  • Liquid Level Float Switches and Tranducers

    Liquid Level Float Switch and Transducers

    LOFA offers liquid level floats and transducers that easily connect to your standard CP750 and EP250G7A panels to help regulate liquid depth in pumping applications. LOFA senders and switches offer the same precision and reliability you’ve come to expect in a LOFA product.

    Float Switches:
    Standard floats and float kits are normally open switches and are 40 feet in length. Normally closed options and various lengths are available upon request. LOFA float switches are available with or without mercury.

    Transducers:
    Standard transducer kits include 2 meters (approximately 6.56 feet) of dry cable and a pressure range of 10 PSI (23 foot fluid depth). Various pressure ranges are available upon request.
