摘要： 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.

摘要： 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.

摘要： 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.

摘要： A system and method for detecting an erratic state of a monitored sensor includes generating a variation value for a monitored signal generated by a monitored sensor and a variation value for an estimated signal estimated based on a predictive signal generated by predictive sensor, where the predictive signal is predictive of the monitored signal. The monitored signal can rapidly fluctuate based on system operating conditions. A dynamic threshold value is generated based on the estimated variation value, and the monitored signal is compared with the dynamic threshold value to determine if the monitored signal is in an erratic state. The detection method is sufficiently sensitive to distinguish between rapid fluctuation of the monitored sensor and an erratic state.

摘要： Disclosed is a temperature correction method for a thermal analysis apparatus which measures electric current, voltage, and electric resistance of a measurement sample while changing the temperature of the measurement sample set between a pair of electrodes. The paired electrodes are connected by a reference substance, and a weight is set on the reference substance. The temperature at the time when the reference substance is fused and the weight falls cutting the reference substance is measured actually as melting point by a temperature sensor. Based on a difference between the actually measured value and a literature value of the melting point of the reference substance, the temperature measured by the temperature sensor is corrected. It is thus possible to correct precisely the results measured by the thermal analysis apparatus which deals with electric current, voltage, electric resistance, dielectric constant, electric capacity, thermal electromotive force, thermally stimulated current, and the like, as targets to be measured.
