PREFACE 1.1 Introduction This instruction manual provides information for the installation and use of the FU20F SENCOM™ sensor. This digital sensor shows how Yokogawa applies the motto “Simply the Best” to sensor technology. Setup of the sensor is very easy because all sensor specific characteristics, such as calibration data, are stored in the sensor. The FU20F SENCOM™ sensor holds four separate measuring elements in one unbreakable and chemical resistant PPS 40GF (RytonTM) wide body: • pH glass electrode. • Long life saturated Ag/AgCl reference system with double junction, combined with ion-trap to prolong the lifetime of the reference probe even in chemically unfavorable environments. • Integral Pt1000 element for accurate temperature measurements. • Solid Platinum ORP/LE electrode for accurate simultaneous pH and ORP measurements. Other valuable features of the sensor: • PTFE reference diaphragm to prevent fouling. • Polymerized electrolyte to extend the sensor lifetime. • Available in two versions, a robust dome shape model for applications with a limited amount of solids, and a flat surface model for applications in which solids are a considerable component, such as in the pulp and paper industry. •Versatile in-line or off-line installation. Optional quick-removal adapters in both stainless steel and titanium are available to make calibration and maintenance even easier. The FU20F is provided with a multipole M9 male connector for connection to the Yokogawa FLXA analyzer using the WU11 interconnection cable for SENCOM™ sensor. This cable, available in 4 fixed lengths, is specified for reliable transfer of digital signals and especially designed to be IM 12B6J3-04E-E installed in a heavy industrial environment. The double shielded cable will protect both the sensor and the analyzer for interference from high voltages and currents which are present on other cables. 1.2 Unpacking and Checking Upon delivery, unpack the sensor carefully and inspect it to ensure that it is not damaged during shipment. If damage is found, retain the original packing material and immediately notify the carrier and the relevant local Yokogawa Sales office. Make sure the Model Code and Serial Number on the sensor are the same as on the packing list. Also check if option(s) that were ordered, are included and correct. 1.3 Warranty and Service Yokogawa products are guaranteed free from defects in workmanship and materials under normal use and service for a period of (typically) 12 months from the date of shipment from the manufacturer. Individual Sales organizations can deviate from the typical warranty period, and the conditions of sale relating to the original purchase order should be consulted. Damage caused by wear and tear, inadequate maintenance, corrosion, or by the effects of chemical processes is excluded from this warranty coverage. In the event of a warranty claim, the defective goods should be sent (freight paid) to the Service Department of the relevant Yokogawa Sales office for repair or replacement (at Yokogawa’s discretion). The following information must be included in the letter accompanying the returned goods: • Model Code and Serial Number. • Original Purchase Order and Date. • Length of time in service and description of the process. • Description of the fault and circumstances of the failure. • Process/environmental conditions that may be related to the failure of the sensor. • Statement as to whether warranty or nonwarranty service is requested. 7 •C  omplete shipping and billing instructions for return of material, plus the name and phone number of a contact person that can be reached for further information. • Clean Statement Returned goods that have been in contact with process fluids must be decontaminated and disinfected prior to shipment. Goods should carry a certificate to this effect, for the health and safety of our employees. Material Safety Data sheets must be included for all components of the process to which the sensor(options) have been exposed. 1.4 Serial Number definition The Serial Number is defined by nine (9) alphanumeric characters: X1X2 Production Location X3X4 Year/Month code X5X6X7X8X9 Tracking number Example: N3P600028 Method used for year/month numbering Table 1: Production Year code Table 2: Production Month code Year Year code 2014 P 2015 R 2016 S 2017 T 2018 U 2019 V 2020 W 2021 X 2022 Y 2023 Z 2024 1 2025 2 Month January February March April May June July August September October November December Year Year code 2026 3 2027 4 2028 5 2029 6 2030 7 2031 8 2032 9 2033 A 2034 B 2035 C 2036 D 2037 E Month code 1 2 3 4 5 6 7 8 9 A B C IM 12B6J3-04E-E 8 2.

INSTALLATION OF FU20F For optimum measurement results, the FU20F should be installed in a location that offers an acceptable representation of the process composition and DOES NOT exceed the specifications of the sensor. The FU20F is designed with 3/4” NPT threaded connections on both ends of the sensor to allow installation in a wide variety of applications. 3.1 Typical installation The FU20F sensor is designed for versatile in-line, immersion or off-line installation. For best results the FU20F should be mounted with the process flow coming towards the sensor, and positioned at least 15° above the horizontal plane to eliminate air bubbles in the pH glass bulb (see Figure 4). 3.2 Preparing the sensor for use Remove the sensor from its shipping box and slide of the so-called ‘wet pocket’, the tube filled with solution to prevent drying out of the measuring elements during shipment or storage. Although in the sensor all factory calibration data is stored, it is recommended to calibrate the sensor before first use. A general calibration procedure is described in Section 6 of this Instruction Manual. 3.3 Mounting the sensor The simplest mounting is to use one of the 3/4” NPT threaded connection of the sensor. Apply Teflon tape to the appropriate threaded end, then install the sensor in the process (see Figure 5).

GENERAL CALIBRATION & MAINTENANCE PROCEDURE Calibration of the FU20F pH/ORP SENCOM™ sensor can be done on site with the FLXA analyzer connected, or in the laboratory with another FLXA analyzer or with the dedicated Yokogawa SENCOM™ PC software, model SPS24. When using another FLXA analyzer, it has to be set correctly for each calibration. Refer to the FLXA analyzer Instruction Manual for details. After calibration all data will be stored in the sensor itself. If the sensor is reconnected to the FLXA analyzer in the field, the calibration data of the sensor is automatically set into the analyzer. 6.1 Calibration for pH measurement To calibrate the FU20F pH/ORP SENCOM™ sensor, two buffer solutions with known pH values are required. It is recommended that one buffer solution has a value near to pH 7.00. Depending on the process value to be measured, the second buffer solution should be either acidic (below pH 7.00) or alkaline (above pH 7.00). Normally the IEC buffers (pH 4.01, 6.87 and 9.18) are used. The following is a very general 2-point calibration procedure: 1. Clean the sensor using a 5% solution of HCl; 2. Rinse sensor thoroughly with demineralized water; 3. Immerse the sensor in the first buffer (pH 6.87 is recommended) and execute calibration as described in the instruction manual of the analyzer or SPS24 PC software; 4. Rinse sensor thoroughly with demineralized water; 5. Immerse the sensor in the second buffer (pH 4.01 or 9.18 is recommended) and execute calibration as described in the instruction manual of the analyzer or SPS24 PC software; 6. Rinse sensor thoroughly with demineralized water. During calibration, the temperature compensation should be active. The FLXA analyzer automatically compensates for the sensitivity change of the pH sensor at different temperatures. After calibration, replace or re-install the sensor into the process. IM 12B6J3-04E-E 19 6.2 Calibration for ORP and rH measurement For calibration of ORP and rH, the procedure for MANUAL CALIBRATION can be used as described in the Instruction Manual of the FLXA analyzer. The rH value is a function of the reference system and the pH value of the buffer solution. The FU20F sensor has a reference system of saturated Silver/Silver Chloride (Ag/AgCl). The commonly used standards for ORP and rH calibration are made from Chinhydron (Quinhydrone) powder dissolved in pH buffer solutions (1 g / 200 ml). In Table 4 the measurement values are given as function of the used pH buffer solution with Chinhydron powder. The accuracy of the standards is approximately ± 10 mV.

Depending on the process, different cleaning solutions may be required. A  void cleaning the complete sensor with solution. Some cleaning solutions will damage the modelcode sticker and connector which are placed on the electronic housing on top of the sensor. Only clean the measuring elements at the bottom side of the sensor. In most cases cleaning with water, iso-propanol or methanol is sufficient. In other cases the measuring elements of the sensor have to be cleaned with specific solutions. Examples: 1. Deposits of limes, hydroxides or carbonates can be removed by immersing the bottom part of the sensor in a solution containing dilute hydrochloric acid (5% is recommended). Afterwards rinse the sensor with water. 2. Deposits of oil and fat can be removed with hot water with a detergent. When the results are unsatisfactory, a mild (carbonate based) abrasive can be used. 3. Protein deposits should be removed with a protein enzymatic solution, for instance a solution containing 8.5 mL concentrated hydrochloric acid and 10 grams of pepsin in 1 liter of water. Note: Avoid cleaning with non-polar solvent like tri-chloro ethylene, toluene or hexane. The non-polar solvents will break up the gel-layer on the pH glass bulb and requires that the sensor has to be soaked in water for at least 12 hours before it will function again. The Teflon diaphragm of the sensor can be regenerated by putting it in hot (± 70°C, 158°F) 3 molar Potassium Chlorine (KCl) solution and letting it cool down to room temperature. This procedure clears the diaphragm and will soak the diaphragm with conductive KCl again. IM 12B6J3-04E-E 20 7.
