The thermocouple compensating wire is used for thermocouple extension which serves as the signal compensation during the thermocouple signal transmission and helps make temperature measurement accurate. On contrary, a normal wire can only transmit voltage and current.

Because of the low cost, the wide range of temperature measurement capability (especially in high temperature measurement e.g. K thermocouple can measure the temperature of over 1000 ℃), as well as the diversity of thermocouple, it becomes the most widely used temperature sensor in the industrial sites. The thermocouple temperature measurement system consists of the temperature thermocouple, the corresponding compensating wire, the display/control panel, the PLC system as well as the DCS system. In the thermocouple circuit, after applying the compensating wire, the thermocouple electric potential value is only related to the measured temperature as well as the temperature of the connection point between the compensation wire and the display/control panel. The thermocouple compensating wire is used to extend the hot electrode (i.e., moving the thermocouple reference end) and also save the cost of thermocouple materials.

In order to fully exploit the advantages of thermocouple compensating wires, we need to understand its operation principle, function, applying method as well as some other aspects that need special attention. To properly use the thermocouple compensating wire, the technician needs to understand the operation principle of the thermocouple as well as the compensating wire.Alsothey are requiredto have work ethic and a strong sense of responsibility. In industrial production, the thermocouple as the temperature sensor is widely used in the temperature measurement and control, thus people are very familiar with it. However, using it without proper method, big deviation of temperature measurement and control could occur which might even lead to serious economic losses. In summary, we need to avoid the error mentioned above in order to ensure the accuracy of the thermocouple temperature measurement. welcome to get more details at www.super-instrument.com.
