Level controller for conducting liquits
WLS-GEH230V
Electrodes of stainless steel rods, hanged from top into the medium, are ideally suited for this purpose. The reference electrode is in the middle of
the 4 diagonally arranged sensing electrodes which are placed in a span of approx. 1-5 cm. The spacing should be wide enough so that no drop
of liquid sticks back to the rods when the level falls down. These electrodes are practically maintenance free.
Cable probes are very simple to manufacture. For this purpose, multi-core silicon cable can be stripped at the end and joined to stainless steel balls
which act as weight and also contact surface. The individual weights are lowered in the container up to the desired switching point and then the
cable is tied up. For reference electrode, a bare stainless steel rope with weight can be used, which goes up to the bottom of the container. Cable
sensing elements are also very reliable and practically maintenance free.
For applications in condensate tubs and for low liquid levels, the sensing system can be constructed as a PCB which is mounted on the tank wall.
Such sensing elements should also be periodically cleaned if the medium is polluted.
Attention
Please avoid extreme mechanical and inappropriate exposure.
The device/product is not suitable for potential explosive areas and medical-technical applications.
