External Cage Displacer Actuated Liquid Level Switches DESCRIPTION High Pressure Liquid Level Switches are displacer actuated units, utilizing a single switch mechanism for level alarm or control functions. These units are designed for service pressures up to 5000 psig (345 bar) and liquids with specific gravities of 0.40 and above. They utilize the Magnetrol magnetic principle to assure dependable performance. FEATURES • Fabricated carbon steel cages are standard for all models. • B74 available with 304 & 316 SS cages • Sealed or flanged cages available • Inconel displacer spring and stainless steel trim • Stainless steel displacers • Pressures to 5000 psig (345 bar) • Temperatures to +750° F (+399° C) • Specific gravity down to 0.40 • Choice of switch mechanism: Dry contact Pneumatic Hermetically sealed • Choice of switch enclosure: NEMA 1 carbon steel for pneumatics TYPE 4X/7/9 Class I, Div. 1, Groups C & D polymer coated aluminum TYPE 4X/7/9 Class I, Div. 1, Group B polymer coated aluminum Model C74 Flanged External Cage with TYPE 4X/7/9 Switch Housing APPLICATIONS • Hydraulic accumulators • Choice of tank connections: NPT Socketweld Side/side flanges Side/bottom flanges • Optional custom high temperature insulation available. See bulletin 41-106 for details. • Natural gas receivers • H.P. scrubbers • Hydrocarbon flash tanks OPTIONS • Special levels/body extensions • Gold switch contacts • 316/304 SS chambers • Interface (except B74) • NACE • Vent and drain connections TECHNOLOGY The weight of the displacer is supported by the spring . Rising liquid level imparts buoyancy forces on the displacer allowing the spring to compress. The attraction sleeve , attached to the spring, moves upward into the field of a permanent magnet . Magnet motion causes the switch to actuate. A non-magnetic barrier tube provides a static pressure boundary between the switch mechanism and the displacer assembly. 5 5 4 3 6 3 4 6 2 1 1 SPECIFICATIONS SWITCH MECHANISMS AND ENCLOSURES SERIES J & K PNEUMATIC SWITCHES SERIES F, HS, H1 & 8 HERMETICALLY SEALED SWITCHES • Suited for applications where electrical power is not available • Ideal for use in salt and other corrosive atmospheres • Bleed and non-bleed designs • Series “HS” and “H1” are positively pressurized capsules for entire mechanism and contacts • Process temperatures to +400° F (+204° C) • Process temperatures to +750° F (+399° C) SWITCH ENCLOSURES SERIES B, C & D DRY CONTACT SWITCHES • Designed for AC and DC current applications • TYPE 4X/7/9 aluminum enclosures • Designed to meet Class I, Div. 1, Groups C & D and Class I, Div. 1 Group B • Series C for process temperatures to +450° F (+232° C) • Optional housing heaters and drains available for some enclosures • Pneumatic switch mechanisms available with a NEMA 1 enclosure BASIC ELECTRICAL RATINGS Voltage 120 VAC 240 VAC 24 VDC 120 VDC 240 VDC 2 B 15.00 15.00 6.00 0.50 0.25 Switch Series and Non-Inductive Ampere Rating C D F HS H1 15.00 15.00 10.00 1.00 0.50 10.00 — 10.00 10.00 3.00 0.25 — 4.00 0.30 — 5.00 5.00 5.00 0.50 0.25 1.00 1.00 1.00 0.40 — 8 1.00 — 3.00 — — 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, H1, HS or 8 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 IP 66 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 IEC Installation Instructions: The cable entry and closing devices shall be Ex d certified suitable for the conditions of use and correctly installed.
