Watt thermistor

1. What isWatt thermistor？

Watt thermistorIt is a temperature sensor commonly used to measure temperature in high-temperature environments. Its principle is to use the characteristic of metal resistance changing with temperature to measure temperature, so it is also known as thermal resistance. The name Vawen thermal resistance comes from the German physicist Wheatstone and his invention of the bridge principle. I

2. Structure and Working Principle of Wawen Thermal Resistance

Wawen thermal resistance is made of metal wire or foil, usually using platinum or chromium alloy as the surrounding material. The structure of thermal resistors is generally divided into two types: one is to directly make metal wires or foils into a spiral shape, and the other is to wrap metal wires into foils and wrap them inside ceramics, glass, or metal tubes. In high-temperature environments, the resistance value of a thermistor increases with the rise of temperature, and this relationship can be described by the temperature coefficient of the thermistor.

3. Advantages and disadvantages of Wawen thermal resistance

Wawen thermal resistance has the advantages of fast response speed, high accuracy, and good stability, and is therefore widely used in temperature measurement applications in high-temperature environments. However, there are also some drawbacks to Wawen thermal resistance, such as high price, susceptibility to mechanical actuation and electromagnetic interference.

4. Application Fields of Wawen Thermal Resistors

Wawen thermistor is widely used in temperature measurement fields in high-temperature furnaces, aerospace, energy, chemical and other industries. In high-temperature furnace chambers, the Wa Wen thermistor can measure the temperature inside the furnace to control the furnace temperature and ensure product quality. In the aerospace industry, Wawen thermistors can be used to measure the temperature of engines to ensure their safe operation. In the field of chemical engineering, Wawen thermistor can be used to measure the temperature inside the reaction vessel to control the reaction process.

In summary, as a temperature sensor in high humidity environments, the Wawen thermistor has important application value in industrial production and scientific research.
