摘要： Various techniques for implementing resistive temperature sensors that rely on the resistors' temperature sensitivity to provide temperature sensing are disclosed. Temperature sensitive resistors may be implemented in a resistor stack in combination with a resistor stack of resistors that are relatively temperature indifferent. Various temperature sensor circuits implementing these temperature sensitive resistors are also disclosed. A temperature sensor circuit may implement the temperature sensitive resistors along with the resistors that are relatively stable with temperature to output a voltage signal that is indicative of the temperature sensed by the circuit. In some instances, the signal from the temperature sensitive resistors is increased through the use of a feedback resistor loop.

摘要： A fluorescence temperature measurement material, a preparation method therefore and use thereof are disclosed, which belong to the technical field of fluorescence temperature sensing. The fluorescence temperature measurement material has a chemical composition of Na1-xSrxTaO3:yPr3+, x=0.1-0.2 and y=0.4%-0.6%. The fluorescence temperature measurement material is prepared by a high-temperature solid-phase method and generates blue light at 492 nm (3P0→3H4) and red light at 610 nm (1D2→3H4) under the excitation of 290 nm ultraviolet light. The fluorescence intensity ratio (1D2→3H4/3P0→3H4) of two emission peaks has an exponential function relationship with temperature, so that the fluorescence temperature measurement material can calibrate temperature and has good temperature-sensitive performance.

摘要： Provided is a temperature calibration method that makes it possible to efficiently calibrate temperature in a short time and enhance temperature calibration accuracy. This temperature calibration method uses a temperature calibration device (10) comprising a temperature calibration block (2) having formed therein a placement part (25) for a reference temperature sensor (5) and a temperature sensor (T) to be calibrated. In this temperature calibration method, a temperature state in a gradual temperature variation transition process of the temperature calibration block (2) is taken to be a calibration temperature. The temperature calibration device (10) comprises: a vacuum-insulated container (1) comprising a vacuum region (Va) surrounding the temperature calibration block (2) and an accommodation part for accommodating the temperature calibration block (2); and a Peltier module (3) that is thermally coupled to the temperature calibration block (2).

摘要： A method, apparatus and computer program product are provided to reliably determine a temperature, such as in the time domain. In this regard, an apparatus includes a delay line having a temperature dependent measurement invertor configured to stretch a clock pulse that was generated by an oscillating circuit during circulation of the clock pulse through the delay line. The amount by which the clock pulse is stretched during a cycle about the delay line is dependent upon temperature. The apparatus also includes detection circuitry configured to detect an instance in which clock pulse has been stretched so as to equal or exceed a period of the clock pulse. The apparatus further includes processing circuitry configured to determine the temperature based at least in part upon a number of cycles completed to stretch the clock pulse so as to equal or exceed the period of the clock pulse.

摘要： The present disclosure belongs to the technical field of power electronic converters, and discloses a method and a system for predicting a junction temperature of a power semiconductor module in the full life cycle and a terminal. The method includes the steps: arranging an NTC thermistor network to monitor the temperature of each area inside the power module when the power module works; obtaining data for training the neural network by utilizing finite element simulation or experiments, and building a neural network model among the temperature of the NTC resistor network, a water flow rate, an aging factor and the junction temperature of the chip under working conditions. The present disclosure improves the junction temperature prediction accuracy of areas with relatively large errors comprehensively and realizes the high-precision junction temperature prediction under all working conditions.
