RS PRO Type K Exposed Junction Thermocouple 2m Length, 1/0.3mm Diameter → +250°C

From RS Pro a range of Type K and Type T fine wire temperature sensing thermocouples ithat meet ANSI MC96.1 stanards with class 1 tolerance for optimum accuracy. These Type K and type T wire temperature sensors consist of a durable Teflon PFA insulated twin-twisted lead and a single element exposed welded junction for a fast response time.

A thermocouple is a sensor used to measure temperature in a range of different processes and consists of two wire legs made 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

A welded exposed junction is where the thermocouple wires are welded together but are not surrounded by the outer sheath. The ends of the wire are directly inserted into the process. This means the thermocouple has a high sensitivity and response time. Welded exposed junctions are more prone to corrosion and are recommended for measuring flowing or static non-corrosive gas temperatures

• ANSI MC96.1 class 1 tolerance for optimum accuracy
• Class 1 cable specification in accordance with BS EN 60584-3:2008
• Exposed welded junction for fast response
• Durable Teflon PFA insulation for resistance to oils, acid, fluids and good mechanical strength and flexibility
• Temperature ranges from -75 to +250°C

These K Type and T type fine wire thermocouples are ideal for test and development applications including test and measurement, temperature mapping and OEM applications
