    摘要: The invention relates to a temperature measuring module (TCM) having position compensation, wherein the temperature measuring module (TCM) is provided to be connected to a thermocouple (T
    A ) or a plurality of thermocouples (T
    A , T
    B , T
    C ,... T
    N ). A thermocouple has two metallic conductors (L1, L2), wherein the two metallic conductors have a different chemical composition, at least to some extent, wherein the two metallic conductors (L1, L2) are connected in an electrically conductive and a point-like manner at the measurement point (10), wherein an electric thermocouple voltage (U
    thermo ) is formed between the two conductors (L1, L2) at the reference point (R) as a function of the temperature difference (ΔT) between the first temperature (T
    1 ) and the second temperature (T
    2 ). The temperature measuring module (TCM) also has a temperature-dependent resistor (PT) via which the temperature (T1) of the reference point (R) can be registered as a resistance voltage (U
    abs ). The temperature measuring module (TCM) also has an evaluation circuit (A) which permits a first temperature value (T
    mess1 ) of the measurement point (M) to be determined by means of the electric resistance voltage (U
    abs ) and the thermocouple voltage (U
    thermo ). The temperature measuring module (TCM) also has a compensation means (K), which changes the first temperature value (T
    mess1­ )
    as a function of the installation position of the temperature measuring module (TCM), such that it is at least partly possible to compensate for thermal influences of the evaluation circuit (A) that act thermally on the reference point (R) and/or the measurement point (M) as a function of position.

    摘要: A transmitter (10) in a process control loop (12) measures temperature. A calibrator (60) includes a known calibration element (64) which is connected to the transmitter (10). Software in the transmitter (10) compares a measured value of the calibration element (64) with the actual value of the calibration element (64) and responsively calibrates the transmitter (10). The calibrator (60) includes a temperature calibration sensor (70) for coupling to a terminal block (14) of the transmitter (10). The temperature calibration sensor (70) provides an actual temperature input to the transmitter (10). The transmitter (10) measures actual temperature of the terminal block (14) and compares actual temperature with a temperature measured by an internal terminal block temperature sensor (34), and responsively calibrates the internal temperature sensor (34).

    摘要: Apparatus for making a transition from leads (12-26) of a temperature measuring thermocouple to extension wires (44-58) within a hermetically sealed cable sheath (60) of small diameter. The interior of the cable sheath (60) is shielded from electromagnetic radiation by an electrically conductive liner (62). A thermally conductive, electrically Insulating material (66) surrounds the intermediate junctions (28-42). The temperature of the intermediate junctions (28-42) is measured (64) providing a signal to compensate the voltage generated by the temperature measuring thermocouples due to the thermoelectric effect of the intermediate junctions (28-42).

    摘要: The present invention relates to a method for temperature drift compensation of a temperature measurement device using a thermocouple. According to the method for temperature drift compensation of the temperature measurement device using the thermocouple of the present invention, the temperature drift may be compensated for through reference junction compensation alone using a thermistor for reference junction compensation without providing a separate temperature measurement element. Thereby, precision of a measured temperature doesn't change despite change in temperature of the surroundings measured by the temperature measurement device, and the manufacturing cost may be effectively reduced.
