Thermocouple for Cooker Temperature Compensation

Since the material of the Thermocouple for Cooker is generally more valuable (especially when using noble metal), the temperature of the temperature measuring point is far from the meter, in order to save the cooker thermocouple material, reduce cost, usually use the compensation wire to put the thermocouple cold end (Free end) extends to a relatively stable control chamber, connected to the meter terminal.
It must be pointed out that the action of the Thermocouple for Cooker compensation wire only shows the extension heat electrode, so that the cold end of the thermocouple moves to the meter terminal of the control chamber, it itself does not eliminate the impact of the temperature change on the temperature of the temperature, and does not afford the compensation . Therefore, it is necessary to use other correction methods to compensate for the impact of the temperature measurement at the cold end temperature t0 ≠ 0 ° C. When using the thermocouple compensation wire, you must pay attention to the model. The polarity cannot be attached, the compensation wire and the temperature difference of the thermocouple connection cannot exceed 100 ° C.
