ABSTRACT:
For liquid-level sensing in a tank, the invention provides a tank-mounted first subassembly that is adapted for suspension of a vertical guide from the top of the tank, such that a guided float may coact with an elongate vertical ribbon, to angularly displace a magnetic element carried by the upper end of the ribbon. The tank-mounting of this first subassembly completes closure of the tank and its contents, and closure structure of this first subassembly assures containment of the ribbon and its magnetic element within the closed volume of the tank. A second subassembly of magnetically responsive electrical means is encapsulated by a housing which is detachably connectable to the closure structure of the first assembly, solely by access that is external to the closed tank. Electrical output of the second subassembly is flexibly available to remote indicating and/or monitoring circuitry which forms no part of the invention.
