Rohrback Cosasco Systems, Inc. Microcor Wireless Transmitter (MWT) Features: Highly Secure and Reliable Self Organizing Wireless Mesh Network High Resolution Metal Loss Measurement for all process environments Low installed cost International Hazardous Area Certifications WirelessHART 7 protocol Seamlessly Integrates with Emerson Smart Wireless Networks The MWT transmitter is based on RCS s Microcor high resolution corrosion measurement technology, the industries most widely used and only technology capable of operating in any process environment. The 2.4 GHz self-organizing wireless network delivers exceptional data reliability and network stability through its high security communication. Microcor online systems are already known worldwide for their proven accuracy and reliability. The wireless link now adds simplicity, flexibility, and exceptional economy of installation to new or existing installations. The MWT can be supplied as part of a complete corrosion management system comprising access fittings, probes, MWT s, gateway, corrosion management and process interface software. Alternatively, the MWT can be added seamlessly to an Emerson Smart Wireless Network or via direct input from the gateway through Modbus Interface to virtually any Process Automation System. MWT S are quickly and easily installed without the time and expense required for wiring. Once installed metal loss and computed corrosion rate is read from the Gateway directly into your DCS system, an RCS ICMS3-Amulet Corrosion Management System, or a Microcor Tools software package for smaller scale systems. MWT s are easily configured using a direct connection to a PC or laptop in a safe area, or through RCS s handheld instrument in hazardous locations. The MWT uses high resolution metal loss measurement providing 18 bit resolution, and is rated for operation in hazardous locations (Class I, Zone 1). The allowable operating range of from -4 C to 7 C is proven every day by existing systems reliably working in the harsh environments of the frigid arctic and deserts of the Middle East. The MWT power module has a typical life of 3 years and is hazardous location certified to allow change out in the hazardous area. Typical wireless range is 9 ft (3 m) in medium density plant environments from transmitter to transmitter or transmitter to gateway, with up to three hops permissible from any transmitter back to its gateway. Other wireless communication options may be permissible. For details, contact RCS.
Wireless Overview Microcor Wireless Transmitters The MWTs communicate with each other through a self-organizing 2.4 GHz mesh network, ensuring no point of failure. Gateway The gateway serves as a connection between the MWTs and a host system. The gateway is easily configurable and integrates into a designated control system through serial or ethernet connections.
