When the two thermocouple wire thermocouple material composition determine the size of the thermocouple thermoelectric power, only concerned with the thermocouple temperature difference; if the thermocouple cold junction temperature is kept constant, this thermocouple thermoelectric power into only the working end single-valued function of temperature. A conductor or semiconductor and B of two different materials welded together, form a closed loop, as shown in FIG. When the two attachment points when the temperature difference between 1 and 2, it generates an electromotive force between the two conductors A and B, thereby forming a current in the circuit size. Thermocouple is to use this effect to work. In theory, any two different conductor (or semiconductor) can be formulated as a thermocouple, but as a practical Elbow thermocouple temperature measurement devices specifications required of it in many ways. Engineering and technology in order to ensure the reliability of the main right-angle bend thermocouple, and sufficient measurement accuracy, not all materials can be composed of a thermocouple, thermocouple generally right angle bend thermocouple electrode material, the basic requirements are: 1 within the temperature range, thermal stability, does not change over time Elbow thermocouple prices, there is sufficient physical and chemical stability, easy to oxidation or corrosion; 2, small temperature coefficient of resistance, high conductivity, low specific heat; 3. The temperature in the thermoelectric power generation should be large, and the thermoelectric power between temperature and linear or nearly linear relationship between single-valued function; 4, material copied resistance, high mechanical strength, simple manufacturing process, and cheaper prices. Elbow Elbow thermocouple thermocouple specifications _ _ force since the instrument thermocouple measuring the force measured by 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!
