What materials are used for the positive and negative conductors of KX compensation wire?
Compensation wires are generally replaced with wires with the same electron density as thermocouples. The connection between compensation wires and thermocouples is usually clear, with the positive pole of the thermocouple connected to the red wire of the compensation wire and the negative pole connected to the remaining color. The material of most compensation wires is copper nickel alloy. A specialized wire used to extend the cold end of a thermocouple to a location far away from high temperatures and where the temperature is relatively stable. Essentially, it is a thermocouple composed of two different metals. Within a certain temperature range, its thermoelectric properties are basically the same as those of the main thermocouple. By connecting the compensating wire to the cold end of the thermocouple, the temperature signal output by the thermocouple can be transmitted to a control room several tens of meters away and sent to display or control instruments. This is equivalent to extending the thermocouple to a constant temperature location, solving the problem of high temperature and temperature instability caused by the cold end of the thermocouple near the hot equipment. Easy to use, it is often used in thermocouple installation. They are specialized wires, and one type of compensation wire can only be used in conjunction with the corresponding type of thermocouple, and the positive and negative polarities cannot be reversed.
