Temperature Transmitter

DESCRIPTION:

A temperature transmitter is a device that connects to a temperature sensor to transmit the signal elsewhere for monitoring and control purposes. Typically, the temperature sensor is either an RTD, Thermisor or Thermocouple type sensor and will interface with a PLC, DCS, data logger or display hardware.

4-20ma temperature transmitters are common in manufacturing as the majority of industrial equipment communiciates via this signal range. 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)
