Temperature sensing is an essential aspect of many industrial and scientific processes. Accurate temperature measurement can help maintain quality, improve efficiency, and ensure safety in various applications. Among the various types of temperature sensors, the PT100 is a popular and reliable choice. In this article, we will introduce the pt100 temperature sensor, its properties, and applications.

What is a PT100 Temperature Sensor?

A PT100 temperature sensor is a type of resistance temperature detector (RTD) that measures temperature based on the change in resistance of a platinum wire. The "PT" in PT100 stands for platinum, and "100" refers to the nominal resistance of the sensor at 0°C (32°F), which is 100 ohms. The PT100 sensor is one of the most accurate temperature sensors available and is widely used in industrial and scientific applications.
