Worldwide level and flow solutions AVAILABLE SWITCH MECHANISMS AND APPLICATION DATA Series 75 switches are available with several different switch mechanisms – each designed for specific service conditions. Brief descriptions of the individual switch mechanisms and their application are given below. For electrical ratings, see bulletin BE 42-120. Mercury switches – Series A & E Hermetically sealed switches – Series F, HS, W & X Mercury switches offer the advantage of quick visual inspection of contact conditions. Series A switches are heavy duty units with high load carrying capability. Series E switches are specifically designed to provide greater vibration resistance. Hermetically sealed switches are for use in special applications where hermetically sealed contacts are required. The Series F switch is well suited for use in applications where the process temperature does not exceed 400°C (750°F). The Series HS switch features a positively pressurized capsule for the entire swicht mechanism including contacts. It is suited for use in applications where the process temperature does not exceed 290°C (550°F). It is available with easy access terminals. These switches are ideal where salt and other corrosive atmospheres are found. Series W have silverplated and Series X have goldplated contacts; both suitable for liquid temperatures up to 230°C (450°F). Mercury High temperature mercury switches – Series 2 & 3 Available with all the features of the standard series of mercury switches. Series 2 and 3 feature nickel/copper bare wire and ceramic beaded insulation to allow use in applications where the process temperature does not exceed 400°C (750°F). Series 2 switches correspond to series E switches. Series 3 switches correspond to series A switches. High temperature mercury Dry contact switches – Series B, C, D & U These switches are specified in applications where mercury must be avoided – such as in nuclear power plant installations. Series B and C switches are general purpose units with electrical ratings dependent upon maximum liquid temperature. Series D switches are designed for high DC current applications. Series U have gold alloy contacts. Dry contact 2 Series W & X Series "HS" with terminal block Pneumatic Switches – Series J & K Pneumatic switches are employed in process industry applications where electrical power is not available or to satisfy safety requirements. The Series J bleed-type switch is intended for general purpose applications. Series K units are specially designed to provide non-bleed operation with a high degree of vibration resistance. Pneumatic AVAILABLE SWITCH ENCLOSURES Electric switches – non hazardous area = IP 65/NEMA 4X weather resistant. Electric switches – hazardous area = CENELEC/BASEEFA (IP 66)/NEMA 7/9 (IP 65) explosion proof. Pneumatic switches = NEMA 3R (IP 53) weather resistant. Consult the factory for drain/heater options. All housings are standard available with anti corrosive coating. IP 65 NEMA 4X enclosure NEMA 7/9 enclosure BASEEFA enclosure CENELEC enclosure PRINCIPLE OF OPERATION A permanent magnet ① is attached to a pivoted switch actuator ②. As the float/ displacer ③ rises following the liquid level, it raises the attraction sleeve ④ into the field of the magnet, which then snaps against the non-magnetic enclosing tube ⑤, 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. pivot ② ⑤ return spring ① ④ ③ Rising level Falling level SPECIAL PRODUCT OPTIONS Series 75 switches are available with a broad range of special options and customer engineered features to meet specific applications conditions, including the following. • Interface calibration • Customised installations dimensions • Special actuation levels • Code compliance construction • Special tank connections • Extreme temperature modifications • Class 1, Group B explosion proof electrical enclosure • Special exterior surface preparation and finish EXPEDITE SHIP PLAN (ESP) Magnetrol has implemented a quick delivery programme ‘ESP’, for the most popular units and options. The colour coded selections represent those that benefit from the shortest lead times. 3 SELECTION DATA A complete series 75 liquid level switch, consists of 1 order code: Code MODEL NUMBER – SPECIFIC GRAVITY & PRESSURE RATINGS — CARBON STEEL CHAMBERS ① Min. specific gravity Models with material construction code 1 2 A B C G J 0.60 0.75 0.60 0.55 0.50 40° C bar @ °C 230° C 42,7 69,0 34,5 51,7 27,6 29,0 58,6 25,5 38,6 20,3 0.65 0.75 0.60 0.57 0.53 Pressure rating ③ PSIG @ °F 400° C 100° F 450° F 25,2 51,7 20,7 32,7 17,2 620 1000 500 750 400 750° F 420 850 370 560 295 365 750 300 475 250 Code MODEL NUMBER – SPECIFIC GRAVITY & PRESSURE RATINGS — STAINLESS STEEL CHAMBERS ② Min. specific gravity Models with material construction code 4 A B C G P O 0.65 0.75 0.60 0.57 0.75 0.85 Pressure rating ③ 40° C bar @ °C 230° C 400° C 100° F PSIG @ °F 450° F 750° F 42,7 69,0 34,5 51,7 27,6 27,6 29,0 58,6 22,4 38,6 17,9 22,4 25,2 51,7 19,6 32,7 15,5 19,6 620 1000 500 750 400 400 420 850 325 560 260 325 365 750 285 475 225 285 ① Carbon steel chamber models are used with MATERIALS OF CONSTRUCTION Chamber Float 1 2 4 Carbon steel ① Carbon steel ① 316 SS ② material of construction codes 1 and 2 only.
