  • Method for obtaining electrical signals correlated with the position of a mass of mercury in instruments and the like
    Patent number: 5224385
    Abstract: A method of obtaining electrical signals corresponding to the position of a mercury mass movable within a vessel, characterized by the fact that the position of the moving mass within the vessel is detected by means of at least one electromagnetic proximity sensor, specifically an induction proximity sensor, that is a sensor adapted to producing an electrical signal when approached by a metal object or when approaching the same.
    Type: Grant
    Filed: February 27, 1992
    Date of Patent: July 6, 1993
    Inventors: Pier-Luigi Floris, Yvonne O'Toole
