  • 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.

  • Patent number: 8920027
    Abstract: In a semiconductor device or test structure, appropriate heating elements, for instance in the form of resistive structures, are implemented so as to obtain superior area coverage, thereby enabling a precise evaluation of the thermal conditions within a complex semiconductor device. In particular, the device internal heating elements may allow the evaluation of hot spots and the response of a complex metallization system to specific temperature profiles, in particular at critical areas, such as edge regions in which mechanical stress forces are typically highest in contact regimes in which the package substrate and the metallization system are directly connected.

  • Publication number: 20140376594
    Abstract: A temperature sensing assembly for measuring the temperature of a surface of a structure includes a thermocouple device having a sheath containing a pair of conductors of dissimilar materials connected at a junction point to provide indications of temperature. The assembly further includes a docking device with a recess formed in a top surface to receive a portion of the sheath that is proximate the junction point. The bottom surface of the docking device is attached to the surface of the structure. The recess extends through the bottom surface of the docking device so that when the thermocouple device is positioned in the recess, the junction point is adjacent the surface of the tube. A heat shield can be attached to the docking device to shield the sheath proximate the junction point from direct and radiant heat sources.

  • Publication number: 20140376593
    Abstract: A cooled thermocouple arrangement (1) including a thermocouple (2) comprising two wires (3,4) joined at a first sensing end (5) to define a hot thermocouple function. At least a portion of the wires (3,4) are in thermal communication with a cooling arrangement, and the cooling arrangement has an inlet (14) for coolant and an outlet (15) for coolant. The thermocouple probe arrangement (1) includes a first inlet temperature sensor (21) for determining the temperature of the coolant as it enters the cooling arrangement, and a flow rate sensor (20) for determining the flow rate of coolant passing through the cooling arrangement. The thermocouple probe arrangement (1) includes connectors for connecting the outputs from the thermocouple (2), first inlet temperature sensor (21) and the flow rate sensor (20) to a correction data processor (23) whereby the data processor can correct the temperature sensed by the thermocouple to take account of the effect of the cooling arrangement.

  • Patent number: 8899828
    Abstract: A heat sensor has the ability to correct for errors introduced during temperature changes of the hot junction of the thermopile for the heat sensor. For example, the effect of temperature changes at the hot junction of the heat sensor relative to the cold junction is mathematically modeled such that the effect on the temperature determination can be corrected given certain information relating to the thermopile, its electrical output, and the temperature history and current temperature of the cold junction. By accounting for these factors, a processing device can modify the temperature determination output for the heat sensor while correcting for error introduced by temperature changes at the hot junction as determined by the mathematical model.
