What does RTD mean?

RTD is a sensor that sometimes measures temperature by correlating the resistance of the RTD element with temperature. RTD are sometimes referred to generally as a resistance thermometer. Most of RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core.  The relationship between as RTD resistance and this surrounding temperature is highly predictable, allowing for accurate and consistent the resulting voltages drop across the resistor, the RTD resistance can be calculated and the temperature can be determined.
