Condition: 100% Brand New Item Type:K Type Thermocouple Color: Green Material: Silica Gel Index number: K Temperature Measurement Range: 0-200 Probe Material: Stainless Steel Probe Size: Approx. 5x30mm/0.2x1.2in (DiameterxLength) Wire: Approx. 0.2mm/0.008in (the surface is soft silicone, 2 strand wires and 7 strand copper wires) Terminal: U-shaped terminal The basic principle of thermocouple temperature measurement: 2 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 two The phenomenon 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, electric power, environmental protection, etc., to achieve temperature measurement and direct contact with the measured object.
