What is a thermocouple? What are the types of thermocouples? How high a temperature can a thermocouple be used? These topics are being explained.
What is a thermocouple? What are the types of thermocouples? How high can thermocouples be used in Celsius and Fahrenheit? This content explains these topics. Generally, in the industrial sector, either resistance temperature detectors or thermocouples are used for temperature measurement. A thermocouple consists of two different metals that are connected at the measurement point. Thermocouples with a solid weld of the two dissimilar metals have high vibration resistance, making them commonly used in the industry. When the temperature at the thermocouple measurement point rises or falls, the electron density of the two metals changes. This change in electron density generates a voltage at the output connection point. Thermocouples operate based on the principle of comparative measurement. In other words, the temperature at the measurement point is expressed as a thermoelectric voltage relative to the temperature at the output connection point. Since temperature measurement at the measurement point cannot be done with just the temperature difference, cold junction compensation is necessary. This ensures that the measurement results are not affected by the ambient temperature around the connection terminals. 00:00 Introduction 00:04 How does a thermocouple work? 00:55 Cold junction compensation 01:25 Voltage curve of thermocouples and material pairing 01:58 Types of thermocouples

Company information
"WIKA" is a global manufacturer of measurement instruments headquartered in Germany. For over 70 years, it has maintained a top-class market share in measurement instruments as a specialized manufacturer in the global market. It is the number one manufacturer in Europe for measurement instruments, including pressure gauges and thermometers, widely used in the manufacturing industry, such as plant equipment, and is among the top manufacturers in the world. Currently, it operates in over 40 countries worldwide and boasts a total workforce of 9,000 employees, making it a global company. The Japanese branch has seen a steady increase in performance and has a track record of transactions with major companies across a wide range of industries, including large heavy industry manufacturers. The brand power and product strength are so high that it is often said, "Measurement instruments are WIKA." With bases in over 40 countries, as Japanese companies become more active in expanding overseas, the demand has also increased, and the company's strength lies in its ability to handle everything, including follow-up after product installation. Because it offers a wide range of products not found in other competitors, it can provide comprehensive solutions to meet customer needs.
