131-4738 RS PRO Type K Thermocouple 40mm Length, → +150°C

Type K Thermocouple with Silicone Rubber Patch_x000D_ Type K Thermocouples is a device which measures temperatures, it’s made up from two wires which are different materials. When these two wires are joined together, they create an electrical junction. Once the temperature changes at this junction, it creates a voltage which can then be interpreted and read as a temperature. This is commonly known as the “Seebeck Effect”._x000D_ Features & Benefits_x000D_ • Moulded silicone patch thermocouple, Type K_x000D_ • Features a self-adhesive patch with aluminium foil backing_x000D_ • 1-2meter long insulated twin-twisted wire_x000D_ • Resistant to most oil and chemicals_x000D_ • Has a temperature range of -50°C to +150°C_x000D_ • Three year warranty_x000D_ • Thermocouple junction encapsulated in a silicone rubber patch with self0adhesive aluminium foil backing_x000D_ Types of Thermocouples_x000D_ • Type K Thermocouples: Type K is one of the most common types of thermocouple. They’re popular due to their low cost, the Type K are accurate, provide reliability and have a wide temperature range._x000D_ • Type J Thermocouples: Type J is also very common and widely known for their low cost, good performance and reliability. Can hold its own in higher temperature ranges, but this can shorten its lifespan._x000D_ • Type T Thermocouples: Type T offers stability and consistency, you can typically expect to use type T in exceptionally low temperature situations - such as freezing._x000D_ • Type N Thermocouples: Type N shares similar accuracy and temperature limits as Type K. Type N is slightly higher in their price range._x000D_ • Type L Thermocouples: Type L specialise in measurements of liquids such as liquid metals. They’re commonly used in heating and apparatus engineering. This type of thermocouple is also cost effective, efficient and reliable._x000D_ Note_x000D_ Electrical isolation between foil and lead out wires cannot be relied upon_x000D_ Standards_x000D_ Colour coded to former British Standards – BS1843-1952
