From RS Pro a range of type K and T fine wire thermocouple temperature sensors conforming to IEC 584 -3 standards. These thermocouples have a fast response welded exposed junction and are terminated with a miniature flat pin plug colourfor a quick and easy connection. The twin twisted leads of these thermocouple sensors are insulated with durable Teflon PFA.

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

• Welded, exposed junction with fast response
• Durable PFA insulation for resistance to oils, acids and fluids and proviision of good mechanical strength and flexibility
• Tolerance to IEC 584-3 class 1 for optimum performance
• Miniature plug termination for quick and easy assembly
• Temperature range of -75 to +250°C

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