2. List of temperature sensors - Wikipedia

   en.wikipedia.org/wiki/List_of_temperature_sensors

   Electrical temperature sensors. Thermistor - Thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature. [1] Negative Temperature Coefficient (NTC) thermistors exhibit a decrease in electrical ...

3. Resistance thermometer - Wikipedia

   en.wikipedia.org/wiki/Resistance_thermometer

   Resistance thermometer. Resistance thermometers, also called resistance temperature detectors ( RTDs ), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt ...

4. Thermocouple - Wikipedia

   en.wikipedia.org/wiki/Thermocouple

   Thermocouple. A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature.

5. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   A thermometer is a device that measures temperature (the degree of hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space). 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 ...

6. Thermistor - Wikipedia

   en.wikipedia.org/wiki/Thermistor

   Thermistor. A thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor . Thermistors are categorized based on their conduction models. Negative-temperature-coefficient (NTC) thermistors have less ...

7. Thermoelectric effect - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_effect

   The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. [ 1] A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a ...
