2. Indoor–outdoor thermometer - Wikipedia

   en.wikipedia.org/wiki/Indoor–outdoor_thermometer

   The primary purpose of the indoor-outdoor thermometer is to allow the outside temperature to be indicated inside a building, thus removing the need to go outside to take a temperature reading. They are also used in vehicles, and are particularly useful for municipal vehicles involved in snow and ice clearance. [ 5 ]

3. Permanent downhole gauge - Wikipedia

   en.wikipedia.org/wiki/Permanent_Downhole_Gauge

   A permanent downhole gauge (PDG) is a pressure and/or temperature gauge permanently installed in an oil or gas well. [1] These gauges are typically installed in the tubing in the well and can measure the tubing pressure, annulus pressure, or both.

4. Thermowell - Wikipedia

   en.wikipedia.org/wiki/Thermowell

   A temperature sensor, such as a thermometer, thermocouple, or resistance temperature detector, is inserted in the open end of the tube, which is usually in the open air outside the piping or vessel and any thermal insulation. Thermodynamically, the process fluid transfers heat to the thermowell wall, which in turn transfers heat to the sensor ...

5. Exhaust gas temperature gauge - Wikipedia

   en.wikipedia.org/wiki/Exhaust_gas_temperature_gauge

   An exhaust gas temperature gauge (EGT gauge or EGT sensor) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR).

6. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid. Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer.

7. Heat flux sensor - Wikipedia

   en.wikipedia.org/wiki/Heat_flux_sensor

   The measured time-dependent surface temperature of the gauge and its known thermal properties allow to recalculate the time-dependent heat flux from the heating environment onto the gauge which caused the temperature change of the gauge. This is accomplished by the theory of heat conduction into a semi-infinite body.

9. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...
