The Rosemount 848T wireless temperature transmitter for high density temperature measurement includes a new EDD (Electronic Device Display) user interface that provides simple, graphical screens to deliver important configuration details and other information. Mounting and sensor connection hardware also exhibit the ease-of-use. The wireless transmitter monitors up to four independently configurable RTD, thermocouple, ohm, millivolt and 4–20mA inputs, allowing users access to more of these important temperature measurements. The resulting increased visibility to plant operations allows for proactive maintenance and monitoring of key assets. These include motor bearings that drive pumps, fans and compressors, as well as heat exchangers, tanks, reactors and boilers. The device is selfpowered and utilises SmartPower technology to provide an intrinsically safe power module with long battery life. Not only are installation costs minimised by eliminating the signal wiring, but the sensor wiring costs are reduced by being able to mount the device closer to the process.
