1 Installation & Calibration EquipmentSensor & Instrument Mounting, Accessories, Systems and MoreVisualize > Analyze > OptimizeINSTALLATION & Calibration EQUIPMENTE merson Process Management offers a variety ofRosemount Analytical accessories to fit manyrequirements. This brochure includes mounting tees, ballvalve kits, and other configurations used for mountingconductivity, pH, ORP and amperometric (dissolvedoxygen, chlorine, and ozone) sensors and note that each mounting accessory is only valid forthe stated sensor (s). Also included is information oninstrument mounting, cables, junction boxes and variouschemicals.

2 The accessories in this brochure can be used ina wide variety of applications commonly found in thefollowing industries:> Chemical> Food and Beverage> Water and Wastewater Treatment> Power> Water Treatment> Utilities> Pulp and Paper> Metals and Mining> Hydrocarbon Processing> Textile> PharmaceuticalMounting Recommendations for Sensors includes best practices for in-line and tank sensor Mounting including tees, low flow cells, handrail mounting, floating balls, jet spray cleaner, mounting adapters, and process Assemblies including ball valve kits, retraction assemblies for higher pressures, and a rotary retraction unit.

3 19-27 Instrument Mounting with mounting brackets for wall, pipe, or panel Accessories includes best practices for cable lengths. Also includes junction boxes, extension cables, VP connector cables and cable Accessories with pH buffer solutions and conductivity standard solutionsAlso included is a conductivity validation unit, a pH benchtop Calibration unit,a pH simulator, and VP plug simulator for pH and Accessories including rotameters and a constant head flow for Sensors and Parts and Assemblies including examples of customer requested panels with sensors,flow cells, instruments, and sample cooling system mounted for easy for Sensors.

4 Instruments and Chemicals including Certificate of Calibration , Electronic Calibration , Loop Calibration , & Material Certificates..46 Index for quick and easy searching for parts by number or OF CONTENTS3 CHOOSING THE RIGHT MOUNTING SOLUTIONU nderstanding sensor processconnections: Rosemount Analytical sensors are offered with a widevariety of threaded process connections. The sensor shown above is a 3900 pH sensor . All sensorsuse similar terminology for process connection that not all sensors are offered with front and backend threads. Below are examples of sensors using othertypes of sensor -to-process connection sensors shown in Figures 2 and 3 are muchdifferent than the sensor shown in Figure 1.

5 Figure 2 isa 228 Toroidal sensor with 3/4" MNPT threads and isalso available with 5/8" UNC threads. Figure 3 shows anon-threaded 3300HT pH sensor which is used with aprocess connector (sold separately) to allow variableinsertion depths for the sensor and easy sensorremoval without twisting the cable. Ordering InformationAll sensors used with the accessories mentioned in thiscatalog must be purchased separately. Also, please notethat additional accessory items must be purchasedalong with the stated mounting accessories in order forthe complete mounting to be accomplished.

6 Pleaseconsult your local representative for more informationabout sensors or consult the factory at 1-800-854-8257(in the ) or 1-949-757-8500 (outside of the ).You can also visit us at END PROCESS THREADS, CLOSESTTO CABLE OR VP CONNECTORPROCESS END (FRONT END)THREADS, CLOSEST TOSENSING/MEASURING ENDOF THE SENSORF igure 1. The 3900 general purpose pH sensor is offered with 1 inch MNPT threads in two locations: one on the process end and one on the cable alsohas a 3/4 MNPT process end 2. The 228 Toroidal Conductivity sensor is offeredwith back end process threads 3.

7 The 3300HT sensor is offered without processthreads. A compression fit, process connector is used onthe sensor body and gives the user flexibility for sensors (a longer version of what is shownabove) are also offered without process threads. This is sothe sensor can be mounted through a ball CONNECTOR SHOWN; SENSORS AREALSO AVAILABLE WITH INTEGRAL CABLEP rocess connector required forconnection of sensor to mounted in tees and flow cells:> To prevent leakage, wrap the sensor threads with pipetape before inserting into its mounting.> Do not over tighten the sensor when installing.

8 Handtighten the sensor , and then tighten with a wrench.> The electrodes must be completely submerged in theprocess liquid to measure properly 4 MOUNTING RECOMMENDATIONS FOR SENSORSF igure 4. pH sensor recommended mounting orienta-tion. pH sensors should be mounted at least 10 from thehorizontal to ensure correct measurement. Sensors canalso be mounted 5. Chlorine, dissolved oxygen, and ozone sensorrecommended mounting orientation. Chlorine, dissolvedoxygen, ozone sensors should be mounted vertically orwithin 45 of the horizontal position. Also, these sensorshave recommended flow rates that should be instruction manual for more information on recom-mended flow 6.

9 Conductivity (contacting) sensors should have atleast 1/4 in. ( cm) clearance between electrodes andpiping (as shown in both illustrations above). The recom-mended sensor orientation is either horizontal or no more than30 below horizontal. It is best that the inlet flow is facing thesensor to ensure full pipe and minimal air bubbles.> Air bubbles accumulating on sensors will cause erro-neous or erratic readings. > To control air bubble formation, apply a small amountof back pressure to the flow cell or pipe.> All sensor cables should be run through a conduit toprotect the back end from moisture intrusion.

10 5 MOUNTING RECOMMENDATIONS FOR SENSORSS ensors submerged in tanks, ponds, or basins> To prevent leakage, wrap the sensor threads with pipetape before inserting into its mounting part.> Do not over tighten the sensor when installing. Handtighten the sensor , and then tighten one or two (1 2)turns with a wrench.> The electrodes must be completely submerged in theprocess liquid to measure properly.> All sensor cables should be run through a pipe conduit;do not use the sensors cable to dangle the sensor intothe tank, pond, or InstallationDo not install sensor by hanging it directly into InstallationAlways install sensor using pipe 9.
