In North America it is typical that the negative lead is red in accordance with ASTM E However, the most widely used global standard for thermocouple wires. Type K thermocouples have a useful temperature range of negative to 1, degrees Celsius. A type K thermocouple has one red wire and one yellow wire. Also the negative (-). Thermocouple wire (Yellow on the outside) · Green Wire = PLUS (+) · White Wire = MINUS (-) · The thermocouples are marked with a (+) and (-). For Types B, R, and S, the color codes relate  . and thermocouple products. In the United States, thermocouple-grade wire usually has an overall brown jacket. A type K thermocouple has one red wire and one yellow wire. A type J thermocouple has one red wire and one white wire. In ANSI color coding, the red wire of a thermocouple is negative, and the positive wire is color coded to the type of thermocouple. Type K thermocouples have a useful temperature range of negative to 1, degrees Celsius. International thermocouple wire codes. Thermocouple wire colors.

A type K thermocouple has one red wire and one yellow wire. These types of thermocouples are suggested to be used in the environment of inert or oxidation. The color for these thermocouples is either red or white. Type K: The type K thermocouple is having chromel as their positive leg and an alumel as their negative leg. Alumel is having 5 percent nickel and rest is silicon and aluminum.

    • This does confuse some electricians since in electrical circuits the red wire is normally the positive leg so care must be taken. Each Thermocouple has a specific color code, the most predominant are the color codes included in the standards ANSI/ASTN E and IEC In ANSI/ASTM E, the negative wire is always the red wire. Additionally. Thermocouple grade wire normally has a brown overall jacket. For Types B, R and S the color codes relate to the compensating cable normally used. In North America it is typical that the negative lead is red in accordance with ASTM E However, the most widely used global standard for thermocouple wires  . The positive conductor is insulated with a colour, for example. For all thermocouple types the negative conductor is always identified by a white insulation. Each Thermocouple has a specific color code, the most predominant are the color codes included in the standards ANSI/ASTN E and IEC In ANSI/ASTM E, the negative wire is always the red wire. Thermocouples do have positive and negative wires, in order to read a correct temperature the polarity needs to be maintained throughout the circuit. The Red wire is generally the negative (-) wire in thermocouples, harnesses, and cables. If the Leads on your thermocouple are reversed, the temperature measured will show to be varying in the opposite direction relative to ambient temperature. Use the chart below to make sure that the positive and negative connections are in the proper order. The standard insulation colors for the different thermocouple. S) and the alloy combination for the positive (+) and negative (-) leads. The negative wire is MORE magnetic than the positive wire. The thermocouples are marked with a (+) and (-). TYPE S (EUROPE) Type S Thermocouple wire (Green on the outside) Orange Wire = PLUS (+) White Wire = MINUS (-) The thermocouples are marked with a (+) and (-). Also the negative (-) is marked with a red marker. ++ Except as further restricted by temperature limits for T/C diameter and insulation tables that follow.
