General information
2.3.1.1 Rating plate for the filtration probe sc
You will find the rating plate at the top end of the supply cable. On
the rating plate you will find
• The model number and the serial number,
• Information on the voltage and frequency for the electrical
connection and
• Information on the brief peak power consumption.
2.3.2 Principle of operation
The filtration probe sc draws in liquid through a filter system and
then pumps this sample flow to an analysis instrument connected in
series. After the analysis of the sample, the analysis instrument
pumps the sample (possibly mixed with chemicals) back to the tank
sampled or to a drain.
A cleaning device ensures the filter modules remain porous. The
filtration probe sc has a compressed air tube that terminates
underneath the filter modules. When compressed air flows out of
the air openings underneath the filter modules, the rising air
bubbles remove soiling from the filter modules. In this way the filter
modules remain porous and manual cleaning is largely
unnecessary.
