K type thermocouple color code

There are many types of thermocoupleseach with its own unique characteristics. You can easily identify a thermocouple type by the colors of its wire insulation.

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, these find there way into the UK market. 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 Other countries to have their own standards include Japan and France but these are rarely seen if ever. 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.

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.

What follows is specifically for IEC colour code and is not applicable to the other standards mentioned. Outside Europe Other countries outside of Europe have their own standards and on occasion, these k type thermocouple color code there way into the UK market. For type J the positive conductor is strongly magnet as it is pure Iron.

K type thermocouple color code

Japanese to JIS C Used for interconnecting Type "K" thermocouples and instrumentation as an alternative to Type "K" material. Color coded for use as a compensating cable for Type "K" thermocouples. This compensating cable can also be used for extending Type "T" thermocouples. Many low temperature and cryogenic applications.

By using a magnet, test the negative leg of the cable. No other thermocouple uses Copper as a conductor so this can aid positive identification. Click to expand the image. Thermocouple Colour Code. Lost your password? A type J thermocouple has one red wire and one white wire. How does a Thermocouple Work? In the UK and Europe, the most widely used colour code for Type B thermocouple cable is to the international IEC standard which is as follows:. The jacket colour of the cable where the cable has a jacket is the same colour as the positive conductor insulation. Type E thermocouples have a temperature range of negative to degrees Celsius. You can easily identify a thermocouple type by the colors of its wire insulation. There is no compensating cable available for Type J, however the extension cable is relatively inexpensive. A type T thermocouple has one red wire and one blue wire.

The German standard for type J is still relatively commonly used as it is a common type in plastics machines but there may be cause for confusion as the colour code, Red and Blue with a Blue jacket, is identical to the American ANSI colour code for type T! With respect to other colour coding standards, there are a couple of other difficulties in identifying type J. The jacket colour of the cable where the cable has a jacket is the same colour as the positive conductor insulation. A type J thermocouple has one red wire and one white wire. 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:. It can be assumed that as Type N thermocouples become more popular the compensating cable will start to be produced. Assuming the cable has a jacket then check this first. There is still a demand for cables and sensors to be supplied to obsolete colour codes, such as BS
