Description:

The Rosemount 848T Foundation Fieldbus Temperature Transmitter simplifies and reduces the cost of a plant's process control architecture. It replaces traditional temperature monitoring methods (wired direct, low cost single input transmitters, and multiplexers) with an intrinsically safe, eight input transmitter that mounts close to the process. The industry first Measurement Validation Diagnostic available on the Rosemount 848T Fieldbus transmitter provides insight into your process and can identify measurement abnormalities before they become a major issue, saving your time and money associated with process shutdowns and helping you run your process more efficiently. The 848T also comes with a new Device Dashboard, which gives users a clear view of everything needed to evaluate, diagnose, and configure the 848T. The new interface leverages Human Centered Design principles to create a streamlined, easy and efficient user experience, eliminating the complexities, and allowing the user to realize the benefits of FOUNDATION fieldbus.

Applications:

Many users across the process industry need to monitor hundreds to thousands of temperature measurements in a plant to ensure efficient operations. The 848T Wireless monitors up to four independently configurable RTD, thermocouple, ohm, millivolt and 4 – 20 mA inputs allowing users access to more temperature measurements without any signal wire. Increased visibility to plant operations allows for proactive maintenance and monitoring of key assets such as motor bearings that drive pumps, fans and compressors, as well as heat exchangers, tanks, reactors and boilers.

Fully compatible with any WirelessHART™ network, the Rosemount 848T Wireless provides the same rich diagnostic data and reliable performance as other devices in the Smart Wireless family. It monitors many temperature measurements with one device ensuring accurate and stable measurements and continuously monitors measurement integrity. The device is self-powered and utilizes SmartPower™ to provide an intrinsically safe power module with long battery life.
