Temperature Sensors & Transmitters
Temperature sensors and transmitters allow the monitoring, control, and even the measurement of temperature. At their most basic, these sensors and transmitters comprise two elements: a temperature-measuring device (the sensor part), which is the part that does the "sensing"; and a signal-processing component (the transmitter part), which converts the kind of signal generated by the "sensing" into a format that can be displayed or further processed.
Resistance temperature detectors (RTDs) and thermocouples are two of the most popular temperature-sensing technologies. As their name suggests, RTDs measure temperature by detecting changes in electrical resistance. In the case of an RTD that uses platinum, the resistance change is highly linear with temperature.
Taking a signal from a temperature sensor and converting it into a standardized output is the job of temperature transmitters. Transmitters can be used with either thermocouples or RTDs, but using them with RTDs seems to be becoming more common.
