1.1 Introduction
This Instruction Manual provides information for the installation and use of the FU24F 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 FU24F 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.
The Model FU24F offers a simple and cost effective solution for process
applications with fluctuating pressure and/
or temperature which normally limits the lifetime of a sensor.
By using the patented Bellow system a strong pressure compensation mechanism is created. This ensures immediate interior pressure equalization to the outside process pressure, making the sensor virtually insensitive to process pressure variations.
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 application in slurries, such as in the pulp and paper industry.
• Versatile in-line or off-line installation.
The FU24F is provided with a multipole M9 male connector for connection to the
Yokogawa FLXA analyzer using the WU11
interconnection cable for SENCOM™
sensors. This cable, available in 4 fixed
lengths, is specified for reliable transfer of digital signals and especially designed to be 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.
A slight overpressure caused by the bellow
tension prevents process fluid ingress and maintains a positive ion flow out of the sensor. This feature is of particular interest in pure water applications.

3. INSTALLATION OF FU24F
For optimum measurement results, the FU24F should be installed in a location that offers an acceptable representation of the process fluid composition and does not
exceed the specifications of the sensor. The
FU24F is designed with 1” NPT threads on either end of the body to allow installation in a wide variety of applications.
3.1 Typical installation
The FU24F sensor can be installed in-line, in a bypass loop or in an immersion assembly. For best results the FU24F should be mounted with the process fluid flowing towards the sensor. The sensor can also be mounted horizontally or any other angle.
3.2 Mounting the sensor
The FU24F can be mounted using the
threads on the body of the sensor. Apply
Teflon tape to the appropriate threaded end. Do not overtighten the sensor. When
using a (fork) wrench, the maximum
applicable torque is 100 Nm.
IM 12B6J8-01E-E
For mounting the sensor in a flow fitting (FF20-*22, FF20-*33) or subassembly (FS20-*22, FS20-*32), use spare part
K1521JA or K1521JB.
See Section 5 for instructions to wire the sensor to the instrument.
3.3 Preparing the sensor for use
Remove the sensor from its shipping box
and slide off the “wet pocket” (the flask including the rubber ring) This wet pocket is filled with a saline solution to prevent the sensor from drying out during storage.
Important: Inserting a sharp pointed device in the hole in the measuring end of the sensor, might damage the sensor and result in severely reduced life time!
Before mounting the sensor, it should be validated with buffer solutions and calibrated when necessary. The specific calibration procedure is described in the Instruction Manual of the pH transmitter, but a general procedure is also provided in section 6 of this manual.

6. GENERAL CALIBRATION & MAINTENANCE PROCEDURE
Calibration of the FU24F 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 read by the analyzer.
6.1 Calibration for pH measurement
To calibrate the FU24F 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, re-install the sensor into the process.
IM 12B6J8-01E-E
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 FU24F 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.

6.87 96 88 23.6
7.00 88 88 23.6
6.3 Maintenance of the FU24F sensor
A pH sensor requires routine maintenance to keep the measuring elements clean and
functioning. Depending on the process, different cleaning solutions may be required.
Avoid 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 solvents 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 Chloride (KCl) solution and letting it cool down to room temperature. This procedure clears the diaphragm and will soak the diaphragm with conductive KCl again.
