  • Multipoint thermocouple assembly
    Patent number: 5232517
    Abstract: An assembly for permitting temperature measurements at a large number of locations within a vessel, which assembly has a spreader-reducer for compacting a significantly large number of thermocouple cables into a relatively small volume so as to permit passage through one or more vessel nozzles. The thermocouple cables each has a heat expansion portion as well as a seat, thereby permitting a series of horizontal arrays of thermocouple junctions positioned at different depths within the vessel.

  • Heat detection system
    Patent number: 4625200
    Abstract: A heat detection system comprised of a length of thermocouple cable positioned proximate to the area to be controlled, said cable having the capacity to detect hot spots or areas, said cable being electrically connected to a plurality of transmitters for generating signals as a function of excessive temperature and/or line break, said transmitters, in turn, being electrically connected to one or more of a plurality of alarms adapted to indicate said excessive temperature and/or line break.
