What is the purpose of the ” S” conductivity sensor in K Series models?
The conductivity sensor is inserted in the oil chamber and detects any water infiltration in the chamber from the mechanical seal. If the electrical panel has a detection device just connect the terminal with the “S” symbol and a branch of the yellow/green earth wire. The conductivity detection device is used to activate an alarm circuit in the event water is detected in the oil. The alarm can be visual and/or audible. The alarm can be either visual or audible. For explosion proof motors the devices used must be intrinsically safe and compatible with the zone classification in which they are in use.
