  • Patent number: 9714874
    Abstract: By correcting temperature measurements above a surface (such as the ground) for the first-order filtering associated with the thermal inertia of a temperature sensor (such as a thermocouple) that performed the temperature measurements, the heat flux conveyed from the surface by air can be accurately determined without requiring a calibration procedure. Instead, a predefined calibration value may be used. This predefined calibration value may be a function of a size of the temperature sensor and/or a distance between the temperature sensor and the ground. Moreover, the predefined calibration value may have a fixed value for a given size of the temperature sensor. In addition, the measurement of the heat flux conveyed from the surface can be used to accurately determine the residual heat flux that vaporizes water from the surface without a calibration procedure.

  • Patent number: 8996327
    Abstract: An I/O circuit for measuring temperatures uses multiple cold-junction compensation sensors permanently affixed near the terminals of the terminal block in order to compensate significant temperature variation across the terminals of the I/O module (up to 3° C.) that can substantially affect the accuracy of thermocouple measurements. The use of these multiple sensors is enabled by a compensation system that corrects for the distance between the built-in sensors and the terminals, a multiplexer that accommodates the additional signal burden produced by the sensors, and a compensation system that allows low-cost sensors to be used and calibrated to as little as a single high accuracy sensor. In one embodiment, a third temperature sensor with relatively higher accuracy is used to compensate for lower accuracy of permanently affixed sensors.

However, the activity of fermentation disrupts the tendency of the brew to stratify. Accordingly, the brewing apparatus comprises at least two temperature sensors positioned to measure a temperature difference between the temperature at a first height of the brew and the temperature at a second height of the brew.

  • Patent number: 8517600
    Abstract: A system and method are disclosed wherein differential heat transfer resistances are used to effectively and efficiently detect the early onset of deposit accumulation in industrial fluid processes and fluid transport vehicles. According to one embodiment, a probe is provided in conjunction with a heat source, a water source and a probe. The probe is comprised of a heat transfer surface, a first part of which is covered only by a thin metal layer. The second or remaining portion of the heat transfer surface is covered by a heat flux sensor and a thin metal layer. The metal layers of both the first and second areas of the probe are connected, and water flows across the full heat transfer surface. Deposition forms on a portion of the heat transfer surface as a result of slow water flow and elevated water temperature. The temperatures of the heat source, water source, and heat flux are measured. The deposition rate as a rate of change of heat transfer resistance is measured.

  • Patent number: 8517602
    Abstract: A method of using a temperature sensor to determine the temperature of an object is described. The method comprises bringing the temperature sensor into thermal contact with the object to be measured. The temperature sensor is then used to acquire a plurality of temperature readings, the plurality of temperature readings being acquired prior to the temperature sensor reaching thermal equilibrium with the object. At least some of the plurality of temperature readings are then used to determine a pseudo-stable temperature at which the rate of change of temperature readings with time is less than a predetermined rate. The actual temperature of the object may then be predicted from the pseudo-stable temperature.

  • 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.
