RTD Temperature Sensors

RTDs are a resistor temperature sensor which change resistance with temperature changes.  The most common RTDs are made from platinum elements which have a base resistance of 100 ohms at 25°C and are often referred to as PT100 sensors.  RTDs provide high accuracy and broad temperature range.  Since the resistor element is resistant to the affects of electrical noise, they work well in industrial environments.
