Intelligent Interface Unit (IIU)

The intelligent interface unit (IIU) integrates corrosion-monitoring transmitters with either a supervisory control and data acquisition (SCADA) system or distributed control system (DCS) through Modbus or object linking and embedding for process control (OLE for Process Control. or OPC). It operates inexpensively, and works with the manufacturer’s Microcor, Quicksand and Corrater corrosion-monitoring transmitters. It reads real-time corrosion rates, erosion rates, and pitting tendency in water systems. Designed for smaller-scale corrosion-management systems, the unit can also be used as a building block of a full corrosion-management system with sophisticated software for complete corrosion control. It increases efficiency by eliminating the manpower needed to manually read probes and instruments. The unit can communicate with transmitters by means of hard-wired connections, fiberoptic links, and Ethernet links, among others.
