Abstract: 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.

Abstract: According to one embodiment, an apparatus is prevented from being stopped by a breakdown of one or more of multiple temperature detector used to detect an abnormality of a resonance frequency. The apparatus includes: a circuit that adjusts power from a power supply to power of a desired voltage; an inverter that converts the power output by the circuit into alternate-current power; a resonance circuit having an inductance and a capacitance; a transformer that converts the alternate-current power; a rectifier that converts the alternate-current into direct-current power; temperature detector that detects temperatures of the resonance circuit; and a controller that detects an abnormality of a resonance frequency in response to that the temperatures are equal to or higher than a predetermined temperature threshold, and, in response to that the temperature detector of the resonance circuit is abnormal, executes control for handling the abnormality of the temperature detector.

Abstract: Provided in this disclosure are systems and methods for determining a confidence level of a sensor measurement of a sensor. A system may include a sensor array, which includes a plurality of sensors configured to detect a physical phenomenon. Each sensor of the sensor array may generate an output signal that includes measurement datum related to the detected physical phenomenon, which may be received by a controller of the system. Controller may compare the measurement datum from a selected sensor to other sensors of the sensor array to determine the confidence level of the selected sensor.

Abstract: A method for the measurement of temperature in high temperature and high pressure processes includes the steps of providing at least a first material compound and at least a second material compound. The at least first and second compounds are mixed to form a material sample. The material sample is loaded into a device and the device and material sample are subjected to a high pressure of up to about 10 GPa and a high temperature of up to about 1700° C. to form the material sample into a solid crystalline solution. The material sample is recovered for analysis and the composition of the crystalline solid solution is measured to determine the temperature.

Abstract: The aim of the invention is to provide a commercially usable and inexpensive device and method with which a sorption enthalpy can be measured in a simple manner. This is achieved by a device for calorimetrically measuring sorption processes, comprising a sorption cell for receiving a sample, the sorption cell having a volume for filling with a sorption gas, and comprising a reference cell likewise for filing with the sorption gas. A measurement gas volume is arranged around the sorption cell for receiving a reference gas, and the reference cell is surrounded by a reference gas volume, which is likewise provided for receiving the reference gas. A gas connection is provided between the sorption cell and the reference cell in order to conduct sorption gas into the sorption cell and the reference cell such that a sorption reaction occurs with the sample in the sorption cell. Furthermore, a device is provided for measuring pressure differences between the measurement gas volume and the reference gas volume in order to carry out a calorimetric measurement of the sorption process on the sample in the sorption cell on the basis of a volume change of the reference gas in the measurement gas volume.
