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.

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
- ultra sonic cleaning
Detailed specifications of the cleaning systems are on seperate sheets (see GS 12B6V1).
