Description
The PT100 RTD is a high-precision temperature sensor that plays a key role in many industrial applications. Its design is based on a fine platinum wire whose electrical resistance depends on temperature. At 0 degrees Celsius, this sensor has a resistance of exactly 100 ohms, which gives it its name.
The PT100 RTD operates on the principle that the resistance of a metal increases with increasing temperature. This property makes the PT100 particularly suitable for precise temperature measurements. Unlike other temperature sensors, such as thermocouples, the PT100 RTD offers excellent linearity and very low drift over time, making it a reliable choice for many industrial applications.
Another advantage of the PT100 RTD is its high accuracy. In critical applications, such as the chemical or pharmaceutical industries, it is crucial to measure precise temperatures to ensure product quality. The PT100 can measure temperatures in a range from -200 to +850 degrees Celsius, making it versatile.
The installation and calibration of the PT100 RTD is relatively simple. It is often used in conjunction with special measuring devices that precisely convert resistance changes into temperature values. This allows for easy integration into existing process monitoring systems.
