B73 & Series 75 Sealed External Cage Liquid Level Switches DESCRIPTION Sealed external cage type level switches are completely self-contained units designed for side mounting to a tank or vessel with threaded or flanged pipe connections. These units are an industry standard in petroleum refineries and chemical plants. Thousands of these switches are in daily service throughout the world. FEATURES • Carbon steel or stainless steel welded float chamber • Service pressures up to 2240 psig (154 bar) • Process temperatures up to +1000° F (+538° C) • Specific gravity ratings as low as 0.32 • Available switch styles including dry contact, hermetically sealed and pneumatic • Single or multiple switch mechanisms available • Available switch enclosures include: APPLICATIONS NEMA 1 carbon steel for pneumatics • Accumulators • Flash tanks TYPE 4X/7/9 Class I, Div. 1 Groups C & D or Groups B, C & D polymer coated aluminum • Receivers • Knockout drums • Flare pots • Storage tanks • 1", 11⁄2", or 2" tank connections available in either NPT, socket weld, flanged side/side or flanged side/bottom construction • Scrubbers • Separators • Oil refineries • Chemical processing plants • Optional high temperature insulation available. See bulletin 41-106. • Steam and electric generating stations TECHNOLOGY A permanent magnet is attached to a pivoted switch actuator and adjustment screw . As the float rises following the liquid level, it raises the attraction sleeve into the field of the magnet, which then snaps against the non-magnetic enclosing tube , actuating the switch . The enclosing tube provides a static pressure boundary between the switch mechanism and the process. On a falling level, an inconel spring retracts the magnet, deactivating the switch. 2 5 Pivot 6 4 Return Spring 1 3 Process Liquid Process Liquid Rising Level Falling Level AGENCY APPROVALS AGENCY APPROVED MODEL AREA CLASSIFICATION FM All with an electric switch mechanism and a housing listed as TYPE 4X/7/9 Class I, Div 1, Groups C & D Class II, Div 1, Groups E, F & G All with an electric switch mechanism and a housing listed as TYPE 4X/7/9 Class I, Div 1, Group B Class I, Div 1, Groups B, C & D Class II, Div 1, Groups E, F & G All with a Series F, HS, H1, 8 or 9 electric switch mechanism and a housing listed as CSA TYPE 4X Class I, Div 2, Groups B, C & D All with an electric switch mechanism and a housing listed as TYPE 4X/7/9 Class I, Div 1, Groups C & D Class II, Div 1, Groups E, F & G All with an electric switch mechanism and a housing listed as TYPE 4X/7/9 Class I, Div 1, Group B Class I, Div 1, Groups B, C & D Class II, Div 1, Groups E, F & G All with an electric switch mechanism and an ATEX housing ATEX II 2 G EEx D IIC T6 94/9/EC IEC Ex Ex d IIc T6 IP66 Low Voltage Directives 2006/95/EC Per Harmonized Standard: EN 61010-1/1993 & Amendment No. 1 Installation Category II Pollution Degree 2 CSA ATEX / IEC Ex CE Models with two HS or two H1 switches are not ATEX approved.
