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.
Probe sensor pt100 mempunyai rintangan 100 ohm di 0 ° C dan 138.5 ohm di 100 ° C.. Rintangannya berbeza secara linear dengan suhu, I.e., apabila suhu meningkat, Begitu juga rintangan PT100; oleh itu, Sekiranya kita dapat mengukur rintangan, kita dapat menentukan suhu.
The main difference between a Pt100 and a Pt1000 sensor is their nominal resistance at 0°C, with a Pt100 having a resistance of 100 ohms and a Pt1000 having a resistance of 1000 ohms, meaning the Pt1000 has a significantly higher resistance, making it more suitable for applications where precise temperature measurement is needed with minimal influence from lead wire resistance, especially in 2-wire circuit configurations;
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, accuracy requirements, 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.
An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time.
