The 242 Flow Through Toroidal conductivity sensor consists of two toroids surrounding a pipe through which the process liquid flows. One toroid acts as a transmitter and the other as a receiver. Energizing the transmitter toroid induces an electric current in the process solution which induces an electric current in the receiver toroid. The strength of the induced current is directly proportional to the conductivity of the solution. The 242 sensor is available in over two hundred fifty configurations to meet the needs of many applications and installations. Line sizes of 1, 1.5, 2, 3, and 4 inches (25, 40, 50, 80, and 100 mm) are available with both ANSI and DIN compatible flanges. A variety of liner materials and O-rings are available to ensure compatibility with most process liquids. The 242 sensor is easy to install. It fits in the process piping between mounting flanges. Special grounding rings are not needed because the sensor has contact rings built into it. Recessed bolts hold the sensor together to ensure all internal parts stay in perfect alignment. A junction box and a Pt 100 RTD are included. The RTD slips easily into one of the sensor contact rings. There is no need to install a separate thermowell, and temperature measurements are made at the same point as the conductivity measurements. The sensor is not sensitive to flow rate or direction. It does not obstruct the process flow. The sensor is rugged and constructed from chemically resistant materials. All these features make the sensor ideal for applications in mining and metals processing, pulp and paper processing, and the chemical processing industry. The 242 Flow Through Conductivity Sensor is compatible with instrument instumentsL 54eC, 1055, 3081T, 4081T, 5081-T, and Xmt-T. 1 MODEL 242 SECTION 1.0 MODEL 242 SENSOR 1.2 SPECIFICATIONS The Model 242 Flow Through Sensor comprises a toroid housing constructed from 316 stainless steel and polyethyleneterephthalate, process connection flanges of 316 stainless steel, two metal contact rings (available in choice of three materials), an insulating liner (choice of three materials), O-rings (choice of three materials), a Pt 100 RTD, and a sensor-mounted junction box. Only the liner, contact rings, and O-rings are wetted by the process. The Pt 100 RTD is designed for insertion into one pre-drilled contact ring. The NEMA 7D junction box is constructed of heavy duty epoxy-painted cast aluminum. The conductivity range is user-selectable with the tapped toroid windings. In-line calibration can be performed with resistors connected to an integral wire around the toroids that is terminated in the junction box. Pt 100 RTD Flange Contact Ring Liner O-ring (not visible) Liners are available in Teflon, glass-filled Polyetheretherketone (PEEK), and alumina. These materials provide excellent chemical resistance. PEEK is recommended for high pressure or high temperature applications. Teflon is recommended when the process solution contains hydrofluoric acid or other strong oxidizing agents. Alumina is recommended if the process solution is abrasive, such as in alumina/caustic ratio applications. Installation Type Flow Through Conductivity Range 100 μS/cm to 2 S/cm Process Connections 150# ANSI, 300# ANSI, PN16 DIN 2501 compatible flanges Maximum Temperature Depends on configuration.

If appropriate for the site and final mounting configuration, the Junction Box can be installed prior to bolting the sensor into the process line. CAUTION The liner of the Model 242 sensor can be damaged if mishandled. Do NOT place any object through the liner for the purpose of lifting the Model 242 sensor. CAUTION Support structures should be installed as appropriate on or around process pipes and sensor location to sufficiently support the weight of the sensor during installation and minimize strain on adjacent process pipes during the operational life of the sensor. Installation of the Model 242 Flow Through Sensor is similar to installation of a section of pipe. Consequently, be prepared to use tools, supplies, equipment, and techniques similar to those used to install process pipes. Use common piping practices to minimize torque and bending loads on process connections. Observe all applicable safety standards. Dimensional information is shown in Figure 1-5 below. Refer to Figures 1-6 to 1-8 for assembly and installation diagrams. NOTES 1. Allow at least four pipe diameters of straight pipe run on either side of the sensor. 2. Install the sensor so that it is filled with process liquid at all times when measurements are being made. Avoid downward flow as such a configuration might leave the sensor partially empty. 3. Use a sling and hoist to lift and position the sensor. INCH MILLIMETER FIGURE 1-5. DIMENSIONAL DRAWING 7 MODEL 242 SECTION 1.0 MODEL 242 SENSOR INSTALLING THE SENSOR IN THE PROCESS LINE 1. Install process flanges in accordance with applicable instructions, standards, and local regulations. 2. Position the sensor between the process mating flanges with flange gaskets inserted between each set of flanges. Ensure that the locations of the junction box connection and the RTD hole in the contact ring are in the correct position for easy wiring and use. 3. Align the bolt holes in the sensor and process flanges. 4. Lubricate the bolt threads. Using a torque wrench, bolt the sensor into place. Tighten the bolts in 1/3 increments of the final desired torque. Follow the bolt-tightening sequence and torque suggestions provided in Figure 1-6. 5. Re-torque the bolts 12 to 24 hours after installation. Make a final check of torque values by moving consecutively from bolt to bolt. Torque values in the table above are from Garlock Sealing Technologies. Other values might apply when using different bolt and gasket materials.

Pull the sensor wires up into the junction box. Screw the junction box onto the threaded male connection on the sensor. Use of pipe sealing tape or other compound is at the discretion of the customer. Connect the sensor wires to the junction box terminal as indicated in Figure 1-7. INSTALLING THE Pt100 RTD 1. 2. 3. 4. 5. Use of the included Pt100 RTD is recommended. Use of a customer-supplied Pt100 or Pt1000 TC mounted in a separate thermowell is also acceptable. The accuracy specifications provided by Rosemount Analytical apply only to situations wherein the Pt100 RTD supplied with the sensor is used. Refer to Figure 1-8. Screw the threaded nipple onto the conduit connector of the junction box. Screw the tee onto the nipple, and screw the RTD cable connector onto the tee. Attach the bracket to the shaft of the RTD using the #10 washer and small screw enclosed in the RTD kit.

Install the white jumper wire between terminals 1 and 2. Items 1-9 are included with the Model 242 sensor. Items 3-9, the white jumper wire, and Teflon tape are included in the TC kit. Items 10 and 11 are sold separately as accessories. FIGURE 1-8. Sensor/J-box/RTD Assembly 9 MODEL 242 SECTION 1.0 MODEL 242 SENSOR EXTENSION CABLE HOOK UP 1. Do not run sensor cable in conduit or open trays with A.C. power wiring. Do not route sensor cable near heavy electrical equipment. 2. For best sensor/instrument loop performance, use factory-terminated extension cable (PN 23909-00). (Using a different cable can introduce noise into the signal and/or reduce loop accuracy.) 3. One end of extension cable (PN 23909-00) has 8 wires, and the other end has 11 wires. Refer to Figure 1-9. The end with 8 wires goes into the junction box. The end with 11 wires goes to the instrument. The extension cable enters the junction box through the open side of the female threaded tee. Use of conduit, the optional cable connector (PN 9310137), or other strain relief device to protect the cable is at the discretion of the customer and should comply with applicable agency guidelines. NOTE If starting with unprepped cable (PN 9200276), remove only as much insulation as is necessary. The instrument end needs 11 leads: four leads from the greenwhite-black-drain bundle, three from each of the two coaxial cable bundles (the inner conductor, the insulating braid, and the drain wire), and one from the outermost overall braided-copper shield. For the junction box end, only 8 leads are used: the white coaxial conductor, its braided shield, the green coaxial conductor, its braided shield, its drain wire, and the green, white, and black conductors from the green-white-black-drain bundle. The remaining shields and drain wires are not used on the junction box end and should be removed - they should NOT be connected. 4. Connect the 8 wires of the extension cable to the terminal block inside the sensor junction box as indicated in Figure 1-7. Note: If all process measurements will be less than 10,000 µS/cm, connect the green wire from the black-green-clear wire bundle of the extension cable to the terminal receiving the orange sensor wire. See Figure 1-7. 5. Connect the 11 wires of the instrument-end of the extension cable according to the applicable diagram from Figures 1-10 through 1-15. 1.5 CALIBRATION After sensor and transmitter/analyzer wiring is completed, calibrate the sensor. NOTE Most analyzers require the input of the approximate sensor cell constant before the analyzer calculates the true cell constant. The nominal cell constant of the Model 242 sensor depends on the size of the sensor and the terminal to which the receive wire of the interconnecting cable is attached. Refer to Table 1-1 for the appropriate nominal cell constant value. TABLE 1-1: Nominal Cell Constants for 242 Sensors Sensor Size 1”, DN 25 1.5”, DN 40 2”, DN 50 3”, DN 80 4”, DN 100 Cell Constant (/cm)* Black Orange 20 2.0 9.0 0.90 5.0 0.50 4.0 0.40 2.3 0.23 * The table gives the cell constant when the green receive wire (from black-green-clear bundle) of the interconnecting cable is attached to either the black wire terminal or the orange wire terminal in the sensor junction box. See Figures 1-7 and 2-1. FIGURE 1-9. Extension Cable 10 MODEL 242 SECTION 1.0 MODEL 242 SENSOR FIGURE 1-10. Extension Cable to Model 54eC Wiring NOTE: If wiring to a single channel 1055-21 or to a dual channel 1055-21-xx or 1055xx-31, the toroidal sensor is wired only to Terminal Blocks 3 and 4. If wiring 2 sensors to a dual toroidal 1055-21-31, use TB 3, 4, and 5 as shown. FIGURE1-11.

To perform liquid calibration prior to installing the sensor in the process line, first seal one end of the sensor, and then proceed with the following steps. 1. Stand the sensor on the sealed end. 2. Fill the sensor completely with a standard conductivity solution. 3. Insert the Pt100 RTD into the contact ring. 4. Adjust the analyzer reading so that it matches the conductivity of the standard solution at the solution temperature. Refer to the analyzer/ transmitter instruction manual for complete calibration procedures. B. Use of the Integral Calibration Loop Wire: This internal wire can be used to facilitate future in-process loop calibration and to perform a quick verification that the loop is functioning properly. Performing this additional (but optional) step is highly recommended. 1. The sensor must be empty of all fluids, reasonably clean, and preferably completely dry. 2. Attach a variable resistance decade box to the sensor yellow “Cal Loop” wires (in the junction box). 3. Adjust the applied resistance until the instrument reads the same conductivity value that it did during the liquid calibration process. Record the conductivity, applied resistance value, and temperature for future reference. 4. To recalibrate the loop at a later date, optimal results will be achieved if the sensor is returned to a condition approximating its condition during the initial performance of steps C.1 to C.3 above. If this is not possible, the sensor must at least be empty of process fluids. Reapply the same resistance to the Cal Loop and adjust the instrument reading. 1.6 MAINTENANCE The only routine maintenance required during the operational life of the sensor is to ensure that there are no deposits plugging the sensor or coating the inside of the contact rings. Some customers find it advantageous to periodically replace process gaskets and/or re-tighten the flange bolts to ensure adequate process seals.

The simplest method of troubleshooting is to run a resistance test on the inductive sensing device. It is also recommended to check the resistance of the RTD and resistance between various pairs of the sensor wires. To perform a quick resistance check of the sensor, recall the data obtained during Part C of the Calibration Process (Refer to Section 1.5) With the sensor empty of process fluids (preferably also clean and dry), reapply the resistance to the sensor yellow Cal Loop wires in the junction box. The reading should be with ±20% of the original value. To check the RTD, measure the resistance across the RTD wires. See Figure 1-4. The resistance value should be close to the value shown in Table 2-1. Refer to Figure 2-1 for a circuit diagram of the sensor to use as an aid when performing the resistance checks. Use Table 2-2 to determine the resistance values that should be found across various pairs of sensor wires. TABLE 2-1 Resistance Values for Pt100 RTD Temperature (°C/°F) 18 / 64.4 106.9 19 / 66.2 107.3 20 / 68.0 107.7 21 / 69.8 108.1 22 / 71.6 108.4 23 / 73.4 108.9 24 / 75.2 109.2 25 / 77.0 109.6 26 / 78.8 110.0 27 / 80.6 110.4 C = Celsius / F = Fahrenheit TABLE 2-2 Sensor Wire Resistance Values Connection (Wire colors are for sensor wires unless indicated) GREEN to ORANGE GREEN to BLACK GREEN to GROUND screw in J-box (GRAY wire) GREEN to WHITE GREEN to YELLOW WHITE to GRAY WHITE to GROUND screw in J-box (GRAY wire) WHITE to YELLOW WHITE to RED YELLOW to YELLOW YELLOW to GROUND screw in J-box (GRAY wire) 14 Resistance (Ohms) Resistance < 1 Ohm 1 to 5 Ohms > 20 MegOhms > 20 MegOhms > 20 MegOhms < 1 Ohm > 20 MegOhms > 20 MegOhms > 20 MegOhms < 1 Ohm > 20 MegOhms MODEL 242 SECTION 2.0 MODEL 242 SENSOR *The green wire from the extension cable’s black-green-clear bundle might be connected opposite the sensor’s orange wire, as indicated by * to utilize the sensor’s alternative cell constant.

Replacement of original components with those constructed from alternative materials might change the temperature, pressure, and/or performance specifications from those of the original configuration and will void any CSA, FM, and BASEEFA/CENELEC agency approvals that were applicable to the original device. Table 3-1 lists the replacement parts kits for the Model 242 Sensor. An instruction manual is included with each kit. There are two pairs of O-rings inside the sensor: process O-rings (item 6) and secondary or backup O-rings (item 7). Refer to Figure 3-1 to identify these items. The two pairs of O-rings are not interchangeable. Older O-ring replacement kits contained only the pair of process O-rings. New O-ring replacement kits contain both pairs of O-rings. To distinguish the process O-ring from the backup O-ring: For sensors with plastic liners: CAUTION 1. The process O-ring has a much smaller cross sectional area than the secondary O-ring. The crosssection diameter of the process O-ring is 0.07 in. The cross-section diameter of the secondary O-ring is 0.139 in. Before removing the sensor from the process piping, ensure that the process has been shut down and liquid drained from the sensor line. For personal safety, 2. The diameter of the process O-ring is less than the secondary O-ring. The size difference is immediately obvious when the two O-rings are allowed to dangle from a pencil. 3.2 REMOVE THE SENSOR For sensors with alumina liners: 1. The process and secondary O-rings have the same cross sectional area. (0.139 in). The RTD can be removed either before or after the sensor is removed from the process. The junction box should be left attached to the toroid subassembly. After ensuring that it is safe to remove the sensor from the process line, loosen the flange bolts in 1/3 increments in the same order in which they were tightened as shown in Figure1-4. Remove the bolts and sensor. 3.3 DISASSEMBLE THE SENSOR Using the tool indicated in Table 3-2, remove the Sensor Bolts (Item 2). Note that these bolts were installed using a thread-locking adhesive. Any use of heat to loosen the adhesive should not exceed the temperature ratings of the sensor. Figure 3-1 is an exploded view of the all the parts of the Model 242 sensor. 16 2. The diameter of the process O-ring is less than the secondary O-ring. The size difference is immediately obvious when the two O-rings are allowed to dangle from a pencil. MODEL 242 SECTION 3.0 MODEL 242 SENSOR TABLE 3-1.

FIGURE 3-1. Exploded View of Model 242 18 MODEL 242 SECTION 3.0 MODEL 242 SENSOR 3.4 RE-ASSEMBLE THE SENSOR It is recommended that a press be used during the assembly process to ensure tight seals between components. Locate the part to be changed on the diagram and substitute the new part from the kit. Complete disassembly of the sensor might not be necessary and in that case is not recommended. If new O-rings are to be used, they should be lubricated prior to installation. Assuming the sensor has been completely disassembled, begin by placing both Contact Rings (Item 1) side by side on their flat faces. Set a Flange (Item 4) on each Contact Ring (Item 1). Install a Retainer Ring (Item 5) onto the step on the outside of each Contact Ring (Item 1). Insert a lubricated Process O-ring (Item 6) in the lower groove (closest to the flat face) located inside each Contact Ring (Item 1). Place a lubricated Secondary Back-up O-ring (Item 7) on the upper step inside each Contact Ring (Item 1). The flange-assembly should look like Figure 3-2. Place one of these flange-assemblies onto a press and install the Liner (Item 8). It is advisable to place a flat surface between the press and the liner to protect the liner from damage during pressing. Be careful to ensure O-rings do not slip or twist. Slip the Toroid Housing (Item 9) over the Liner (Item 8) to nest inside the flangeassembly. The pins on the toroid housing must seat into the small holes in the flanges. Place the second flangeassembly on top of the first flange assembly with the Liner (Item 8) and Toroid Housing (Item 9) in between. Check for pin alignment, pinched O-rings, and straight, even insertion. The Sensor Bolts (Item 2) can be temporarily preplaced in the bolt holes to align the two Flanges. Press the entire sensor together to begin assembly of all the components. Install and tighten the Sensor Bolts and Nuts (Items 2 and 3), using thread-locking compound. Using the torquing sequence shown in Figure 1-6, tighten the bolts in 1/3 increments of their final torque values as listed in Table 3-2.
