Temperature controller
| |
The fluid medium temperature controller is automatically adjusted by the principle of thermal expansion and cold contraction of temperature-sensing fluid and incompressibility of liquid. When the control temperature increases, the thrust generated by the expansion of the temperature sensing liquid will turn down the heat medium to reduce the output temperature; When the control temperature decreases, the temperature sensing liquid shrinks, and the heat medium is turned up under the action of the reset device to increase the output temperature, so that the controlled temperature can reach and maintain in the set temperature range.
Bimetallic temperature controller working principle according to the object thermal expansion cold contraction principle. It is common for objects to expand by heat and contract by cold, but different objects have different degrees of expansion and contract by heat. The two sides of the double gold plate are the conductors of different substances. Under the changing temperature, the double gold plate is bent due to the different degree of expansion and contraction, and the set contact or switch is touched, so that the set circuit (protection) starts to work.
Color temperature type temperature controller, the working principle of some paint in different temperature will produce different color principle. For example, using liquid crystal at different temperatures, you can produce different colors, and then use the camera class color collector to provide different data to the circuit, so as to control the circuit. |
