A homogeneous conductor by law (conductor or semiconductor) material welded at both ends with a homogeneous composition closed loop, regardless of how the conductor cross-section and the temperature distribution, will not produce standard thermocouple contact potential distribution, thermoelectric power offset, loop The total potential of zero. Visible image standard thermocouple, thermocouple must consist of two distinct homogeneous conductor or semiconductor. If the hot electrode material is uneven, due to the temperature gradient exists, it will generate additional thermoelectric power. 3 standard thermocouple manufacturers, law intermediate temperature thermocouple circuit two contacts (temperature T, T0) between the thermoelectric power, equal to the thermocouple temperature T, the thermoelectric power and when the temperature Tn Tn, T0 when the thermoelectric power algebra and. Tn said intermediate temperature. Application: As is usually non-linear relationship between the thermocouple ET, when the cold junction temperature is not 0 degrees Celsius, not the actual use of the known circuit thermoelectric potential E (t standard thermocouple, t0) to strike a direct look-up table hot end temperature ; it can not take advantage of the known circuit practical thermoelectric potential E (t, t0) to strike a direct look-up table of temperature values, coupled with the hot end of the cold junction temperature to determine the value of the measured temperature, adjustment shall be corrected intermediate temperatures law. Beginners often do not follow the law to amend the standard intermediate temperature thermocouple sales |! Standard thermocouple | force measuring instrument class quality since the force provided by the Shanghai Automation Instrumentation Co. measured. 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!
