Thermocouple Compensation Cable

کابل جبران ترموکوپل کد Usually, wires and cables were used to transmit the information and signal of the temperature sensor to the control and monitoring room or measuring device, but due to the temperature sensor, which creates a junction or connection in the thermocouple, creates a secondary thermocouple and in Pt100 the linear resistance of the interface wire. With the resistance of the sensor, it is necessary to use suitable wires for thermocouple and thermoresistance. To send the temperature signal of the thermocouple, a compensation cable or extension cable should be used to increase the emf created in the connection of the thermocouple to the cable and the interface wire. It is similar to the thermocouple itself and does not cause errors. The best way is to add a wire of the same type of thermocouple, which is known as extention and in the relevant codes is indicated by the letter X after the type of thermocouple. Error and tolerance of this cable example is shown in the table below, which is similar to the thermocouple errors themselves.
