The following procedures should be performed by qualified technicians. Refer to the appropriate sensor maintenance instructions. Conductivity cells used in pure water service require little maintenance. ATTENTION SENSORS ARE STATIC SENSITIVE HANDLING PRECAUTIONS REQUIRED 2.2 MODEL SERIES. Remove the -02 series sensors in the following manner. CAUTION Be sure that removal of the sensor will not result in release of the process material. 1. The -11 and -13 models require a 1-1/8 inch wrench to unscrew the sensor body from the process container. The -15 requires a 1-3/8 inch wrench. 2. Inspect sensors for: condition of cable connections dented or bent sensor body extraneous material lodged between the electrodes. 3. To remove material without damaging the sensor. Blow off electrodes with a blast of compressed air. Rinse electrodes under a hot water tap. 4. For extremely dirty and/or fouled sensors: Use a warm 10% solution of either hydrochloric acid or sodium hydroxide (depending on the contamination). NOTE Do Not have the sensor powered during this procedure. When process clings to electrodes, insulators, and electrode holders, gentle brushing with a soft bristle brush (such as a toothbrush) may be employed. Continue rinsing for approximately one half hour. Wash the sensor in several changes of distilled or deionized water before reinstalling. NOTE Sensors cleaned by following the above procedure can be 95% accurate in 30 minutes, if there is sufficient process flow. Systems with slow flow may require up to 5 days before becoming 100% accurate. 5. Re-install as per Section MODEL SENSORS Remove the -03 series sensors in the following manner. CAUTION Be sure that removal of the sensor will not result in release of the process material. 1. Disconnect the tubing on the sensor housing to remove it from the process. 2. Inspect sensor for: condition of cable connections dented, cracked, or bent sensor body 3. To clean the sensor, slip a piece of tubing over the inlet and run hot tap water through the sensor cavity. 2.4 MODEL SENSORS CAUTION Be sure that removal of the sensor will not result in release of the process material. Remove the -04 series sensors in the following manner. 1. Stop process material entry into sensor housing by either bypassing the inlet or removing pressure from the housing inlet. WARNING Remove system pressure before attempting to remove knurled cap holding sensor in housing. 2. Remove piping from sensor housing. 3. Remove sensor from mounting. 4. Open sensor housing by unscrewing knurled top cap. 5. Remove inner electrode assembly sensor from the housing by pulling straight up. 2-1

10 MODEL 2701 SENSORS SECTION 2.0 MAINTENANCE 6. Inspect sensor for: condition of cable connections dented or bent sensor body seal condition dirty or fouled electrodes 7. If the housing needs cleaning, run hot tap water through the casing. 8. If the electrode needs cleaning, clean in the same manner as explained in Section Re-Install by: Inserting sensor into housing. Be particularly careful to insure O-rings are seated properly. Replace and hand tighten knurled cap. Install back into process as described in Section Model Sensors WARNING During removal, system pressure may cause the sensor tube 2 to extend with great force unless care is taken. Maintain adequate clearance when retracting the sensor. See Figure 1-5, dimension B for the distance from the nipple to the back of the sensor tube when in the withdrawn position. Follow the steps outlined in this section Remove the sensor tube from the ball valve as follows: 1. Be certain system pressure at the sensor is below 549 kpa (65 psig) before proceeding with the retraction. Always wear a faceshield and brace yourself in case the pressure forces the sensor tube 2 out of the ball valve Unscrew the large knurled nut 1 and withdraw the sensor tube 2 as far as possible by pulling back on the loosened nut. If the sensor tube cannot be retracted, loosen the set screws on the stop ring 6, pull the stop ring back, and slowly loosen the packing bushing 7 in 1/8 turn increments. Sensor tube may extend due to system pressure. If not, withdraw the sensor tube as far as possoble by pulling back on the loosened nut 1. Keep a firm grip on the sensor tube while withdrawing it in order to prevent sudden ejection. NOTE Failure to withdraw the sensor completely may result in damage to the sensor when the valve is closed. 3. Close the ball valve 3. WARNING Before removing the sensor from the ball valve, be absolutely certain that the ball valve is fully closed. Leakage from the coupling nut 4 threads or around the packing bushing 7 may indicate that the sensor is still under pressure. Leakage through a partially open valve could be hazardous. However, with the ball valve closed, some residual process fluid may leak from the coupling nut connector s pipe threads. 4. Loosen coupling nut 4 and remove the sensor tube and retracting sleeve 9 together with the sensor tube 2. Disassemble the sensor tube assembly as follows: 1. Unscrew the compression nut 8, loosen the grommet, and unscrew the cable grip nut 5. Slide these three items and the knurled nut 1 off the tube and cable. 2. If the stop ring 6 has not been loosened, unscrew the three set screws. Slide the stop ring off of the tube and cable. The sensor tube assembly can now be removed from the packing bushing and retracting sleeve by pullin it forward. FIGURE 2-1. Retractable Mechanism. 2-2
