Thermocouple cold junction is too close to the furnace so that the temperature exceeds 100 ℃; thermocouple should be installed as far as possible away from strong magnetic fields and strong electric field, it should not be the thermocouple and power cables in the same wire-bound to introduce a catheter to avoid interference caused by error; Thermocouples can not be installed in a small area of ??the measured medium flows, when the measuring tube with the gas temperature at the thermocouple type K thermocouple specification, the thermocouple must be installed against the direction of flow, and full contact with the gas. 3, the error introduced due to the thermal inertia of the thermal inertia of the thermocouple indication value of the meter is measured behind the K-type thermocouple temperature change prices, during this effect particularly fast measurement. It should be fine as far as possible the hot electrode, thermocouple protection tube diameter smaller. When the temperature conditions permit even take away the protective tube. Due to the presence of K-type thermocouple measuring lag, detected by the thermocouple temperature fluctuations than the furnace temperature fluctuation amplitude of small amplitude. 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 in the instrument display, although very small, but the actual oven temperature fluctuations may be significant. K-type thermocouple type K thermocouple Shandong manufacturers _ _ force measuring instrument since K-type thermocouple measuring the force provided by the Shanghai Automation Instrumentation Co., Ltd. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) strong, credible, in Shanghai Zhabei District, flow meters and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the force measured since the instrument into the brilliant and you work for a better future!
