4 Mechanica Leve Switches Principes FoatOperated Leve Switches Mode Series 100, 200 and 300 The foat rides on the process iquid surface, precisey tracking iquid surface motion. Rising iquid eve ifts the foat, siding the attraction seeve up inside the encosing tube and into the magnetic fied to actuate the eectrica or pneumatic switch (signaing iquid presence). Subsequenty, faing iquid eve owers the foat, drawing the attraction seeve out of the magnetic fied to deactuate the eectrica or pneumatic switch (signaing iquid absence). Foattype eve switches are generay abe to hande hightemperature appications, and sometimes prove usefu for cose interface detection. Foats can operate up to three switching eements. Independent switching eves may be obtained with tandem foats. Consut the factory for specia foatswitching arrangements.

5 Mechanica Leve Switches Principes DispacerOperated Leve Switches Mode Series 700, 730, 740, 750 and 800 Dispacer contros offer aternative features to the foatoperated contro. The sensor is a weight (dispacer), heavier than the iquid, that is suspended by a spring. When iquid contacts the dispacer, a buoyancy force is produced, which causes the effective weight of the dispacer to change. This causes the spring to retract sighty to a new equiibrium position. When the spring retracts, the attraction seeve aso moves upward into the fied of the externa magnet, thus overcoming the force of the bias spring and actuating the switching eement. This principe provides for narrow or wide switching differentia, and aows switching point ateration by moving the dispacer(s) up or down the suspension cabes. Dispacers may be arranged in combinations of narrow and wide differentia to operate up to three switching stages. Dispacer contros operate under higher pressure conditions than foatoperated switches.

51 Mechanica Leve Switches High Temperature Seection SOR eve switches can accommodate hightemperature appications up to 1200 o F (649 o C). These temperatures may be safey reached by a proper combination of chamber materia, switch mechanism and temperature extension. Refer to page 52 to seect the proper components for your process temperature. ET Accessory The straight temperature extension provides physica distance between the process and the switching mechanism. It is constructed of a straight piece of pipe weded between the chamber and encosing tube connection. How It Works The straight temperature extension is designed to remove the switch from direct radiant heat in dry heat processes. Consut the chart on page 52 for appication. To Specify Add Accessory Designator ET to the end of the SOR eve switch mode number per the seection chart on the next page. The ET accessory automaticay matches the materia and rating of the specified eve switch chamber. This option can be suppied on SOR eve switches Series 100, 200, 300 and A A1CBA1N4ET TT FE Accessories 201 A A1CBA1N4FE TT The finned temperature extension is designed to protect the eectrica portion of a eve switch from heat damage due to condensing processes. When used in combination with hightemperature switch mechanisms, this option aows operation in process temperatures up to 1200 o F (649 o C). How It Works The finned temperature extension condenses process steam and reduces its heat before it can reach the switching mechanism. The design reduces steam to its saturation temperature in the encosing tube, protecting the switching mechanism from deterioration due to high temperatures. The process pressure dictates the saturation temperature, see page 58. To Specify Add Accessory Designator FE to the end of the SOR eve switch mode number per the seection chart on the next page. The finned temp. extension automaticay matches the materia and rating of the specified eve switch chamber. These options can be suppied on SOR eve switches series 100, 200,108/208, 300 and 400. Note: For proper cooing, temp. extensions must not be insuated or paced inside an encosed structure. High ambient temperatures (over 100 o F/38 o C), intense direct sunight, or heat oading from adjacent piping or vesses wi affect cooing performance. Consut the factory if any of these conditions exist. Drawing Registered Quaity System to ISO 9001: /60

52 Mechanica Leve Switches High Temperature Seection There are two sections to the chart, Steam Heat and Dry Heat. Fundamenta differences in condensing (steam) and noncondensing (dry) heat require different methods of protection. Steam Heat processes carry it s heat with the vapor. These processes effectivey heat every portion of their encosure. To reduce the heat effects of condensing processes, we must either condense or physicay bock the vapor. SOR uses a condensing system to avoid the seaing probems associated with bocking the steam. Dry Heat processes transfer heat through direct conduction. Heat is ony passed to the areas where they touch the encosure. Therefore, radiant heat is the ony concern with these processes. This may be resoved by adding distance between the process and the protected portion of the contro. To use the seection chart, first seect the coumn that represents the desired maximum temperature.

54 Mechanica Leve Switches Examination and Testing Requirements 741A A1CBA1CYCRTT Certificate of Conformance Specify either a CY or CZ option in the accessory section of the mode number for a certificate of conformance. Designator CY CZ Certificate of Conformance to ASME/ANSI B31.1 Power Piping ASME/ANSI B31.3 Petrochemica Piping If certification to B31.3 is required, SOR must know the fuid category per the chart beow. Refer to the ASME/ANSI B31.3 Fuid Category Section to determine the appicabe category. ANSI/ASME B31.3 Fuid Category Norma A fuid service not subject to the foowing four categories. Category D A fuid service in which a of the foowing appy: 1. The fuid handed is nonfammabe, nontoxic, and not damaging to human skin. 2. The design gage pressure does not exceed 150 psi. 3. The design temperature is between 20 F and 366 F. Category M A fuid service in which the potentia for personne exposure is judged to be significant and in which a singe exposure to a very sma quantity of a toxic fuid, caused by eakage, can produce serious irreversibe harm to persons on breathing or bodiy contact, even when prompt restorative measures are taken. Severe Cycic A fuid service with highcyce rates that cause extreme stress on components. High Pressure Pressure in excess of that aowed by the ASME B16.5 Cass 2500 rating for the specified temperature and materia group or any piping so designated by the customer. Wed Examination When CY or CZ is specified, SOR performs examination to meet these codes. This incudes visua inspection and utrasonic, Xray, magnetic partice or dye penetrant testing as required by ASME B31.1 or B31.3. If CY or CZ is not seected but examination is required, accessories UT (utrasonic), RT (Xray), MT (magnetic partice) or PT (dye penetrant) can be added to the mode number to incude this testing. Hydrostatic Testing SOR performs a hydrostatic pressure test on a weded chambers at 1.5 times the design pressure for three minutes. CY and CZ options and Hydrotest Certificates incude a hydrostatic pressure test at 1.5 times the design pressure for ten minutes as required by ASME B31.1 and B31.3 codes. A hydrostatic test certificate is aso avaiabe as an accessory. See Test Certificates, Form /60 Registered Quaity System to ISO 9001:2008

55 Mechanica Leve Switches MC and TC Options 702AAICBA1MCCRTT Manua Check (MC) and TruCheck (TC) options permit manua actuation of vertica dispacer eve switches, addressing EPA and OSHA safety requirements. The standard 30foot stainess stee chain aows manua actuation from the tank base, eiminating potentiay hazardous trips to the top of the tank. Specify either an MC or TC option by pacing the designator in the accessory section of the mode number. Designator TC MC Appication Tanks or vesses pressurized to 100 psi Atmospheric vented tanks or vesses These options are avaiabe on SOR eve switch Series 701 through 704 and 730 through 733.
