  2. Thermocouple - Wikipedia

    en.wikipedia.org/wiki/Thermocouple

    A thermocouple (the right most tube) inside the burner assembly of a water heater Thermocouple connection in gas appliances. The end ball (contact) on the left is insulated from the fitting by an insulating washer. The thermocouple line consists of copper wire, insulator and outer metal (usually copper) sheath which is also used as ground. [33]

  3. Thermostat - Wikipedia

    en.wikipedia.org/wiki/Thermostat

    Built into the thermostat is a provision for enhanced temperature control using anticipation. A heat anticipator generates a small amount of additional heat to the sensing element while the heating appliance is operating. This opens the heating contacts slightly early to prevent the space temperature from greatly overshooting the thermostat ...

  4. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    Time response is measured by immersing the sensor in water moving at 1 m/s (3.3 ft/s) with a 63.2% step change. Size A standard RTD sheath is 3.175 to 6.35 mm (0.1250 to 0.2500 in) in diameter; sheath diameters for thermocouples can be less than 1.6 mm (0.063 in). Accuracy and stability requirements

  5. Thermowell - Wikipedia

    en.wikipedia.org/wiki/Thermowell

    Thermowells are typically installed in piping systems and subject to both hydrostatic and aerodynamic forces. Vortex shedding is the dominant concern for thermowells in cross-flow applications and is capable of forcing the thermowell into resonance with the possibility of fatigue failure not only of the thermowell but also of the temperature sensor.

  6. Heating element - Wikipedia

    en.wikipedia.org/wiki/Heating_element

    A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule heating .

  7. Tube furnace - Wikipedia

    en.wikipedia.org/wiki/Tube_furnace

    A tube furnace is an electric heating device used to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis. One possible design consists of a cylindrical cavity surrounded by heating coils that are embedded in a thermally insulating matrix. Temperature can be controlled via feedback from a thermocouple.
