A Wireless Solution for High Density Temperature Measurement 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.
- Innovative temperature measurement for high density applications that provide installation and operational savings
- Independently configuratble inputs that support RTD, thermocouple, ohm, mV, and 4-20 mA signals
- Enclosure options and intrinsically safe design allows for installation close to any process, including hazrdous areas
- Interfaces with any host using a 3420 Fieldbus Interface Module or Smart Wireless Gateway
- WirelessHART capabilities extends the full benefits of PlantWeb to previously inaccessible locations

Ambient Temperature Compensation
Ambient temperature fluctuations are commonly encountered in industrial process environments. Individually characterized transmitters compensate for these fluctuations resulting in improved measurement accuracy and stability. This reduction in variability allows the process to be operated closer to the set point, resulting in greater throughput. |
