摘要： A temperature detector for an exhaust gas sensor comprises: an exhaust gas sensor 2 for detecting a concentration of oxygen contained in exhaust gas discharged from an internal combustion engine; a temperature sensor 6 for measuring an environmental temperature which is substantially the same as the exhaust gas sensor 2; a resistance measuring means 12 for measuring an internal resistance value of the exhaust gas sensor 2; a timer means 10 for measuring an operation stop time of the internal combustion engine; and a control means 8 for detecting the internal resistance value of the exhaust gas sensor 2 and the environmental temperature at each operation starting point when a period of operation stop conducted by the timer means 10 is longer than a predetermined period, for calculating a characteristic of the internal resistance value versus the temperature of the exhaust gas sensor 2 from both the internal resistance of the exhaust gas sensor and the environmental temperature, for renewing and storing them, and for calculating a temperature of the exhaust gas sensor 2 from the internal resistance of the exhaust gas sensor 2 in operation, which is measured in operation, and also from the characteristic of the internal resistance value versus the temperature.

摘要： A method and arrangement for measuring the temperature of hot gases present in a hot gas space. A portion of the hot gases is mixed in a mixing space arranged inside the hot gas space with a cooler gas. The temperature of the gas mixture is measured with a thermocouple which is provided in the mixing space. The gas mixture is guided past the thermocouple to determine the temperature of the hot gases from the measured temperature of the gas mixture. The hot gas space is located in the combustion chamber of a gas turbine.

摘要： A temperature sensing device for an internal-combustion engine includes a carrier structure, a first sensor element accommodated on the carrier structure, a second sensor element also accommodated on the carrier structure, an engine air guiding device for feeding an engine intake air flow to the first sensor element, and a radiator air guiding device for feeding a radiator air flow passed through an engine radiator to the second sensor element. By way of a compact constructional unit, which can be preassembled, it is possible to centrally sense the temperatures of the two air flows. The obtained measuring signals can be coupled into a cable tree system provided on the vehicle side while the cabling expenditures are reduced.

摘要： A total air temperature probe positionable on a surface of an aircraft for measuring total air temperature includes an inlet scoop which receives airflow from free stream airflow moving toward the inlet scoop from a first direction. A first portion of the airflow entering the inlet scoop exits the probe through a main exit channel. A second portion of the airflow enters a TAT sensor flow passage, which extends longitudinally along an axis. This axis is oriented to form an angle of less than 90 degrees with the first direction from which the free stream airflow moves toward the inlet scoop. A sensor assembly extends longitudinally in the sensor flow passage and measures a total air temperature of airflow through the sensor flow passage. By increasing the angle through which the internal air turns, better inertial extraction of ice and water particles is realized. As a result, sensor clogging from accreted ice is significantly reduced. A second improvement is achieved by repositioning the sensor element to be more in-line with the internal air flow direction. This helps lower DHE by minimizing heated boundary layer spillage onto the sensing element.

摘要： A multipoint temperature sensor for measuring fluid temperature in a duct includes multiple thermistors of equal resistance, spaced apart in a circuit. Each thermistor has a positive lead and a negative lead for connecting electrically with the circuit. Wires connect the thermistors such that half of the thermistors are placed in parallel with the other half of the thermistors. The total number of thermistors in the circuit is a perfect square. Shrinkwrap fits over the thermistors and the leads. Tabs disposed on bridging clips bend around the shrinkwrap and the wires on either side of each thermistor such that the tabs do not overlap the leads. All the wires between adjacent thermistors are contained in a single, plenum rated sheathing.

摘要： A thermowell assembly (20) shown in FIG. 2 is positioned in a pipeline (10) for sensing the temperature of the fluid medium in the pipeline (10) for transmitting the sensed temperature to a meter (12). A temperature sensing probe is received within a temperature conducting tube (36) forming a thermowell and having a plurality of annular fins (40) extending thereabout. In the embodiments of FIGS. 1-7, a liquid (50) is provided in an annular space between the thermocouple (28) and the temperature conducting tube (36). Non-metallic members (70, 28, 80) are positioned between the pipeline (10) and the temperature transmitting tube (36) to isolate thermocouple (28) from ambient changes in the temperature of metal pipeline (10) which may result in an error in the temperature of the flow medium sensed by the thermowell assembly (20). High temperature embodiments shown in FIGS. 4 and 5 do not contain any non-metal components and provide a minimal metal to metal contact between the metallic temperature conducting tube (36B) of the thermowell (20B) and the adjacent metal mounting structure (52B, 62B). The embodiments shown in FIGS. 8-12 illustrate a temperature sensing probe comprising a temperature sensing assembly (80F, 80G) mounted within the internal bore (37F, 37G) of the finned tube (36F, 36G). The temperature sensing assembly (80F, 80G) includes a carrier (82F, 81G) with epoxy (96F, 96G) mounting a temperature sensing element (93F, 82G) within the carrier (82F, 81G).

摘要： The sensor has an outer member 10 formed with an upwardly directed hole 12 having an open upper end 14. An inner member in the form of a tube 16 is provided having a lower portion 18 positioned in the hole 12 and an upper portion 19 which projects above the outer member 10. Solar radiation applied to the upper portion 19 of the tube 16 creates a chimney effect which causes air to flow upwardly inside the tube 16 and downwardly from the open upper end 14 through a space 22 between the inner and outer members 10, 16. Sensing devices 24, 26 for sensing temperature and humidity are arranged within the outer member 10 and in the air flow path.
