How to Choose the Right High-Accuracy Temperature Sensor: PT100, Thermocouple, or NTC?
Selecting the appropriate temperature sensor is crucial for achieving accurate and reliable measurements in various applications. Three commonly used sensors are PT100, thermocouples (specifically Type K), and NTC thermistors. Each has distinct characteristics that make them suitable for specific scenarios. PT100 Sensors PT100 sensors are a type of Resistance Temperature Detector (RTD) known for their high accuracy and stability. They operate on the principle that the electrical resistance of platinum changes predictably with temperature. A PT100 sensor has a resistance of 100 ohms at 0°C. These sensors are suitable for applications requiring precise measurements over a temperature range of -200°C
