थर्मल रेजिस्टर्स के कार्य करने के सिद्धांत, दो-तार और तीन-तार प्रणालियों के बीच का अंतर, थर्मल रेजिस्टर्स की गुणवत्ता का मूल्यांकन करना, और उपकरण के वास्तविक संचालन के दौरान उत्पन्न होने वाली समस्याओं का विश्लेषण और प्रसंस्करण करते हुए, माप की सटीकता प्राप्त की जाती है, और रखरखाव कर्मियों को उपकरण की संचालन स्थिति को समझने के लिए मार्गदर्शित किया जाता है।

थर्मल रेजिस्टर्स का अवलोकन

Thermal resistors are a type of sensor that detects temperature and are often used in medium and low temperature areas. Since metal conductors have the characteristic that resistance changes with temperature, thermal resistors use this characteristic as their operating principle. In addition, thermal resistors have the characteristics of high measurement accuracy and stable performance. Through practical comparison, platinum thermal resistors can currently achieve measurement accuracy, so platinum thermal resistors are often selected for detection in industrial temperature measurement. Usually, the manufacturing materials of thermal resistors are mostly pure metals, among which platinum and copper are the most widely used metal materials. In addition, metal materials such as nickel, manganese and rhodium are gradually becoming popular choices for manufacturing thermal resistors. Similarly, the commonly used temperature sensing material in metal thermal resistors is platinum wire. In industrial measurements, temperature sensing materials such as iron, copper, nickel, and iron-nickel are also selected as substitutes. At present, most of the thermal resistors are PT100 types.
