B40 Liquid Level Switch D E S C R I P T I O N The Magnetrol B40 liquid level switch is specifically designed and constructed for high pressure, high temperature service conditions. F E A T U R E S • Choices of chamber materials include carbon steel, stainless steel and chrome-moly • 300 series stainless steel float. • Choice of switch mechanism: Dry contact Hermetically sealed • Minimum specific gravity 0.65 • Choice of switch mechanism enclosure: TYPE 4X polymer coated steel TYPE 4X/7/9 Class I, Div. 1, Groups C & D, polymer coated aluminum or cast iron TYPE 4X/7/9 Class I, Div. 1, Group B, polymer coated aluminum or cast iron • Choice of tank connection: 1" welding nipples 1" or 11⁄2" socket welds O P T I O N S A P P L I C A T I O N S • Accumulators • Receivers • Flare pots • ATEX housing • Scrubbers • Flanged connections • Flash tanks • Temperature extensions • Knock-out drums • Low specific gravity • Storage tanks • Separators T E C H N O L O G Y B40 level switches 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.
