RTD - or Resistance Temperature Detectors - is a temperature sensor that contain a resistor that changes resistance value as its temperature changes. They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability. Thin film Platinum Resistance Temperature Detectors from TT-PT group are very commonly used components in industrial applications thanks to very high precision and long-term stability, Capital Semiconductors Temperature Sensors offers three standard types of PT RTDs: pt500, PT500 and pt5000, that can be provided in standard tolerance classes.
PT500 sensors are a rare type of platinum resistance thermometer. Pt refers to that the sensor is made from Platinum (Pt). 500 refers to that at 0°C sensor has a resistance of 500 ohms (Ω).
