Rosemount Temperature Transmitter

A temperature transmitter is an electrical instrument that interfaces a temperature gauge – such as a thermocouple, RTD, or thermistor – to a measurement or control device, such as a PLC, DCS, PC, loop controller, data logger, display or recorder.

Typically, temperature transmitters isolate, amplify, filter noise, linearize, and convert the input signal from the sensor then send (transmit) a standardized output signal to the control device. Common electrical output signals used in manufacturing plants are 4-20mA or 0-10V DC ranges. For example, 4mA could represent 0°C and 20mA means 100°C.
