ABSTRACT:
A fluid bilevel sensor containing a differential float and a magnetically actuatable switch generating an electrical signal upon the occurrence of one fluid level. A thermal time delay delays the application of the electrical signal to a load for a predetermined time. The magnetically actuatable switch removes the electrical signal upon the occurrence of a second fluid level. The thermal time delay delays the removal of the electrical signal from the load for a predetermined time.
