High Accuracy and Reliability for Monitoring Applications
The Rosemount 648 temperature transmitter is ideal for monitoring applications, especially in hard-to-reach or cost-prohibitivelocations. It provides reliability with advanced accuracy for all installations. The Rosemount 648 can be configured for a variety of sensor inputs: RTD, thermocouple, millivolt, or ohm.

SELF-ORGANIZING NETWORKS
Self-forming, intelligent devices that provide exceptional data reliability and network stability. The Rosemount 648 works the same as wired devices, allowing you to leverage existingpractices, training and maintenance procedures, but without the added wiring costs.

TRANSMITTER-SENSOR MATCHING
Entering the temperature-resistance profile specific to the RTD sensor into the 648 transmitter results in transmitter-sensor matching. This eliminates the sensor interchangeability error, which can improve accuracy.

INTEGRAL LCD DISPLAY
Local indication of temperature measurementand diagnostics provides real time and accurate verification of process conditions.

LAYERED SECURITY KEEPS YOUR NETWORK SAFE
Emerson Process Management’s layered approach to wireless network security ensures that your network stays protected. The network devices implement Encryption, Authentication, Verification, Anti-Jamming and Key Management methods to ensure that data transmissions arereceived only by the Wireless Gateway.

RELIABLE TRANSMITTER PERFORMANCE
The 648 ensures top transmitter performance in harsh and/or noisy EMI/RFI environments.

SMARTPOWER™
Rosemount devices incorporate SmartPower™ refers to the benefits that users enjoy due to the engineering efforts made to reduce power consumption. Emerson has power-optimized our instrumentation, both hardware andsoftware, to extend power module life while still delivering highly reliable measurements with rich HART data and diagnostic information. SmartPower™.

DIGITAL FIELD DEVICES THAT POWER PLANTWEB
The Rosemount 648 powers PlantWeb® by communicating important temperature diagnostics and PlantWeb alerts to ensure process health and enable economical single-sensor architecture.

MOUNTING FLEXIBILITYPlantWeb head mount transmitters to be direct mounted via a sensor or thermocouple, or remote mounted, allowing the flexibility needed to reach any measurement point. The PlantWeb head also offers an LCD for local display that is easily visible, even in remote mount installations.
