Rosemount 644 provides measurement accuracy in a compact head-mount design. The company added Foun- dation Fieldbus communications to the temperature transmitter, which powers the company's PlantWeb digital plant architecture. The transmitter delivers process-variable as well as sensor- and transmitter-diagnostic information to increase process efficiency. Immediate indication of sensor and transmitter health is provided by an integral LCD display and on an AMS screen.
