A transmitter is an electronic device that is generally mounted in the field in close proximity to a sensor. The sensor (also known as a transducer) measures a physical variable such as temperature or pressure and OUTPUTS a very low level electronic signal. The basic FUNCTION of the transmitter is to provide the correct electrical power to turn on (or excite) the sensor then to read the low level sensor signal, amplify it to a higher level electrical signal and send that signal a long distance to a control or read-out device.

SINCE low-level electrical signals do not transmit long distances with great accuracy, installing a transmitter generally gives a TREMENDOUS improvement in the accuracy of the information delivered to a larger control system. Typically the output form the transmitter is 4-20 mA or 0-10 V
