A Pt100 sensor is a type of RTD (Resistance Temperature Detector) that uses platinum to measure temperature. The “100” refers to the sensor having a resistance of 100 ohms at 0°C. Pt100 sensors are highly accurate, stable, and provide a linear response over a broad temperature range, making them ideal for precise temperature measurements in industrial and laboratory settings. They are widely used due to their reliability and consistency in converting temperature changes into electrical signals.
