3) the faulty thermocouple removed from the instrument, using a multimeter on ohms measurements (R) * 1 files, two tables with a multimeter to measure thermocouple stick at both ends, the resistance value if the multimeter displays great shows internal thermocouple connection open, replace the same type of thermocouple. Otherwise, there is a certain resistance K-type thermocouple prices, indicating a problem with the input of the instrument, the instrument should be replaced. Because thermocouple materials are generally more expensive (especially the use of precious metals), and the measurement points to very far away from the instrument, in order to save the thermocouple material, reduce costs K-type thermocouple wholesale, usually compensated thermocouple wire The cold end (free end) extends to control indoor temperature is relatively stable, the terminal is connected to the meter. It must be noted, the role of thermocouple wire extends only from the main hot electrode K-type thermocouple, so the cold end of the thermocouple to the control room instrumentation mobile terminals, which in itself does not eliminate the effect of temperature on the cold side temperature of K-type thermocouple, can not afford compensation. Therefore, the need to use other correction methods to compensate for the cold junction temperature effect on the temperature of t0 ≠ 0 ℃ time. When using the thermocouple wire must be noted that the model match, can not pick the wrong polarity, the difference between the compensation and thermocouple wire connecting terminal temperature should not exceed 100 ℃. K-type thermocouple type K thermocouple Shandong Main _ _ 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!
