Patent ID: 8305186

Claim:
A resistive temperature detector assembly comprising: a. a primary resistive element for detecting temperature, said primary resistive element characterized by a temperature coefficient of resistance TCR 1 ; b. a first subassembly comprising a first subassembly resistive material characterized by a temperature coefficient of resistance TCR 2 , said first subassembly resistive material configured and/or adapted so as to permit selective passage of current through at least a portion thereof in furtherance of calibration of said primary resistive element; and, c. a second subassembly comprising a second subassembly resistive material characterized by a temperature coefficient of resistance TCR 3 , a value of one of either of said temperature coefficient of resistance TCR 2 or said temperature coefficient of resistance TCR 3 being greater than a value of said temperature coefficient of resistance TCR 1 , a value of another of said either of said temperature coefficient of resistance TCR 2 or said temperature coefficient of resistance TCR 3 being less than a value of said temperature coefficient of resistance TCR 1 , said first and said second subassemblies, and said primary resistive element, operatively united for receipt of current therethrough.
