Emerson's Smart Wireless network using the Wirelesshart communications standard is contributing to process improvements at the Calgon Carbon plant in Blue Lake, California. The network provides continuous temperature measurements from a rotating catalyst kiln, where spent carbon particles are reactivated. Six Rosemount wireless temperature transmitters were installed to monitor temperatures in the kiln and transmit a steady stream of data, giving operators more information for controlling heat levels in each zone.The wireless transmitters mounted on raised platforms on the surface of the kiln were connected to the existing thermocouples and the Wirelesshart self-organising mesh network was set up with a single Smart Wireless gateway. The six transmitters monitor temperatures in five zones of the kiln and at the outlet, communicating data reliably from the rotating kiln to the gateway, which then integrates the measurements in a host PLC.
Emerson offers a range of wireless field-instrumentation and plant-operations equipment, including Fisher position monitors, Rosemount Analytical and Machinery Health Management devices, and native wireless interfaces to AMS Suite predictive maintenance software, DeltaV digital-automation systems and Smartstart services.
