    Robustly made from 316 stainless steel and fitted as original equipment for over 30 years by all the major British and European boat builders, our senders still work on the simple principle of twin magnets in the float tripping a series of reed switches securely housed, and doubly insulated inside the stainless tube.

    Over the years senders have been improved with advances in reed switch technology, allowing us to fit far more switches inside the senders, giving the better resolution required by modern digital displays.

    The holding tank senders are surrounded by a removable 316 stainless steel cage to protect the float from the worst of the black water.  If necessary this is easily removable for cleaning.

    All of our holding tank senders work on the 240-30 ohms resistance range. Senders and gauges must have the same resistance range.

    There are also four sizes of holding tank senders available with a 0-10 volt output.
