K type thermocouple color code

Thermocouples of all different types have their own colour coding to aid identification however this is not necessarily as easy as it may seem. As well as each thermocouple type having its own colour code, there are various national and international standards each having their own colour code system. It is important to positively identify which standard is being used before you can identify the thermocouple type. Other countries outside of Europe have their own standards and on occasion, k type thermocouple color code, these find there way into the UK market.

There are many types of thermocouples , each with its own unique characteristics. You can easily identify a thermocouple type by the colors of its wire insulation. In ANSI color coding, the red wire of a thermocouple is negative, and the positive wire is color coded to the type of thermocouple. There are many types of thermocouples, each with its own unique characteristics. A type K thermocouple has one red wire and one yellow wire.

K type thermocouple color code

To help identify the thermocouple type and thermoelement conductor polarity, various colour codes have been developed and are in use around the world. There is still a demand for cables and sensors to be supplied to obsolete colour codes, such as BS In the UK and Europe, the most widely used colour code for Type K thermocouple cable is to the international IEC standard which is as follows:. Occasionally in the UK, American ANSI colours may be found which have a yellow outer sheath with yellow and red conductors as shown below. You may also come across some old redundant colours such as the obsolete BS standard and these are shown in the table below:. Type KCA - This compensating cable conductor combination is little known and generally not available. It should not be confused with the more popular Type KCB as shown below. If suitable to your requirements it can save money where long runs are necessary. In the UK and Europe, the most widely used colour code for Type T thermocouple cable is to the international IEC standard which is as follows:. Type TX extension cable conductors are made from the same constituent elements as Type T thermocouples. There is no compensating cable available for Type T, however the extension cable is relatively inexpensive. In the UK and Europe, the most widely used colour code for Type J thermocouple cable is to the international IEC standard which is as follows:. Occasionally in the UK, American ANSI colours may be found which have a black outer sheath with white and red conductors as shown below. Type JX extension cable conductors are made from the same constituent elements as Type J thermocouples.

For some cables, particularly glass fibre insulation, the colour coding is not very clear. This colour is different for each type.

.

You will see in the table below, that commonly, negative wires are red, the outer sheath for thermocouple grades is brown and the positive lead is color coded according to thermocouple type. For extension grade cables this positive leg color is also carried over to the outer insulation color. Fiberglass insulated wires follow the same system but have a colored tracer rather than a solid color. We also have an extensive range of data sheets available for all our Thermocouple Grade Wire and Thermocouple Extension Wire. Extension wire can offer a cost advantage. For base metal thermocouples, the wire is the same composition as the corresponding thermocouple.

This is by far the most common thermocouple colour code system used today and is the standard colour coding we supply for our thermocouples unless otherwise requested. More About Thermocouples. There is no compensating cable available for Type J, however the extension cable is relatively inexpensive. In the UK and Europe, the most widely used colour code for Type K thermocouple cable is to the international IEC standard which is as follows:. There are many types of thermocouples , each with its own unique characteristics. Finally, a type E thermocouple has one red wire and one purple wire. Thermocouple Colour Code. Obsolete codes Other colour codes which are now officially obsolete but may still be used, particularly on older machinery, are the old British Standard colour code which complied with BS and BS also the German DIN colour codes which complied with DIN You can easily identify a thermocouple type by the colors of its wire insulation. What are the International Standards for Thermocouple Colours?

Japanese to JIS C Used for interconnecting Type "K" thermocouples and instrumentation as an alternative to Type "K" material.

Type NX extension cable conductors are made from the same constituent elements as Type N thermocouples. Although there is a designated compensating cable for Type N, it is not at present readily available. With respect to other colour coding standards, there are a couple of other difficulties in identifying type J. Lost your password? Cookie settings OK. In the UK and Europe, the most widely used colour code for Type S thermocouple cable is to the international IEC standard which is as follows:. Thermocouples of all different types have their own colour coding to aid identification however this is not necessarily as easy as it may seem. It is also completely unique when compared to other standards. It can be assumed that as Type N thermocouples become more popular the compensating cable will start to be produced. Type K thermocouples have a useful temperature range of negative to 1, degrees Celsius. Thermocouple Wire Colour Code. Type K would be red and type E would be brown. As mentioned already, the thermocouple colour coding system seems straight forward at first glance but there are some pitfalls to be aware of and these will be described as follows. This is by far the most common thermocouple colour code system used today and is the standard colour coding we supply for our thermocouples unless otherwise requested.
