Yokogawa has signed a sales agreement with Rohrback Cosasco Systems, a US-based manufacturer of corrosion monitoring systems to distribute the Cosasco ISA100 wireless-based MWT-3905 and CWT-9020 corrosion monitors: also Cosasco will distribute the Yokogawa ISA field wireless system devices. Yokogawa systems operating to ISA100.11a-2011 include an application layer with process control industry standard objects, device descriptions and capabilities, a gateway interface, infrared provisioning, and a backbone router.
Yokogawa therefore has now added corrosion sensors to its line-up of field wireless devices that help customers efficiently maintain facilities and ensure safety at their plants. For Cosasco, the ability to offer its corrosion monitors in combination with Yokogawa field wireless devices is expected to increase sales.
With a field wireless system, plant field devices and analysers are able to communicate wirelessly with host-level monitoring and control systems. The rising need to improve productivity and enhance safety by collecting more data on plant operations is driving the demand for field wireless devices, which can be installed even in difficult to access locations. Field wireless devices have the added advantage of reducing installation costs.
Yokogawa has developed ISA100 Wireless-based technologies and products such as wireless access points and management stations, and Cosasco has a long global track record in supplying various kinds of corrosion monitors to the oil and gas, petrochemical, chemical, and other industries. Through this agreement, Yokogawa aims to increase sales for its field wireless business by being able to offer a wider field wireless device lineup.
Cosasco Wireless Corrosion Monitors
Corrosion sensors monitor the thinning or deterioration of the metal walls of pipes and other installations. A variety of technologies are employed, including electrical resistance and ultrasonics. The Cosasco MWT-3905 and CWT-9020, the devices covered by this sales agreement, are direct measuring type corrosion sensors that use high speed electrical resistance and linear polarisation resistance (LPR) technology. This enables corrosion rate measurement at a low installed cost in all process environments, including hazardous areas. The units are particularly applied for the monitoring of corrosion in facilities at offshore platforms and other types of oil and gas installations, plus petrochemical plants, chemical plants, and water and sewage treatment plants.
Rohrback Cosasco is a part of Halma plc, a UK conglomerate.
