PTC termistori ir rezistori ar pozitīvu temperatūras koeficientu, kas nozīmē, ka pretestība palielinās, paaugstinoties temperatūrai. PTC termistori ir sadalīti divās grupās, pamatojoties uz izmantotajiem materiāliem, to struktūra, un ražošanas process.

PT100, the full name of platinum thermal resistor, is a resistive temperature sensor made of platinum (Pt), and its resistance value changes with temperature. Līdz 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, precizitātes prasības, 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.
