Type K, Sheathed Thermocouples with Over moulded Standard Connector


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 created a voltage which can then be interpreted and read as a temperature. This is commonly known as the “Seebeck Effect”.

Features & Benefits


• Hot junction underground

• Features mineral pressed insulation

• Three year warranty

• The highly flexible and can be formed to suit many different applications and processes

• Temperature ranges from -50 ºC to +1200 ºC

• Ø available: 1.5mm, 3mm, 4.5mm, 6mm

• Universally used

• Reagent & Strong

Typical Applications


• This Type K Industrial Mineral Probe with an underground junction is suitable for corrosive media, although the thermal response tends to be slower than others.

• In some typical applications, where more than one thermocouple connects to an associated instrumentation it could be essential to incorporate insulation – this is to avoid spurious signals occurring in the measuring circuits.

Types of Thermocouples


• 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.

• 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.

• 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.

• Type N Thermocouples: Type N shares similar accuracy and temperature limits as Type K. Type N is slightly higher in their price range.

• 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.
