As one of the oldest and most widely used temperature sensors, Versatile Thermocouple plays an important role in many fields such as industry, medicine, and home due to its simple, reliable and versatile characteristics.
Based on the Seebeck Effect, thermocouples are formed by welding two wires of different metals together to form a junction (thermocouple junction). When there is a temperature difference between the two ends, a small voltage is generated. This voltage is proportional to the temperature difference. By measuring the voltage and combining it with calibration data, an accurate temperature reading can be obtained.
The main features of Versatile Thermocouple include:
Fast response: Thermocouples can respond quickly to temperature changes and are suitable for scenarios that require real-time monitoring.
Wide temperature range: From very low -270°C to very high 2300°C, thermocouples can cover a wide range of temperatures.
Flexibility: Thermocouple probes can be designed in a variety of shapes and are suitable for measuring the temperature of liquids, gases or solid surfaces.
Economical: Compared with other temperature sensors, thermocouples are low-cost and easy to install and maintain.
Versatile Thermocouples are divided into several types according to the different metal materials used, each type has its own unique application range and advantages and disadvantages.
J-type thermocouple: The most commonly used type, suitable for general industrial applications, with good stability and long service life. K-type thermocouple: Widely used in industry and laboratories, favored for its high accuracy and corrosion resistance. T-type thermocouple: Suitable for low-temperature measurement, often used in medical equipment and food processing industries. R-type thermocouple: Suitable for high-temperature measurement, often used in kilns and gas turbine engines.
Versatile Thermocouple plays an important role in multiple industries due to its versatility and reliability.
