Rosemount 644 Measurement Converters for Precise Signal Measurements

Rosemount 644 transmitters are designed to measure and convert signals from primary measurement transducers (thermal resistance transducers, thermoelectric transducers, and transducers with an output signal in the form of a change in electrical resistance or electrical DC voltage) into a unified output signal of electrical DC current in the range from 4 to 20 mA and/or a digital signal for transmission over a wired HART interface, or into a digital signal
