DATASHEET level switch Type lsg FUnCTion The level switch type LSG is designed for versatile applications in shipbuilding and plant engineering. The TeCHniCAl DATA materials housing gun metal RG5 or RG10 grated flange (produced to customer specification) flange gun metal RG5 or stainless steel seams and all welded stainless steel float. float unit flat seal 1.4571 rubber seal EPDM, NBR70 construction comprises a rugged housing with inte- connection in one piece without any seals or welding The principle of operation is, one permanent magnet forms part of a float assembly which rises and falls with protection type positioned within the switch so that the adjacent poles min. density oil and sea water proofed Novapress IP68 cable gland changing liquid level. A second permanent magnet is max. pressure of the two magnets repel each other. max. temperature ambient temperature A change of liquid level which moves the float through its permissible travel will cause the float magnet to move and repel the switch magnet to give the snap action switch operation. 42 bar (floater) 0,46 g/cm³ -40°C…+125°C mounting position top or side contact mode SPDT electrical connection weight cable gland, M20x1,5, IP68 ca. 4,5 kg The float, test button and screw plug are manufactured 1.4571 stainless steel and consequently corrosion- resistant, durable with good shock and vibration capability. The test button provides a high compressi- ve strength providing positive actuation during opera- tion. Depending on the wiring of the micro switch it is possible to provide system-specific control commands to pumps, solenoid valves or switch relays. The housing cover is sealed with an O-ring. Due to the factory-mounted and shrunk cable and agglutinated cover protection class IP68 as well. eleCTRiCAl DATA rating V AC max. voltage V bis 250 V 24 V max. current A (microswitch) 6A WiRing DiAgRAm V DC induktiv V DC resistive 2A 24 V 2A (Din en 50005) 2 4 1 Alter Hafen Nord 216 + 18069 Rostock + Fon: +49 381-202 60 800 + Fax: +49 381-202 60 809 + www.uad-online.de + [email protected] Dimensions (TANK) Welding Flange (Examples) D Schwimmerschalter LSG level switch LSG 75 75 56 56 92 92 Prüftaster button test 80 80 Flansch-n und Bohrbild nach Kundenanforderung n65 d 2 d Kabelverschraubung ca. 180 k cable gland 15 15 ca. 180 152 152 D 75 75 56 56 92 92 level switch LSG Schwimmerschalter LSG 80 80 Flansch-n und Bohrbild nach Kundenanforderung n65 d d2 Kabelverschraubung cable gland 15 15 ca. 180 ca. 180 152 k 152 D ca.58 mm ca. 58 mm Y Y d2 k xX d Contact ca.58 mm ca. 58 mm UAD Service + Vertriebs UG [Haftungsbeschränkt] Alter Hafen Nord 216 18069 Rostock Germany V V t f +49 381. 202 60 800 +49 381. 202 60 809 e [email protected] WW Alter Hafen Nord 216 + 18069 Rostock + Fon: +49 381-202 60 800 + www.uad-online.de Fax: +49 381-202 60 809 + www.uad-online.de + [email protected]
