Industrial RTD Pt100 Temperature Sensor

An RTD (Resistance Temperature Detector) temperature sensor measures temperature by using a metal element whose electrical resistance changes predictably with temperature. The element is usually made of platinum, nickel, or copper, and this resistance variation allows for accurate and stable temperature measurement over a wide range.

A PT100 temperature sensor works by measuring the change in electrical resistance of a platinum element as the temperature changes. The “100” refers to the sensor having a resistance of 100 ohms at 0°C. As the temperature increases, the resistance of the platinum increases in a precise and predictable way, allowing the sensor to accurately determine temperature.

To use an RTD temperature sensor, connect it to a compatible measuring device or transmitter that can read resistance and convert it to temperature. Place the sensor where accurate temperature measurement is needed, ensuring good contact with the surface or medium being measured. The device then sends the temperature signal to a display or control system for monitoring or process control.
