  • Cold junction thermocouple compensator
    Patent number: 4133700
    Abstract: 0.degree.COLD JUNCTION COMPENSATOR PROVIDES THE ELECTRICAL EQUIVALENT OF AN ICE-BATH REFERENCE THERMOCOUPLE, AT A SELECTED TEMPERATURE, FOR EXAMPLE O.degree. C. Input connectors, for engagement with conventional thermocouple units, form thermocouple junctions with conductors connected to a battery-operated Wheatstone bridge circuit adapted to supply an equal and opposite voltage output compensating for variations in the thermocouple junction output at different ambient temperatures. The compensator may be included in a module having input sockets or input plugs to coact with plugs or sockets of conventional thermocouple units. The compensator and battery may be encapsulated, or an accessible switch may be included in the battery circuit.
