RESISTANCE CALIBRATION AND MONITORING OF THERMAL SYSTEMS
A method of calibrating temperature of a resistive element having a material with a Curie temperature includes generating a standard resistance-temperature (R-T) curve for the resistive element in isothermal conditions to identify values of the R-T curve and an inflection point at the Curie temperature, generating operational R-T curves for the resistive element over an operational time period, comparing the standard R-T curve to the operational R-T curves, and adjusting the operational curves to the standard R-T curve at the Curie temperature to calibrate temperature of the resistive element.

TEMPERATURE SENSOR
The temperature sensor includes a temperature sensing element, a pair of element electrode wires, and a pair of terminals. An overlapping wire portion of each of the element electrode wires is connected to the terminal in such a manner as to overlap the terminal in an overlapping direction. A fillet portion is disposed on a side surface of the overlapping wire portion. The fillet portion has a pair of fillet pieces formed in such a manner as to crawl up from a specific main surface that is a main surface at the overlapping wire portion side in the terminal. In a cross section of the temperature sensor orthogonal to a sensor axis direction and passing through the fillet portion, the maximum length in a width direction of the fillet portion is defined as a fillet maximum width A, and a length in a width direction between a pair of boundary portions between the pair of fillet pieces and the specific main surface is defined as a boundary width B. The temperature sensor has, at least partly in the sensor axis direction, a specific cross section satisfying B≤A, as a cross section of the temperature sensor orthogonal to the sensor axis direction and passing through the fillet portion.

A device having a first terminal region and a second terminal region. The first terminal region includes fine-tune (FT) metal stripes that are separated from each other by a first distance along the longitudinal direction. The second terminal region is spaced apart from the first terminal region by at least an inter-terminal distance. The second terminal region includes coarse-tune (CT) metal stripes that are separated from each other by a second distance along the longitudinal direction. The second distance is greater than the first distance, and the inter-terminal distance greater than the second distance. Each of the FT metal stripes may be selected as a first access location, and each of the CT metal stripes may be selected as a second access location. A pair of selected first and second access locations access a sheet resistance defined by a distance therebetween.
