5 MODEL 140, 141, 142 SECTION 1.0 INSTALLATION SECTION 1.0 INSTALLATION 1.1 INSPECTION. Inspect the shipping container for damage. If damage is found, contact the carrier immediately. Inspect the sensor. Make sure all items on the packing list are present and in good condition. Notify the factory if parts are missing. NOTE Save the original packing carton and materials. Most carriers require proof of damage from mishandling. Use the original packing carton when returning the sensor to the factory. Refer to Section 4.0 for instructions. Improper installation and poor maintenance of the sensor are the major causes of measurement problems. The importance of careful adherence to the installation and maintenance instructions in this manual cannot be overemphasized. 1.2 MECHANICAL INSTALLATION Location Selection 1. Select a location where the sample is representative of the process. 2. Avoid dead ends or pipe stubs or any locations where circulation may be poor. 3. Ensure that the stream velocity at the point of installation is not so great as to distort or damage the sensor. 4. Where the stream velocity is low, mount the sensor so that the flow enters the end of the sensor and leaves through the vents in the side. This gives the greatest exchange of solution and the fastest response to conductivity changes. 5. Installing the sensor is a horizontal orientation is recommended to prevent interference by air or sludge entrapment. Generally, vertical downward mounting is not recommended due to air entrapment. Vertical upward mounting in the bottom of the pipe is also not recommended as it may allow the cell to accumulate sediment (see Figure 1-1). 6. Mount the sensor so that the liquid contacts the sensor to the pipe threads. FIGURE 1-1. Sensor Orientation Model 140 Sensor* Installation. The sensor is installed in either a 1-in. NPT weldalet or pipe tee (see Figure 1-2 for part nomenclature and installation information). **Install the sensor as follows: 1. Make sure that the distance between the sensor and analyzer/transmitter is within the limits specified in the instrument instruction manual. 2. Remove plastic shipping cap from the tip of the sensor. 3. Install the 1-in. NPT hex nipple into the weldalet or Tee as illustrated. (Figure 1-2). Use Teflon pipe tape on the pipe threads. 4. Position the entire sensor for easy access to the ball valve handle, sensor compression fitting nut and J-box terminal block. 5. Make sure the ball valve is in the fully open position. 6. Finger tighten the sensor compression fitting nut. Do not overtighten the sensor compression fitting nut because the next step is to press the sensor into the process pipe. 7. Set the sensor tip no closer than 1 inch from the far wall of the process piping. (See Figure 1-2). 8. Tighten the sensor compression fitting nut to hold sensor tip in position. See Figure 1-2 for sensor compression fitting tightening instructions. * With Ball Valve Kit (PN ) ** If installing a Model 140 sensor through a ball valve already in place, refer to Section

8 MODEL 140, 141, 142 SECTION 1.0 INSTALLATION 1.3 ELECTRICAL INSTALLATION. The following diagrams are for wiring Model 140 Series conductivity sensors to various instruments (see Table 1-1 to find the appropriate wiring diagrams). Models 140, 141, and 142 include a sensor-mounted junction box (see Figure 1-5a). Extension cable PN (unprepped) or PN (prepped as shown in Figure 1-5b) must be ordered separately for these models. See Figure 1-5b for wire functions. See Figure 1-6 for wiring extension cable to the terminal block inside a sensor-mounted junction box. For example, to wire a 140 sensor to a 54eC analyzer, connect one end of the extension cable to the sensor-mounted junction box (Figure 1-6) and the other end to the analyzer (Figure 1-7). After wiring, install the cover on the junction box making sure that the gasket is properly seated. The sensor is now ready for operation. Please refer to the analyzer/transmitter manual for instrument calibration procedures. TABLE 1-1.

12 MODEL 140, 141, 142 SECTION 2.0 MAINTENANCE SECTION 2.0 MAINTENANCE 2.1 GENERAL. Rosemount Analytical recommends regular inspection of in-service conductivity sensors. Conditions of service and the magnitude of the conductances being measured will determine the frequency of inspection. In general the more conductive the liquid and the higher the level of suspended solids, the more often inspection is required. Any unusual behavior, not attributable to known variations in the process, should be taken as an indication that the sensor requires maintenance. Periodic inspection should answer the following questions: 1. Are there cracks or chips in the sensors or any signs of wear? 2. Are the flow holes free from obstruction? 3. Is there indication that excessive stream velocities have caused erosion or changes in the position of the electrodes? 4. Do the electrodes show signs of corrosion or deterioration? 5. Is the leakage resistance of the dry electrodes (measured between the drive and sense leads) at least 50 megohms? 6. Does the resistance across the temperature compensation wires match the temperature vs. resistance values in Table 2-1 (Section 2.2.1)?

13 MODEL 140, 141, 142 SECTION 2.0 MAINTENANCE 2.2 MODEL 140. Remove the sensor as follows: WARNING When retracting the sensor through a ball valve, the system pressure must be less than 100 psig (791 kpa). System pressure may cause the sensor to retract with great force. Make sure the following steps are performed carefully. 1. Push in on the sensor J-box and slowly loosen the sensor compression fitting nut (reversing the sensor tightening procedure illustrated in Figure 1-2). 2. When the sensor compression nut is completely unscrewed, slowly ease the sensor out until the flared tip of the electrode rests firmly within the compression fitting body. 3. Close the ball valve completely. CAUTION Before removing the sensor, make sure the ball valve is fully closed. 4. Unscrew the compression fitting body from the reducing bushing and remove the sensor from the ball valve assembly. The sensor may now be serviced Temperature Compensation Check. To insure that the temperature compensation circuit is operating correctly, perform the following check: 1. With the the instrument leads disconnected, connect an ohmmeter across the two red leads of the sensor. 2. The temperature in Table 2-1 should produce the corresponding resistance readings. If process temperature is not known, remove the sensor from the process. Have a thermometer next to the probe tip to indicate the temperature. 3. If the temperature compensation element does not respond accurately the sensor should be replaced. PT 100 T.C.

14 MODEL 140, 141, 142 SECTION 2.0 MAINTENANCE Electrode Check. The sensor may be checked for electrode stability and operating condition by performing the following check: 1. With the sensor removed from the sensor system and instrument leads disconnected, clean the tip of the probe with a 10% solution of nitric acid or mild solvent. Rinse thoroughly with distilled or deionized water and then dry completely. 2. Connect an ohmmeter across the black and white leads of the sensor. 3. With the probe dry and clean, the resistance should read from 10 megohms to an excess of 100 megohms. The sensor will be operational with a reading as low as 10 megohms, but its service life may not be long. It should be checked and the reading recorded weekly and. If the deterioration continues, the sensor should be replaced. 4. Continuity Check: Measure resistance from TB1-4 in the junction box and the outer electrode and from TB1-5 in the junction box and the inner electrode. Both should be zero ohms (see Figure 2-2). NOTE Make sure the tip of the probe is dry; the reading can be affected by moisture Model 140 Retraction Restraint Check. The integrity of this system, will become compromised if the flared tip of the electrode is allowed to blowout against the compression fitting body. In the event that a blowout occurs, replace the sensor with a new assembly. Parts may be ordered from Rosemount Analytical (see Section 3.2, for replacement parts and accessories). DWG. NO. REV J FIGURE 2-2. Sensor Continuity Check 10

15 MODEL 140, 141, 142 SECTION 2.0 MAINTENANCE Process Seal Maintenance. If the process seal is leaking due to a pitted or uneven sensor tube, a replacement sensor is required (see Section 3.2, for replacement parts and accessories). If the sensor tube surface is smooth and clean yet the process seal is leaking, the process O-ring is damaged and requires replacement according to the following procedure (see Figure 2-1). Replacement parts can be obtained from the Process Fitting Rebuild Kit (PN ). 1. The junction box with attached compression fitting body, nut and compression fitting must be recovered from the sensor for reuse. Unscrew the junction box cover and set aside. Mark and disconnect the electrical connections from the terminal block. Remove the junction box compression fitting nut from the compression fitting body and separate the junction box from the sensor tube. 2. Remove the nylon ferrule and snap ring (discard both). Remove and save the junction box compression fitting nut. 3. Slide off the sensor compression fitting nut and set aside for reuse. Slide off the remaining PEEK ferrule and split ring (discard both). 4. Remove the sensor compression fitting body and replace the Viton O-ring. Lubricate the O-ring with the Barium based lubricant provided. 5. Cover the pipe threads of the sensor compression fitting body with Teflon tape and slide it on to the sensor tube. 6. Slide on a new PEEK ferrule, beveled side facing the electrode tip, and a new PEEK split ring, flared end towards electrode tip. Slide on the sensor compression fitting nut and thread it onto the compression fitting body. Finger tighten. 7. Reinstall the J-box on the sensor tube. Finger tighten the J-box compression fitting nut. Use a wrench to turn the nut a 1/4 to 1/2 additional turn Sensor Insertion. Insert the sensor into the ball valve as follows: CAUTION Make sure process O-ring is clean, lubricated, and in place before installing sensor. Replace if worn. 1. DO NOT open the ball valve. WARNING The system pressure must be less than 100 psig (791 kpa). 2. Thread the sensor compression fitting body into the reducing bushing in the rear of the ball valve and tighten. NOTE Do not push past this point. Damage to the sensor could result. WARNING If the sensor comes free of the valve, refer to Figure 2-1 and verify that the valve and associated fittings are as shown. Do not proceed until the sensor is correctly restrained. 3. Slowly open the valve. WARNING Stand clear of the sensor. 4. Insert the sensor up to the desired insertion depth and turn the sensor compression fitting nut until it is finger tight. 5. Position the entire sensor for easy access to the ball valve handle, sensor compression fitting nut and J-box terminal block. 6. Tighten sensor compression fitting nut. CAUTION For initial installation of the sensor, tighten the compression fitting nut 1-1/4 turns after finger tight. If it is a reinstallation, turn no more than 1/4 to 1/2 additional turns! 11

16 MODEL 140, 141, 142 SECTION 2.0 MAINTENANCE 2.3 MODEL 141. Make sure the system pressure is shut off and remove the sensor as follows: WARNING Process flow or pressure must not be present. 1. Unscrew the sensor at the pipe fitting or weldalet. 2. Make sure the tip of the probe is dry; the reading can be affected by moisture. 3. Check the temperature compensation element as instructed in Section Check the electrodes as instructed in Section 2.2.2, steps Install the sensor into process fitting. Use Teflon tape on the pipe threads. 2.4 MODEL 142. Make sure the system pressure is shut down and remove the sensor as follows: WARNING Process flow or pressure must not be present. 1. Loosen the process fitting and slowly slide the sensor from the pipe fitting or weldalet. 2. Check the temperature compensation element as instructed in Section Check the electrodes as instructed in Section 2.2.2, steps Install the sensor by sliding the probe into process fitting and position the probe as in the original installation. CAUTION Make sure the probe is in the same position as originally installed. The probe takes a permanent set and could be weakened if set is adjacent to original set. 5. Tighten sensor compression fitting nut 1/4 to 1/2 turn after finger tight. 2.5 TROUBLESHOOTING. Following the instructions under maintenance should keep the sensor in good operating condition. If, however, a problem should arise, consult the instrument or transmitter manual for explanation of diagnostic errors. Rosemount analyzers and transmitters (except the Model 1181C) have a diagnostic feature that automatically searches for fault conditions that cause errors in the measured conductivity. If more than one fault exists, the display sequences through all the diagnostic messages. 12

MEASUREMENT RANGES FROM 0-1 µs/cm to 0-20,000 µs/cm. 3.1 FEATURES AND APPLICATIONS. The Rosemount Analytical Model 140, 141, and 142 conductivity sensors are designed for measuring conductivity in high temperature and pressure applications. A choice of cell constants allows measurements in low to medium conductivity level samples. The sensors corrosion-resistant 316 stainless steel construction and ability to be inserted directly into a process line or through the side of a vessel make them rugged and easy to install and maintain. The Model 140 retractable conductivity sensor simplifies sensor installation and maintenance because it can be removed from a pressurized line or vessel without shutting down the process or using bypass sample lines. The sensor s measuring electrodes are inserted into process through a 1 inch ball valve and a Viton 1 process seal. To retract the sensor, a retaining nut is loosened, the sensor backed out of the process and the ball valve closed. The standard Model 140 is constructed of 316 stainless steel and PEEK and can operate up to 150 C. High temperature options (Codes 05, 07, 55, or 57) must be selected to measure up to 200 C. The choice of a 0.2 or 1.0 cell constant allows conductivity measurements up to 20,000 µs/cm with the Rosemount Analytical Model 54eC, 1055, 1054B C, 1054B R, 1181C and 2081C, 3081C, and 81C analyzers. The Model 141 Insertion Sensor measures conductivity in high temperature, high pressure applications. The standard Model 141 is constructed of 316 stainless steel and PEEK and can operate at temperatures up to 150 C. An optional high temperature version (Code 14) can operate at temperatures up to 200 C. The choice of a 0.2 or 1.0 cell constant allows conductivity measurements up to 20,000 µs/cm with the Rosemount Analytical Model 54eC, 1055, 1054B C, 1054B DC, 1054B R, 1181C, 2081C, 3081C, and 81C analyzers.
