+538° C) • Choice of float size: • 21⁄2" (64 mm) • 21⁄2" × 4" (64 × 102 mm) • • • 3" (76 mm) 31⁄2" (89 mm) 3" × 5" (76 × 127 mm) • Field-adjustable level differential • Choice of switch mechanism: Dry contact Hermetically sealed Pneumatic • Choice of switch mechanism enclosure: NEMA 1 carbon steel for pneumatic TYPE 4X/7/9, Class I, Div. 1, Group C & D, polymer coated aluminum TYPE 4X/7/9, Class I, Div. 1, Group B, polymer coated aluminum APPLICATIONS • Fuel tanks • Day tanks • Flash tanks • Scrubbers • Cooling towers • Dump valve controls • Condensate receivers • Boilers • Deaerators • Holding tanks TECHNOLOGY Snap switch Side mounting units employ permanent magnetic force as the only link between the float and the switching element. As the pivoted float follows liquid level changes, it moves a magnetic sleeve into or out of the field of a switch actuating magnet causing switch operation. A nonmagnetic barrier tube effectively isolates the switch mechanism from the controlled liquid.
