1. 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.
•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.

3. 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.
The FU20F can also be mounted using one of the optional quick-removal adapters (/NSS, /NTI, /BSS or /BTI). For a detailed description of these adapters see Sections 4 and 7 of this Instruction Manual. 1 Apply Teflon tape to the threaded end of this adapter; 2 I nstall the adapter in the process connection. Tighten the adapter using a wrench on the adapter flats.

5. WIRING 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. The connections of this M9 male connector (see Section 2.7 for details), the WU11 interconnection cable and the FLXA terminal strip are given in Table 3.
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).
