Claim Text:
1. A control circuit for a probe, the control circuit comprising: at least one low temperature coefficient of resistance component placed in at least a first section of a probe, wherein the at least one low temperature coefficient of resistance component has a low positive temperature resistance coefficient; at least one high temperature coefficient of resistance component placed in at least a second section of the probe and connected in series with the at least one low temperature coefficient of resistance component, wherein the at least one high temperature coefficient of resistance component has a high positive temperature resistance coefficient, and wherein the at least one high temperature coefficient of resistance component responds to temperature differently than the at least one low temperature coefficient of resistance component; and at least one shunt component connected in parallel with the at least one high temperature coefficient of resistance component, wherein when the temperature of the at least one high temperature coefficient of resistance component exceeds a set temperature point, the at least one shunt component is activated to reduce the current flowing through the at least one high temperature coefficient of resistance component.
