Thermocouple

Thermocouple is a common temperature measurement and control device, which uses the thermoelectric effect of the contact point of two different metal materials to measure temperature. When the two contacts of the thermocouple are at different temperatures, a voltage is generated that is proportional to the temperature difference, and this voltage can be measured to determine the temperature. | Type J thermocouple temperature measuring device, it is based on the principle of thermoelectric effect, type J thermocouple temperature range: Type J thermocouple operating temperature range is about -210°C to 1200°C, but the most commonly used range is from 0°C to 750°C. | Type K thermocouple temperature measuring device, it is capable of measuring from -200 degrees Celsius to +1250 degrees Celsius, is a widely used thermocouple type. It belongs to a type of thermocouple, which is a temperature sensor that measures temperature by measuring the electrical potential difference generated at different temperatures by the connection points of two different metal materials. |PT-100 thermocouple temperature sensor is a resistance temperature detector (RTD). PT" stands for Platinum, and "100" means its resistance is 100 ohms at 0 ° C. The PT-100 is an accurate sensor for measuring temperature because its resistance is very stable and linear with temperature.
