The working principle and application of thermal resistance

Thermal resistance is a sensor used to measure high temperatures, and its working principle is based on thermal conduction and changes in resistance values. There are various types of materials such as platinum, copper, nickel, iron, tungsten, etc., especially platinum. This article will introduce the working principle and application of thermoelectric resistors.

The working principle of thermal resistance

The working principle of thermoelectric resistance is based on thermal conduction and changes in resistance values. The thermal resistance sensor consists of two electrical stages, one is high temperature and the other is low temperature. When there is a temperature difference between high and low temperatures, the resistance value of the sensor will change.

In the high-temperature industry, thermal resistance is usually used to measure the temperature of high-temperature steam, gases, liquids, and other materials. The working principle of thermoelectric resistance is to use the resistance value of a metal conductor to vary with temperature. When the surface of a thermoelectric resistor is heated, the resistance value will change. According to the working principle of thermal resistance, the temperature of high-temperature objects can be measured by measuring the resistance value of the thermal resistance.

Several uses of thermal resistors:

Industrial control and testing: Thermal resistors are widely used in industrial control and testing, such as detecting the temperature and pressure of fluids under high temperature and pressure conditions.

Thermistor: Thermistor is a high-temperature sensor commonly used to measure the temperature of high-temperature objects. The thermoelectric resistance is composed of two different materials made of electrical stages. When the heat of a high-temperature object is transferred to the electrical level, the resistance value of the electrical level will change, and the temperature of the object will be measured based on the measured resistance value of the thermal resistance.

Food industry: Thermistors are widely used in the food industry, such as measuring high temperature steam and gases, which can be used to detect the temperature during food processing.

Power industry: Thermal resistors are widely used in the power industry, such as when measuring high-temperature and high-pressure liquids, which can be used to detect the temperature and pressure of the fluid.

In industry, thermal resistance can be applied to multiple industries such as intelligent production, chemical industry, mining, railway, pharmaceuticals, and food industry. The application of thermal resistance is also essential in high-tech fields such as aerospace engineering, Nuclear engineering and original power plant.
