What Is A PT1000 Temperature Sensor?

Pt1000 sensors are the second most common type of platinum resistance thermometer. Often resistance thermometers are generally called Pt1000 sensors, even though in reality they may not be the Pt1000 type. Pt refers to that the sensor is made from Platinum (Pt). 1000 refers to that at 0°C sensor has a resistance of 1000 ohms (Ω). Pt1000 sensors are used over Pt100 sensors in two wire applications as Pt1000s make lead resistance less significant.
