Conductive level switch ELECTRA-SL

for liquidsstainless steelpolypropylene

Conductive probes SL series constitute, in combination with the electronic control units VNR21.22, a valid solution for controlling the level of liquid with minimum value of conductivity of 1S. The probes are available in a wide variety of materials and process connections and their construction has been appropriately designed to ensure high operational reliability in difficult conditions, such as those found on industrial plants. • Up to 4 electrodes. • Coated electrodes. • Hermetic construction, epoxy resin sealed. • Electrical output via DIN 43650 plug. INSTALLATION AND MAINTENANCE Installation: As necessary and depending on the level under control, the electrodes must be shortened, according to the following precautions: 1) The ground electrode must always be the longest and be always immersed in the liquid to be controlled. 2) Once you have shortened the electrodes, remove the coating on the terminal part for about 1 cm. exposing the metal part. Maintenance: The only recommendation to be observed is: Periodically check the condition of the electrodes and their coating and possibly clean the same with non-aggressive liquids.
