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: NEMA 1 carbon steel for pneumatics TYPE 4X/7/9 Class I, Div. 1 Groups C & D or Groups B, C & D polymer coated aluminum • 1", 11⁄2", or 2" tank connections available in either NPT, socket weld, flanged side/side or flanged side/bottom construction • Optional high temperature insulation available. See bulletin 41-106.
APPLICATIONS
• Accumulators • Receivers • Flare pots • Scrubbers • Oil refineries • Flash tanks • Knockout drums • Storage tanks • Separators • Chemical processing plants
• 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.

Models with two HS or two H1 switches are not ATEX approved. IEC Installation Instructions: The cable entry and closing devices shall be Ex d certified suitable for the conditions of use and correctly installed.
For ambient temperatures above +55° C or for process temperatures above +150° C, suitable heat resistant cables shall be used. Heat extensions (between process connection and housing) shall never be insulated. Special conditions for safe use: When the equipment is installed in process temperatures higher than +85° C the temperature classification must be reduced according to the following table as per IEC60079-0. Maximum Process Temperature < 85° C < 100° C < 135° C < 200° C < 300° C < 450° C Temperature Classification T6 T5 T4 T3 T2 T1
