Thermocouple is actually an energy converter that will convert heat to electricity produced by thermoelectric potential measured temperature, for thermocouple type K thermocouple thermoelectric power sales, should pay attention to the following questions: 1, thermocouple thermoelectric power is the difference between the two ends of the working end of the thermocouple function of temperature, rather than the thermocouple cold junction and the working end, a function of the temperature difference between both ends; 2, thermoelectric power generated by the thermocouple size, when the material is a thermocouple When homogeneous, with the length and diameter of the thermocouple irrelevant, only the temperature difference across the thermocouple materials and components related to; the thermocouple materials are generally more expensive (in particular, the use of noble metal), and the distance measurement points to the instrument very far, in order to save the thermocouple material, reduce costs, usually compensation wire thermocouple cold end (free end) extends to control indoor temperature is relatively stable K-type thermocouple, connected to the meter terminals. It must be noted, the role of thermocouple extension wire from the hot electrode only K-type thermocouple prices, thermocouple cold end to move to the control room instrumentation terminals, which in itself does not eliminate the influence of temperature on the cold side temperature measurement, 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 measuring wholesale _ force since the instrument type thermocouple type K thermocouple _K force measured by Shanghai Automation Instrumentation Co., Ltd .. Shanghai Automation Instrumentation Co., force measurement (www.licesh.com) is the Shanghai Zhabei District, flow meters leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Since the force measuring device leadership with the staff warmly welcome all inquiries negotiations to create the force measuring instrument since a better future.
