Due to the thermal inertia of thermocouples, the indicated value of the instrument lags behind the changes in the measured temperatureInspection instrument manufacturerThis effect is particularly prominent when conducting quick selection measurements. soWholesale of inspection equipmentThermocouples with thinner thermoelectric electrodes and smaller protective tube diameters should be used as much as possible. When the temperature measurement environment permits, the protective tube can even be removed. Due to measurement lag, the amplitude of temperature fluctuations detected by thermocouples is smaller than that of furnace temperature fluctuations. The larger the measurement lag, the smaller the amplitude of the thermocouple fluctuation, and the greater the difference from the actual furnace temperature. When using a thermocouple with a large time constant for temperature measurement or control, although the temperature displayed on the instrument fluctuates very little, the actual furnace temperature may fluctuate greatly. In order to accurately measure temperature, a thermocouple with a small time constant should be selected. The time constant is inversely proportional to the heat transfer coefficient and directly proportional to the diameter of the thermocouple's hot end, the density of the material, and the specific heat. To reduce the time constant, besides increasing the heat transfer coefficient, the most effective way is to minimize the size of the hot end as much as possible. in usePrice of inspection equipmentUsually, materials with good thermal conductivity are used, such as thin pipe walls and small inner diameters
