RTD vs PT100 Resistance Sensor Temperature Measurement Probe

RTD vs PT100: Sensor Resistance in Temperature Measurement Probe

The main difference between an RTD and a Pt100 is the material used for the sensing element: PT100 is a specific type of RTD thermal resistor, and its name comes fromPlatinum” (platinum) и “100” (100 Охмс на 0 ° Ц). It is the most commonly used RTD sensor and is widely used in industrial process control, laboratory measurement and other fields that require high-precision temperature monitoring. The advantages of PT100 include:

Temperature acquisition of 4-wire PT100 temperature sensor

Актуелна куповина 2, 3, и 4-жичани сензори на температури ПТ100

A PT100 sensor acquires temperature by measuring the change in its electrical resistance, which directly correlates to the temperature it is exposed to; as the temperature increases, the resistance of the platinum element within the sensor also increases, allowing for a precise calculation of the temperature based on this resistance change; essentially, the “100” in PT100 signifies that the sensor has a resistance of 100 Охмс на 0 ° Ц, and this value changes predictably with temperature fluctuations.
