Talk about the thermal resistance temperature measurement principle and production materials

by:JVTIA     2022-03-24
Thermal resistance is one of the most commonly used temperature detectors in medium and low temperature areas. The main advantages of thermal resistance are high measurement accuracy and stable performance. Among them, platinum thermal resistance has undoubtedly the highest measurement accuracy. It is widely used in temperature measurement and occupies a large proportion. At the same time, it is also made into a standard temperature measurement and calibration instrument, which is the RTD often mentioned in various literatures. Thermal resistance temperature measurement principle and manufacturing materials: due to thermal resistance The temperature measurement is based on the characteristic that the resistance value of the metal conductor increases with the increase of temperature. Thermal resistances are generally made of pure metal materials. At present, platinum and copper are the most widely used metals. In addition, thermal resistances have been gradually made of materials such as tin, rhodium, nickel and manganese. So when the thermal resistance is wired, is there any difference between different wiring methods? Next, I will briefly introduce the difference between two-wire, three-wire, and four-wire thermal resistances: From the temperature measurement principle of thermal resistance, it can be known that the change of the measured temperature is directly measured by the change of the resistance value of the thermal resistance. Therefore, the thermal resistance Changes in the resistance of the various lead wires will affect the temperature measurement. In order to eliminate the influence of lead resistance, a three-wire or four-wire system is generally used. The thermal resistance wiring is different, mainly related to the application. Ordinary 2-wire is used for close distance measurement; 3-wire is used for long-distance measurement, mainly to restrain the influence of line resistance and interference. The other 4-wire thermal resistance is proposed for higher precision measurement. The application is mainly to apply a current to the thermal resistance, and then measure its voltage to improve the measurement accuracy and flexibility. The detection equipment (temperature control meter, PLC input, etc.) connected with the thermal resistance has four terminals.
is a must have for anyone who appreciates RTD supplier to the greatest extent.
