Abstract
Current industrial and research applications that utilize resistance heating and temperature measurement require separate power and temperature connections, typically two for each. Such applications require separate assemblies and control. We describe herein a combined unit utilizing a thermocouple wire as one of its two leads. The resulting device requires only two connections and one control. An alternating cycle can be used to apply heating power, and temperature measurements are made during the power off portion of the cycle.
Claims8
A resistance heating device comprising an integrated temperature measuring device, wherein said heating device includes a thermocouple wire as a lead.
A method for providing both resistance heating and temperature measurement capabilities within a single integrated device, comprising applying an alternating cycle to said device, wherein temperature is measured during the portion of said alternating cycle when power is off, and heat is applied during the portion of said alternating cycle when power is on.
