Thermistors PTC adalah perintang dengan pekali suhu positif, yang bermaksud bahawa rintangan meningkat dengan peningkatan suhu. Thermistor PTC dibahagikan kepada dua kumpulan berdasarkan bahan yang digunakan, struktur mereka, dan proses pembuatan.

PT100, the full name of platinum thermal resistor, is a resistive temperature sensor made of platinum (Pt), and its resistance value changes with temperature. The 100 after PT means that its resistance value is 100 ohms at 0℃, and its resistance value is about 138.5 ohms at 100℃.

This article explores 2-, 3-, and 4-wire configurations for resistance temperature detectors (RTS), focusing on how environmental factors, keperluan ketepatan, cost, and wire configuration affect selection. The 4-wire configuration is complex but offers the highest accuracy, while the 2-wire configuration has advantages in lower-accuracy applications. Choosing a configuration requires a combination of application requirements and practical conditions.
