239-4671 RS PRO Type K Thermocouple 5m Length, 1/0.2mm Diameter → +150°C

RS PRO Type K Silicone Patch Thermocouple with Miniature Plug_x000D_ From RS PRO a Type K thermocouple temperature sensor designed for taking surface temperature measurements. The thermocouple lead is made from twin-twist wire with a durable PFA insulation. One end of the lead is terminated with a miniature plug for a quick and easy connection. The other end of the wire is terminated with a self-adhesive moulded silicone patch for attaching to a surface._x000D_ How does a Thermocouple Work?_x000D_ from different metals joined together at their two ends to form two junctions. The hot, or measuring junction is connected to the body whose temperature is going to be measured. The cold junction or reference junction is connected to a body of known temperature. When the measuring junction is placed on something hot a voltage or potential difference between this and the reference junction occurs. This voltage can then be converted into a temperature measurement using thermocouple reference tables. This process is also known as the Seebeck Effect._x000D_ What is a Surface Thermocouple?_x000D_ This thermocouple is designed for measuring the temperature on a surface. Most thermocouples have a sensing tip where there ends of the thermocouple wires are encased in sheaths or protection tubes which do not allow for measuring the temperature of a surface area. In surface temperature sensing thermocouples the exposed welded wire junction is housed in a magnet or adhesive patch which provides a true surface contact. This affixing method allows these thermocouples to be used on many types of surfaces including uneven and circular surfaces. They are also simple to use and easy to replace and position._x000D_ Features and Benefits_x000D_ JIS Type K thermocouple_x000D_ Self-adhesive for surface temperature measurement_x000D_ Resistant to many oils & chemicals_x000D_ PFA 1/0.2mm twin-twisted wires_x000D_ Cable Length: 1 m, 2 m and 5 m available_x000D_ Fitted miniature plug_x000D_ Patch rubber: L. 40 mm x W.13 mm x H. 5 mm_x000D_ Sensor range to 150°C_x000D_ Variants_x000D_ Probe length: 1 m – RS stock no: 239-4669_x000D_ Probe length: 2 m – RS stock no: 239-4670_x000D_ Probe length: 5 m – RS stock no: 239-4671
