The purpose of using compensating wires:
(1) Move the reference end of the thermocouple from a high-temperature location to a place with more stable environmental temperature.
(2) Saves a significant amount of valuable and rare metal materials used in the manufacturing of thermocouples.
(3) Using compensating wires facilitates installation and laying of the lines.
(4) Replacing thermocouples with compensation wires of larger diameter and higher conductivity can reduce the resistance in the thermocouple circuit, benefiting measurement and automatic control.
Be mindful of the following points when using compensating conductors:
(1) Various compensation wires are only compatible with their corresponding thermocouple models. This means that the thermoelectric properties of each thermocouple and its corresponding compensation wire must be identical within the specified temperature range (0~100℃).
(2) The temperature at the compensation wire and thermocouple connection point must not exceed the specified operating temperature.
(3) When compensating conductors and thermocouples are connected to instruments, the positive and negative poles must not be reversed, and the two pairs of connection points must be at the same temperature.
(4) Select the wire diameter of the compensating cable based on the line resistance requirements of the instrument to be matched.
