Wireless temperature monitoring

Emerson Process Management Australia has expanded its Smart Wireless solutions with the introduction of its Rosemount 848T wireless temperature transmitter for high-density temperature measurement. The 848T’s four-channel efficiency adds to installation cost savings of Smart Wireless technology to reduce per point costs and thereby deliver more measurement data for use in improving operations and maintenance.

The 848T embodies significant investment by Emerson in ease of use. The 848T includes an EDD (electronic device display) user interface that provides simple, graphical screens to deliver important configurations and information. Mounting and sensor connection hardware also exhibits ease of use.

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 transmitter monitors up to four independently configurable RTD, thermocouple, ohm, millivolt and 4-20 mA 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.

Fully compatible with any WirelessHART network, the Rosemount 848T 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 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.
