✸ Temperature transmitter is a device that connects to a temperature sensor to transmit the signal elsewhere for monitoring and control purposes. 

✸The transmitted temperature signal can be scaled inside the temperature transmitter to accommodate the needs of the application, e.g. the 4mA can be used to represent -17.7°C (0° Fahrenheit) and the highest value in the range (20mA) can be used to represent 37.7° C (100° Fahrenheit)
