4-4. Mounting kit for refillable ref.
electrodes
This mounting kit replaces the standard
electrode mouting set so that elctrodes of
Yokogawa with a long glass shaft can be fixed
in the fitting or subassembly (see fig. 4-3). This
mounting kit may be used as process pressure
up to 3 bar. Higher pressure ratings require
the standard mounting set for electrodes with
DIN dimensions or, alternately a salt bridge
(see §4-5). The refillable electrodes can be
connected to a KCI-reservoir via a silicone
tubing (see fig. 4-3). The pressure on the KCI-
solution and consequently, the liquid outlet
can be increased by mounting the reservoir
above the fitting or subassembly. This prevents
penetration of the process liquid into the
electrode.
Note: The pressure on the KCI-solution must
exceed the liquid pressure. Figure 4-3

4-5. Cleaning systems
4-5-1. General
The standardised design of the fittings and subassemblies makes it possible to mount
cleaning systems directly. The 4-hole types are especially designed for these applications.
Three different types of cleaning systems are available (see fig. 4-4):
- mechanical cleaning (electrically or mechanically driven)
- chemical cleaning
Detailed specifications of the cleaning systems are on seperate sheets
(see GS 12B6V1-E-E).
