Temperature transmitters are used to convert relatively weak thermocouple or RTD output into a stronger analog (4-20mA or HART) or digital (Profibus or Fieldbus) signal output. The Transmitter acts as a bridge between the temperature sensor and the control device. By using a transmitter you can avoid long runs of expensive thermocouple wire and you can extend the distance the signal can be sent.
