Embodiment Construction

[0050] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0051] refer to figure 1 , shows a heater in accordance with the teachings of the present disclosure and is generally indicated by reference numeral 20 . This form of heater 20 is a cartridge heater, however, it should be understood that the teachings of the present disclosure may be applied to other types of heaters described in more detail below while remaining within the scope of the present disclosure. As shown, the heater 20 includes a resistive heating element 22 having two ends 24 and 26, and the resistive heating element 22 is in the form of a wire, such as a nichrome material. The resistive heating element 22 is wrapped or disposed around a non-conductive portion (or core in this form) 28 . The core 2...

Abstract

The present disclosure is directed toward a heater that includes a resistive heating element, a first power pin, and a second power pin. The first power pin forms a first junction with a first end ofthe resistive heating element, and the second power pin forms a second junction with the second end of the resistive heating element. The second power pin includes a first lead wire and a second leadwire. The first lead wire forms the second junction with the second end of the resistive heating element and defines a first conductive material. The second lead wire forms a primary sensing junctionwith the first lead wire at a first reference area, and defines a second conductive material different from the first conductive material to measure a temperature at the first reference area based ona voltage change created by the primary sensing junction.

Description

technical field [0001] The present disclosure relates to resistive heaters and temperature sensing devices, such as thermocouples. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Resistive heaters are used in a variety of applications to provide heat to a target and / or environment. One type of resistive heater known in the art is a cartridge heater, which typically consists of a resistive wire heating element wrapped around a ceramic core. A typical ceramic core defines two longitudinal holes in which power / terminal pins are disposed. The first end of the resistance wire is electrically connected to one power pin, and the other end of the resistance wire is electrically connected to the other power pin. The assembly is then inserted into a larger diameter tubular metal sheath having an open end and a closed end or two open ends, thereby forming a...
