Wireless transmitter provides high resolution wireless corrosion monitoring
May 4, 2009
The wireless transmitter has undergone extensive development and testing and is now available with hazardous area certification. The wireless corrosion transmitter offers many new benefits for corrosion monitoring. Each wireless corrosion transmitter will work as a node in a self-organizing network (mesh) to ensure consistent delivery of data. Unlike many approaches to in-plant wireless systems, which require direct line-of-sight between the instrument and the communications gateway, the RCS approach ensures network integrity by allowing wireless transmitters to communicate with each other. Every wireless transmitter serves as a network connector ensuring there can be no single point of failure. In the event a temporary obstruction blocks a direct connection, the network automatically reroutes the signal to an adjacent device, ensuring network reliability and data integrity. The Microcor Wireless Transmitter (MWT) uses high-resolution metal loss measurement that provides 18-bit resolution, and is rated for operation in hazardous locations. It is designed to perform well in both arctic and desert conditions; the MWT has an allowable operating range of from -40°C to 70°C. The wireless corrosion transmitter will provide accurate and reliable corrosion rates in any process media at speeds approaching real time. Correlating real time corrosion rates with other process parameters enables facility operators to realize process control related to variables such as chemical inhibitor feed. Chemical inhibitor costs can be reduced without compromising plant safety, maximizing the return on investment in the corrosion monitoring system. The wireless transmitter provides alerts to system upsets, lengthens the time between plant shutdowns, extends overall asset life, and ensures fast reaction to environmental mishaps or equipment failures caused by corrosion.
