How does a thermostat control an electric heating plate
1. When using such electric heating devices, it must be noted that their continuous operating temperature should be less than 240°C, and instantaneous temperature should not exceed 300°C.
2. Guowei silicone electric heating devices can work under pressure, i.e., using an auxiliary pressure plate to make them closely adhere to the heated surface. In this case, heat conduction is good, and when the temperature in the working area does not exceed 240°C, the power density can reach 3W/cm².
3. Under adhesive installation conditions, the allowable working temperature is less than 150°C.
4. In the case of dry burning in air, due to material temperature limitations, the power density should be less than 1W/cm²; under non-continuous conditions, the power density can reach 1.4W/cm².
5. The selection of working voltage follows the principle of high power - high voltage, low power - low voltage, with exceptions for special needs.
6. A power supply that meets the instrument requirements must be used, and thepower socket should be a three-hole safety socket with a ground wire installed.
7. Slight smoke may occur during initial use, which is normal.
8. During use, prevent the heating medium from overflowing the container and entering the box to damage the electrical components.
9. If a malfunction occurs during use, cut off the power supply before performing repairs.
10. Do not operate without liquid (dry burning).
A thermostat, based on temperature changes in the working environment, undergoes physical deformation inside the switch, producing certain special effects that result in a series of automatic control elements that either conduct or break the circuit. It is also called atemperature control switch,temperature protector,temperature controller, abbreviated as thermostat. Alternatively, thetemperature protector transmits the temperature to thetemperature controller, and thetemperature controller issues a switching command, thereby controlling the operation of the equipment to achieve the desired temperature and energy-saving effects. Its application range is very wide, and different types of thermostats are used in many products such as home appliances, motors, refrigeration, or heating.
