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 A P P L I C A T I O N S • Accumulators • Receivers O P T I O N S • Flare pots • ATEX housing • Scrubbers • Flanged connections • Flash tanks • Temperature extensions • Knock-out drums • Low specific gravity calibration • Storage tanks • ASME B31.1 Construction • Separators • Additional QC testing 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 ➀ into or out of the field of a switch actuating magnet ➁ causing switch operation. A nonmagnetic barrier tube ➂ effectively isolates the switch mechanism from the controlled liquid.

Design calculations, design prints and weld qualifications are available for audit. All chamber branch and circumferential weld joints are designed to achieve FULL penetration. WELDING All welding is performed by qualified welders and per procedures required by the ASME Boiler Pressure Vessel Code Sec. IX. Welds are visually inspected for FULL penetration. All other non-destructive examination is performed per ANSI B31.1. MATERIALS OF CONSTRUCTION All pressure-retaining materials are procured with Certificates of Conformance to assure compliance of components with required standards. HYDROSTATIC TEST All chambers are hydrostatically tested at 1.5 times the design pressure.
