Patent ID: 7044638

Claim:
A multi-element thermocouple circuit comprising: a first thermocouple comprising first and second thermoelements meeting at a first temperature measuring junction and having respective first and second distal ends, said first and second thermoelements being formed of respective first and second materials; a second thermocouple comprising third and fourth thermoelements meeting at a second temperature measuring junction that is connected to said first distal end, said third and fourth thermoelements having respective third and fourth distal ends and being formed of respective third and fourth materials, neither of said third and fourth materials being the same as either said first or second material; and a fifth thermoelement having a fifth proximal end connected to said second distal end and a fifth distal end, the fifth thermoelement being formed of said fourth material; wherein: the fourth thermoelement is common to two voltage difference subcircuits.
