PTC thermistors are resistors with a positive temperature coefficient, which means that the resistance increases with increasing temperature. PTC thermistors are divided into two groups based on the materials used, their structure, and the manufacturing process.
The Pt100 Sensor probe has a resistance of 100 ohms at 0 °C and 138.5 ohms at 100 °C. Its resistance varies linearly with temperature, i.e., as temperature increases, so does the resistance of the Pt100; therefore, if we can measure resistance, we can determine temperature.
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 (RTDs), 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.
