  2. Heat flux sensor - Wikipedia

    en.wikipedia.org/wiki/Heat_flux_sensor

    A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor. The measured heat rate is divided by the surface area of the sensor to determine the heat flux . Silicon encased heat flux sensor for measurements on rugged surfaces.

  3. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    Proportional–integral–derivative controller. A proportional–integral–derivative controller ( PID controller or three-term controller) is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control.

    A sailor checking the temperature of a ventilation system. A pyrometer, or radiation thermometer, is a type of remote sensing thermometer used to measure the temperature of distant objects. Various forms of pyrometers have historically existed. In the modern usage, it is a device that from a distance determines the temperature of a surface from ...

    en.wikipedia.org/wiki/Thermostat

    The advantage of the low voltage control system is the ability to operate multiple electromechanical switching devices such as relays, contactors, and sequencers using inherently safe voltage and current levels. [15] Built into the thermostat is a provision for enhanced temperature control using anticipation.

  6. Temperature control - Wikipedia

    en.wikipedia.org/wiki/Temperature_control

    Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature. [ 1] Thermoregulation is the act of keeping the body at a ...

  7. Bang–bang control - Wikipedia

    en.wikipedia.org/wiki/Bang–bang_control

    In control theory, a bang–bang controller ( hysteresis, 2 step or on–off controller), is a feedback controller that switches abruptly between two states. These controllers may be realized in terms of any element that provides hysteresis. They are often used to control a plant that accepts a binary input, for example a furnace that is either ...
