Differences Between Pt100 and Pt1000 Sensors

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;

What is the Difference Between 2-, 3-, and 4-Wire RTD Sensors?

This article explores 2-, 3-, and 4-wire configurations for resistance temperature detectors (РТС), 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.
