Multi-point thermocouple distribution | power meter multi-point thermocouple measured since | Hunan multi-point thermocouple measured the force provided by the Shanghai Automation Instrumentation Co., Ltd.. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is specialized in "industrial thermocouple, RTD, compensation wire, hot wire" of the enterprise, the company of "honesty, hard service" concept, to provide you with The most high-quality products and services. Welcome to inquire! Contact: China powder. Thermal response time measurement method more complex, different test conditions have different measurements, because it is affected by the rate of heat exchange with the surrounding medium influence the thermocouple, heat transfer rate, the thermal response time is short. In order to make the thermal response time thermocouple products comparable national standards: thermal response time should be carried out on a dedicated flow test device. Flow rate of the device should be maintained 0.4 ± 0.05m / s multi-point thermocouple, the initial temperature in the range of 5-45 ℃, the temperature step is 40-50 ℃. During the test, the main multi-point thermocouple, the water temperature should not exceed the temperature of the step change in the value of ± 1%. Subjects thermocouple into a depth of 150mm or design into the depth (the smaller the value selected and noted in the test report). 2, the intermediate conductor law access intermediate conductor (third conductor) wholesale multi-point thermocouple in the thermocouple circuit, 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, which is intermediate conductor law. 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 of multi-point thermocouple prices, 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!
