KType Thermocouple Probe Twisted Pair Shielded Screw Temperature Sensor 0200℃ Green M6x50mm(3meter ) Item Type: K-Type Thermocouple Index Number: K Temperature Measurement Range: 0-200℃ Probe Material: Stainless steelProbe Style: Screw type Probe Specification: Diameter: M6, Length: Approx. 50mm / 2inNumber of Wires: 2 Number of Copper Wires in the Wire: 7 Diameter of Copper Wires in the Wire: 0.2mmLine Length: Approx. 1meter / 3.3ft 2meter / 6.6ft 3meter / 9.8ft Terminal: U-shaped terminal The Basic Principle of Thermocouple Temperature Measurement: Two conductors of different materials or semiconductors A and B are welded together to form a closed loop. When there is a temperature difference between the two attachment points 1 and 2 of conductor A and B, the situation of generating electromotive force and forming a current in the loop is called the thermoelectric effect. Thermocouples use this effect to work Application: Thermocouples are widely used in various enterprises and institutions such as petroleum, water conservancy, chemical industry, metallurgy, electricity, environmental protection, etc., to achieve temperature measurement and direct contact with the measured object
