2, the intermediate conductor law access intermediate conductor (third conductor) standard thermocouple manufacturers, as long as the temperature is the same at both ends of the intermediate conductor, the introduction of the intermediate conductor of the thermocouple circuit has no effect on the total potential of the standard thermocouple in the thermocouple circuit, which is intermediate conductor laws. Application: According to the law of the middle conductor, in actual thermocouple temperature applications, often using the hot end of the welding, cold end of the open form, the cold side of the display instrument via the connecting wires connected to form measurement system. Some people worry that the connection with copper wire thermocouple cold end to the meter reading mV value, contact potential at the junction of the thermocouple wire and produced measurements will produce additional errors. According to this law, there is no such error! 4 standard thermocouple distribution, this law is the law of the reference electrode only research professionals, concerned about the standard thermocouple pictures, general production, who use the links do not understand the explanation is simple: use of high purity platinum wire as the standard electrode, assuming nickel chromium - nickel silicon thermocouple positive and negative, respectively, and the standard electrode pair, their sum is equal to the value of this nickel-chromium - nickel silicon value. Standard thermocouple production | Jiangsu standard thermocouple | force measurement since the instrument class quality measured by the Shanghai Automation Instrumentation Co., Ltd ..
