3, the error introduced due to the thermal inertia of the thermocouple indicated value of the thermal inertia of the instrument behind the measured temperature changes, during the rapid measurement of this effect is particularly prominent. It should be fine as far as possible the hot electrode, thermocouple protection tube diameter smaller. When the price of standard thermocouple temperature conditions permit, or even take away the protective tube. Because of the lag measurements, thermocouple temperature fluctuations of the detected amplitude than the furnace temperature fluctuation amplitude is small. Measurement lag, the smaller the amplitude fluctuation thermocouple, the difference between the actual oven temperature and the greater. When using a large time constant thermocouple or temperature, the temperature fluctuations, although a small instrument display standard thermocouple offer, but the actual oven temperature fluctuations may be significant. Not installed correctly, the thermal conductivity and time lag error standard thermocouple distribution, which is the main error of the thermocouple in use. 4, when the high temperature thermal error, such as a layer of ash on the protection tube, dust attached to the above standard thermocouple, the resistance increases, hinder heat conduction, when the temperature is lower than the true value showing the value of the measured temperature. Therefore, we should keep the outside clean thermocouple protection tube to reduce errors. Standard thermocouple sales force _ _ standard thermocouple measured the lowest price since the instrument measured by the Shanghai Automation Instrumentation Co., Ltd ..
