  • Sensors for sensing a plurality of parameters
    Patent number: 4099164
    Abstract: Sensors, or transducers, which utilize elongated magnetically saturable tubes with sense lines that run through the tubes for simultaneous sensing of a plurality of parameters are disclosed. One version involves a single sensing element which has a first pair of diametrically disposed magnetic poles responsive to one condition that is positioned adjacent to one end of the tube and a second pair of diametrically disposed magnets responsive to another condition that is positioned adjacent to the other end of the tube. Another version involves two elements which have temperature vs. inductance characteristics which intersect, and a pair of diametrically disposed magnets responsive to another condition positioned adjacent the two elements.
    Type: Grant
    Filed: February 28, 1977
    Date of Patent: July 4, 1978
    Assignee: Illinois Tool Works Inc.
    Inventors: Edward F. Sidor, Charles C. Camillo, Glenn W. Bowen
