4 Mechanical Level Switches Principles FloatOperated Level Switches Series 100, 200 and 300 The fl oat rides on the process liquid surface, precisely tracking liquid surface motion. Rising liquid level lifts the fl oat, sliding the attraction sleeve up inside the enclosing tube and into the magnetic fi eld to actuate the electrical or pneumatic switch (signaling liquid presence). Subsequently, falling liquid level lowers the fl oat, drawing the attraction sleeve out of the magnetic fi eld to deactuate the electrical or pneumatic switch (signaling liquid absence). Floattype level switches are generally able to handle hightemperature applications, and sometimes prove useful for close interface detection. Floats can operate up to three switching elements. Independent switching levels may be obtained with tandem fl oats. Consult the factory for special fl oatswitching arrangements.

Rising liquid level lifts the fl oat via a pivot mechanism, sliding the attraction sleeve down inside the enclosing tube and out of the magnetic fi eld to deactuate the electrical or pneumatic switch (signaling liquid presence). Subsequently, falling liquid level lowers the fl oat, drawing the attraction sleeve into the magnetic fi eld to actuate the electrical or pneumatic switch (signaling liquid absence).

5 Mechanical Level Switches Principles DisplacerOperated Level Switches Series 700, 730, 740, 750 and 800 Displacer controls offer alternative features to the fl oatoperated control. The sensor is a weight (displacer), heavier than the liquid, that is suspended by a spring. When liquid contacts the displacer, a buoyancy force is produced, which causes the effective weight of the displacer to change. This causes the spring to retract slightly to a new equilibrium position. When the spring retracts, the attraction sleeve also moves upward into the fi eld of the external magnet, thus overcoming the force of the bias spring and actuating the switching element. This principle provides for narrow or wide switching differential, and allows switching point alteration by moving the displacer(s) up or down the suspension cables. Displacers may be arranged in combinations of narrow and wide differential to operate up to three switching stages. Displacer controls operate under higher pressure conditions than fl oatoperated switches.

51 Mechanical Level Switches High Temperature Selection SOR level switches can accommodate hightemperature applications up to 1200 o F (649 o C). These temperatures may be safely reached by a proper combination of chamber material, switch mechanism and temperature extension. Refer to page 52 to select the proper components for your process temperature. ET Accessory The straight temperature extension provides physical distance between the process and the switching mechanism. It is constructed of a straight piece of pipe welded between the chamber and enclosing tube connection. How It Works The straight temperature extension is designed to remove the switch from direct radiant heat in dry heat processes. Consult the chart on page 52 for application. To Specify Add Accessory Designator ET to the end of the SOR level switch model number per the selection chart on the next page. The ET accessory automatically matches the material and rating of the specifi ed level switch chamber. This option can be supplied on SOR level switches Series 100, 200, 300 and A A1CBA1N4ET TT FE Accessories 201 A A1CBA1N4FE TT The fi nned temperature extension is designed to protect the electrical portion of a level switch from heat damage due to condensing processes. When used in combination with hightemperature switch mechanisms, this option allows operation in process temperatures up to 1200 o F (649 o C). How It Works The fi nned 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 enclosing 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 level switch model number per the selection chart on the next page. The fi nned temp. extension automatically matches the material and rating of the specifi ed level switch chamber. These options can be supplied on SOR level switches series 100, 200,108/208, 300 and 400. Note: For proper cooling, temp. extensions must not be insulated or placed inside an enclosed structure. High ambient temperatures (over 100 o F/38 o C), intense direct sunlight, or heat loading from adjacent piping or vessels will affect cooling performance. Consult the factory if any of these conditions exist. Drawing Registered Quality System to ISO 9001: /60

52 Mechanical Level Switches There are two sections to the chart, Steam Heat and Dry Heat. Fundamental 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 effectively heat every portion of their enclosure. To reduce the heat effects of condensing processes, we must either condense or physically block the vapor. SOR uses a condensing system to avoid the sealing problems associated with blocking the steam. High Temperature Selection Dry Heat processes transfer heat through direct conduction. Heat is only passed to the areas where they touch the enclosure. Therefore, radiant heat is the only concern with these processes. This may be resolved by adding distance between the process and the protected portion of the control. To use the selection chart, fi rst select the column that represents the desired maximum temperature. Select a chamber material that is allowable in the chosen column. Move down to the proper process type section, Steam Heat or Dry Heat. Within that section, select a switch mechanism from those listed in the chosen column. The symbol will indicate if a temperature reduction device is required.

55 Mechanical Level Switches MC and TC Options 702AAICBA1MCCRTT Manual Check (MC) and TruCheck (TC) options permit manual actuation of vertical displacer level switches, addressing EPA and OSHA safety requirements. The standard 30foot stainless steel chain allows manual actuation from the tank base, eliminating potentially hazardous trips to the top of the tank. Specify either an MC or TC option by placing the designator in the accessory section of the model number. Designator TC MC Application Tanks or vessels pressurized to 100 psi Atmospheric vented tanks or vessels These options are available on SOR level switch Series 701 through 704 and 730 through 733. MC and TC option available on carbon steel units only. How It Works Pulling the handle transfers downward motion to the actuator lever by means of the beaded stainless steel chain. The resultant motion lifts the entire level sensing assembly which moves the attraction sleeve and actuates the switching element to simulate a highlevel condition. Switching action for alarm, shutdown or control is verifi ed.

57 Mechanical Level Switches Specific Gravity of Water The specifi c gravity of water changes depending on its temperature and pressure. The chart below lists properties of saturated steam. Saturated steam is the state where water is in transition between liquid and vapor. The chart provides the process temperature with the associated pressure and specifi c gravity of the condensate water. If a water application has a high temperature and low pressure, condensate will only be present at the temperature that corresponds to the maximum pressure. Select the proper row based on the temperature and pressure, and read the specifi c gravity. Figures are based on saturated steam.
