4-2. Mounting kit (order nr. K1500BY)
This mounting kit replaces the standard
electrode mounting set so that Yokogawa
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. Higher pressure
ratings require the standard mounting set
and consequently, electrodes with DIN-
dimensions.
Figure 4-2 shows the mounting.
Note:
The pressure on the KCI-solution must
always exceed the liquid pressure.
The refillable electrodes can be connected
to a KCI-reservoir via a silicone tubing
(see figure 4-2). The pressure on the
KCI-solution and consequently, the liquid
outlet of the electrode can be increased by
mounting the reservoir on top of the fitting.
This prevents penetration of the process
liquid into the electrode.
