Wear Parts
The evaluation unit does not include any parts that are subject
to wear or components that require special maintenance.
The plastic caps of the measuring rods of the container probes
and the PEEK Microwave window of the flow cell may be subject
to abrasion over the course of time. A low to medium abrasive
influences the measurement only very little and can be compen-
sated for by a calibration. Therefore, check the wear parts in in-
tervals of about 2 years. In case of heavy wear, the plastic caps
of the measuring rods of the container probe and the PEEK Mi-
crowave window of the flow cells can be replaced.
The plastic caps of the measuring rods can be replaced on site.
For this purpose, please proceed as follows:
1
Unscrew the two plastic caps from the measuring rods and
remove the four sealing rings (see figure 5-1, yellow arrow).
2
Clean the four grooves of the sealing rings with a lint-free (if
necessary wet) cloth.
3
For each measuring rod, insert two new sealing rings into
the grooves.
4
Screw on the two new plastic caps.
