  • Patent number: 8308349
    Abstract: A heat flux probe uses a thermoelectric module to heat a relatively large sensing surface while cooling a substantially smaller one that is connected to the thermoelectric module by an elongated thermal conductor. A temperature difference between either the two sensing surfaces or the heated sensing surface and the cooled end plate of the thermoelectric module is controlled to have a selected value. Then the temperature change along the elongated thermal conductor is used as a measure of heat flux. This approach reduces inaccuracies arising from the thermal characteristics of the thermoelectric module and allows for in situ compensation for drift errors.

  • Patent number: 8215833
    Abstract: When the driving wind and the cooling wind are generated, based on the phenomenon in which the temperature difference is generated between the front surface and the rear surface of the radiator (14), the temperature difference between the detection value of the rear temperature sensor (22) and the detection value of the front temperature sensor (21) is compared with the abnormality determination value so that it is determined whether the front temperature sensor (21) and the rear temperature sensor (22) are properly fixed on the radiator (14), whereby it is determined whether the abnormality (unauthorized alteration) exists. By setting the abnormality determination value according to the ambient temperature and the vehicle speed, corresponding to a variation in temperature difference between the front surface and the rear surface of the radiator (14), the abnormality determination value is varied to be set at a proper value.

  • Patent number: 8142071
    Abstract: Thermal transfer measurements are useful for measuring either a mass flow rate or the specific heat of a fluid. Thermoelectric devices are desirable for this because of their ability to simultaneously heat one portion of the sensor while cooling another. However, the internal thermal resistance of thermoelectric devices has limited the accuracy of thermoelectric thermal transfer sensors. This problem is solved by using separate temperature sensors to measure selected temperature differences established by the thermoelectric portion of a thermal transfer sensor.

    Abstract: A temperature sensor is described that includes a base, a first set of posts attached to the base having a first coefficient of thermal expansion, a second set of posts attached to the base and having a second coefficient of thermal expansion, and two substantially parallel conductive plates forming a capacitor. The first of the conductive plates is fixed to the first set of posts and the second of the conductive plates is fixed to the second set of posts. Temperature changes cause the first set of posts and the second set of posts to elongate at different rates, thereby changing a distance between the conductive plates and therefore the resulting capacitance. A system and method are also described for determining resonant frequency associated with the sensor which correlates to the temperature at the sensor when multiple sensors are networked across a system.

  • Patent number: 7682074
    Abstract: A method and apparatus for estimating the true temperature of connate fluid within a subterranean geological formation is provided herein. The method includes generating a flow of connate fluid, measuring the temperature of the flow over time until the measured temperature reaches a limiting value termed the stabilized temperature. Multiple events of temperature sampling events can be conducted at different flow rates of the connate fluid. The stabilized temperature values can then be ascendingly organized based on the value of their respective flow rates. The limiting value reached by the stabilized temperatures is taken to be substantially equal to the actual temperature of the connate fluid residing within the subterranean formation.

  • Patent number: 7651263
    Abstract: A method and apparatus for measuring the temperature of a gas in a mass flow controller is described. One embodiment derives gas-temperature information from a mass flow sensor of the mass flow controller without relying on a separate temperature sensor. This embodiment supplies a substantially constant electrical current to a thermal mass flow sensor of the mass flow controller, the thermal mass flow sensor being designed to measure a mass flow rate of the gas; measures an input voltage of the thermal mass flow sensor to obtain a present input voltage, the input voltage varying with a temperature differential between a pair of sensing elements of the thermal mass flow sensor; calculates an adjusted input voltage by accounting for a component of the present input voltage that is dependent on the mass flow rate of the gas; and calculates the temperature of the gas based on the adjusted input voltage.

  • Patent number: 7517140
    Abstract: Techniques for precision testing of thermal interface materials are described. An apparatus may include multiple anvils each having multiple sensors disposed along its axis. A thermal interface material may be disposed between the anvils. A control module may be communicatively coupled to said sensors and arranged to receive temperature readings from the multiple sensors to form a temperature gradient, determine a surface temperature for each anvil based on the temperature gradient, determine a heat flux through the thermal interface material based on the surface temperature, and determine a resistance value for the thermal interface material based on the heat flux. Other embodiments are described and claimed.

  • Publication number: 20080253430
    Abstract: Method for measuring the local temperature in an industrial furnace (1) equipped with a burner (3), where at least two temperature sensors (21, 22) are arranged at different locations in the furnace (1). A virtual temperature measuring point is created by the association of each temperature sensor (21, 22) with a certain weight factor, in that the measurement values from each temperature sensor (21, 22) are weighted together using these weight factors in order to thus achieve a virtual measurement value, in that the weight factors at every given point in time are individually controlled based upon the momentarily emitted power of the burner (3), and in that the virtual measurement value in turn constitutes control parameter for the control of the emitted power of the burner (3).

  • Patent number: 7377687
    Abstract: A fluid temperature measurement probe, particularly for total temperature measurements in high temperature unsteady gas flows, such as in gas turbine engines. A pair of thin film resistance thermometers are deposited on the probe to sense its surface temperature at respective locations and the structure of the probe is configured such that the regions into which heat diffuses from the respective locations have different thermal products. In this way the thin film elements experience different heat transfer rates when exposed to the same fluid temperature. In one embodiment this is achieved by applying one of the elements to the surface of a solid rod of glass or ceramic and the other element to a portion which has been machined to leave an air pocket under a thin cylindrical wall of the rod material. In use the probe is exposed only temporarily to the high temperature fluid and withdrawn again before reaching its softening temperature.
