1. In an Electroconsolidation apparatus having a die cylinder, first and second hydraulically-actuated, conductive rams slidably received in opposite ends of the die cylinder;

  • first and second electrical leads in conductive contact with the first and second rams, respectively, the electrical leads being attached to a source of electrical power; and

    an electrically-conductive, pressure-transmitting medium disposed within the cylinder between the rams;

    the improvement comprising;

    an apparatus for measuring the temperature within the die including a transmitting transducer associated with one of the first and second rams;

    a receiving transducer associated with the other of the first and second rams, the transmitting transducer and the receiving transducer being spaced apart a distance within a predetermined range;

    a signal generator associated with the transmitting transducer for creating a tone that is transmitted from the transmitting transducer to the receiving transducer;

    whereby the temperature of the electrically-conductive, pressure-transmitting medium is calculated by measuring the time of flight of a tone created by the signal generator between the transmitting transducer and the receiving transducer.
