PT100 temperature sensors, also known as RTD (Resistance Temperature Detector) sensors, are widely used for high-accuracy and stable temperature measurement in industrial and hygienic process applications. The PT100 sensor operates on the principle that the electrical resistance of platinum changes predictably with temperature, providing precise and repeatable readings.

A PT100 sensor has a resistance of 100 ohms at 0°C, making it a globally accepted standard for accurate temperature monitoring. Due to their excellent accuracy, long-term stability, and reliability, PT100 sensors are preferred over thermocouples in applications where precision and consistency are critical.

These sensors are commonly used in food, dairy, beverage, pharmaceutical, chemical, HVAC, power, and industrial process systems.
