Why use a thermocouple compensating conductor

Since you ask, thermocouple temperature measurement purposes can be achieved why using thermocouple compensation wire? It shall be from the perspective of the actual use of temperature measuring.

in general, in order to facilitate the monitoring and measuring instrument operation of instrument will be placed on basic constant temperature and to facilitate the

placed console, away from the actual temperature measuring point has a certain distance. In the distance, in general situation is more complex,

passes through power supply, for example, have electromagnetic interference and so on, and may often be the role of external force. While using thermocouple wire may cause the error of measurement, use is easy to be damaged, often need to change, and so on. And thermocouple wire materials are generally more expensive, if used for long distances, the cost is very high. All these, is the use of the cause of the compensating conductor.

to sum up, with the compensation wire has the following advantages:

1) Improve physical properties and mechanical properties of thermocouple temperature measurement circuit, using multi-strand wire core or small diameter flexible compensation wire line can be improved, convenient wiring, also can adjust circuit resistance or blocking interference;

2) Measuring circuit to reduce costs, distance when the thermocouple and measuring devices, and using the compensating conductor can save a lot of thermocouple material, especially when using the precious metal thermocouple.
