Micro thermal resistance

Micro thermal resistanceAlso known as a resistance thermometer, it is an instrument that uses semiconductor materials such as metal conductors or metal oxides as temperature measuring media to measure temperature by measuring the resistance value that changes with temperature. Its working principle is based on the characteristic of the resistance value of conductors or semiconductors changing with temperature.

Characteristics and advantages

High precision: Due to its fine structure, it can more accurately sense temperature changes and is suitable for situations that require high-precision temperature measurement.

Good stability: Metal conductors or metal oxides as temperature measuring media have good stability and reliability, and can maintain measurement accuracy for a long time.

Widely applicable: Suitable for various complex and variable temperature measurement and control scenarios, such as chemical, petroleum, metallurgical, power and other industries.

Type and specifications

There are multiple types and specifications to meet different application requirements. For example, according to the material, it can be divided into platinum thermistor, copper thermistor, etc; According to their structure, they can be divided into armored thermal resistors, thin-film thermal resistors, etc. Specific specifications such as temperature measurement range, nominal pressure, flow rate, etc. need to be selected according to the actual application scenario.

Micro thermal resistanceApplication scenarios

In the industrial field, it is widely used in pipelines, heat exchangers, reactors, boilers, and the inner walls of storage tanks in industries such as chemical, petroleum, metallurgy, and power, to monitor the temperature changes of internal fluids or materials in real time.

Household appliances: Built in near the refrigeration system and heating elements in household appliances such as refrigerators, air conditioners, and washing machines, used to monitor and regulate the operating temperature of the system.

Electronic and Automation Control: Plays the role of temperature compensation in precision electronic devices and instruments, ensuring the accuracy and stability of electronic systems.

Building HVAC: In building HVAC systems, it is used to monitor the temperature of supply and return air, and thereby regulate the working status of the entire system.
