    Questions

    Question
    Why is the minimum specific gravity important on the float level switches?
    Answer
    If a medium has a lower s.g. than the rated minimum for a float, the float will sink through the media and the switch will not operate.

    Question
    The catalog page for the CFS2 level switches states, "Optional cables available include those with drinking water suitability." Which cable should I specify for use in a drinking water application?
    Answer
    Our cables that are compatible with drinking water must be purchased in quantities of 1000pcs. The cables we carry in stock that have a minimum order quantity of 1 pc are not drinking water approved.
