Abstract:
A thermocouple-to-extension wire ambient temperature error correction device comprising:an isothermal mass, wherein said isothermal mass comprises a material that prevents electrical conductivity;a plurality of terminals, wherein said terminals are of a length longer than the thickness of said isothermal mass, are positioned radially parallel around the periphery of said isothermal mass, one end of said terminals extending outward on exterior portion of said isothermal mass, an opposite end of said terminals extending into an internal cavity of said isothermal mass, and having a means for connection of two conductors each;a thermistor, wherein said thermistor is centrally positioned within said isothermal mass, comprising self heating characteristics for generation of heat flow to said terminals;a thermal conducting means, wherein said thermal conducting means encompasses said thermistor within central cavity of said isothermal mass;an insulation means, wherein said insulation means surrounds said isothermal mass, for constraint of heat flow from said terminals to an ambient area;a casing wherein said casing houses said isothermal mass, said plurality of terminals, said thermistor, said thermal conducting means and said insulation means.
