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. In ANSI color coding, the red wire of a thermocouple is negative, and the positive wire is color coded to k type thermocouple color code type of thermocouple.

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.

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:.

It is not unusual for a customer to request a type J thermocouple in fact they have a Pt and vice versa.

Call us at This may be an immersion sensor, a surface sensor, wire or another style of sensor or cable. Click on this link to check the complete thermocouple color code chart. Using a thermocouple temperature controller can ensure you are using the proper process temperatures for your application. The following is a selection of output values for Type K Thermocouples at selected temperatures. Thermocouples are not manufactured to a specific resistance, they measure temperature based on the output voltage they provide. Resistances will vary with conductor size and somewhat with the lot of conductor used.

There is no compensating cable available for Type T, however the extension cable is relatively inexpensive. Type K would be red and type E would be brown. 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. The positive conductor of type T is pure copper. Type E thermocouples have a temperature range of negative to degrees Celsius. This website uses cookies to improve your experience. How to Identify a Thermocouple by Wire Color. A type J thermocouple has one red wire and one white wire. A highly unlikely problem is that of type K and type E colour coding when using the now obsolete British Standard colour coding. I agree to the terms and conditions listed in the Privacy Policy.

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

As such, a lot of cable still in use and being supplied could well be to the historical industry accepted standard shown in the table below. The positive conductor of type T is pure copper. For some cables, particularly glass fibre insulation, the colour coding is not very clear. Remember me Log in. There is no compensating cable available for Type T, however the extension cable is relatively inexpensive. Type E will not have a magnetic conductor.
