You need to use in the thermocouple compensation wire matters needing attention

First is the choice of thermocouple compensation wire, can be according to the types of thermocouple and occasion to correct choice you need to use the compensating lead wires, such as k type thermocouple is can choose corresponding compensation conductor, need according to the use of different occasions, to determine the scope of work and temperature, under normal circumstances of kx type thermocouple temperature should be 0 1200 ℃, the error of plus or minus 2. 5 ℃ or so.

with thermocouple and the compensating conductor contact connection, and thermocouple terminal near, as far as possible is to keep the temperature of the two contact is the same, and connection to the instrument temperature should be consistent, because the instrument cabinet will have fan, so cannot be fan blows directly to the contact. Is the length of the used again, you should know that in fact the thermocouple signal is relatively low, basic in microvolt level, so if the distance is too long, because the signal is very weak, coupled with the high voltage in the environment may have on the interference, so will surely lead to the signal of thermocouple weaker, serious word will directly lead to inaccuracy of measurement. Is thermocouple wiring, at the time of the compensating conductor wiring can be far away from the interference sources and power lines, if is to avoid not to drop, so also should choose to cross wiring has come, can't parallel wiring.
