Page 12: Installation
The mounting position of the sensors must be within the area as shown in figure 3.1. 3.2 Installation Before installing the immersion fitting, check that all parts and accessories were supplied by Yokogawa. Ensure that there is enough spare around to withdraw the fitting for calibration and maintenance. -
Page 13: Cables And Sensor Mounting
Before mounting a sensor and/or accessory Type COAX the cables must be passed through the TRIAX fitting. When mounting Yokogawa sensors Length in mm 1 mtr the electrode cables, model WU20(D), 2 mtr should be used (see figure 3.2).

3.3.2 3-Hole and 4-hole fitting Unscrew the protector complete with Protection electrode holder from the lower end of the hose fitting (see figure 3.3). Unscrew the cap of an electrode mounting set. Pass the electrode cable through this cap and after that through the fitting. Mount the other electrode cables in a Glue similar manner. -

4. Mounting of Accessoires 4.1 Mounting kit option /B (FP20-S13) Using this mounting kit a SR20-AC32 reference electrode of Yokogawa can be mounted in a fitting (see figure 4.1). Electrodes to be used* Order nr. Description SR20-AC32 Reference electrode * For specifications of the electrodes see seperate sheets. -

Protection Hose This mounting kit replaces the standard KCI-Reservoir K1500CJ/CK electrode mounting set so that Yokogawa K1500FU refillable electrodes with a long glass shaft can be mounted in a fitting. The mounting set may be used at process pressures up to 3 bar. -
Page 18: Cleaning Systems
The Yokogawa program includes two 4.3 Cleaning systems The standardised design of fittings makes it different types of cleaning systems possible to mount FC20 cleaning systems (see figure 4.3): directly. The 4-hole types are especially - brush cleaning designed for these applications. -

Page 20: Chemical Cleaning
4.3.3 Chemical cleaning The chemical cleaning system is based on periodically spraying of a cleanser on to the glass membrane of the electrode. The cleanser to be used, the cleaning frequency, etc. are highly dependent on the liquid to be measured. The cleaning period and frequency can be adjusted on a control unit. -
Page 21: Salt Bridge
4.4 Salt bridge This reference electrode/salt bridge combination allows the measurement of pH and ORP (Redox) potentials with normal electrodes in those cases when: A. excessive contamination of the flow diaphragm is expected. The flow of the reference liquid through the diaphragm is increased by pressurising the container. -

5. Maintenance and Inspection 5.1 Cleaning and fitting Usally no cleaning is necessary. 5.2 Inspection of the O-ring seal The O-ring seal used in the wetted parts of the fitting is made of silicone rubber which has superior resistance to corrosion and is suitable for use with most process liquids. Usually no periodically inspection is necessary. - Page 23 1-Hole PVC Note This fitting has no liquid earth connection 3-Hole PP and PVDF 4-Hole PP and PVDF 3-Hole SS 4-Hole SS IM12B06K02-01E-E IM12B06K02-01E-E_ed09.indd 23 07/03/16 09:51...
