Yokogawa and Cosasco conclude agreement for sale of wireless products

May 2017 Industrial Wireless

Yokogawa Electric Corporation has announced that it has signed a mutual sales agreement with Rohrback Cosasco Systems, a leading US-based manufacturer of corrosion monitoring systems and equipment. Under this agreement, Yokogawa will distribute Cosasco’s ISA wireless-based MWT-3905 and CWT-9020 corrosion monitors, and Cosasco will distribute Yokogawa ISA wireless-based field wireless system devices.

Thanks to this agreement, Yokogawa can add 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.

Overview of the tie-up and its objectives

With a field wireless system, plant field devices and analysers are able to communicate wirelessly with host-level monitoring and control systems. The increasing 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, on the other hand, aims to drive up sales for its wireless corrosion monitors by being able to offer them in combination with Yokogawa field wireless devices that are used to link field devices with host systems.

Features of Cosasco’s 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. Cosasco’s 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. The major features are as follows:

• Corrosion rate measurement for all process environments.

• Highly secure and reliable ISA100 Wireless networks.

• Low installed cost.

• International hazardous area certifications.

Applications include monitoring of corrosion in facilities at offshore platforms and other types of oil and gas installations, petrochemical plants, chemical plants, and water and sewage treatment facilities.

Yokogawa’s approach to field wireless communications

Yokogawa released its first ISA100 wireless system devices and wireless pressure and temperature transmitters in July 2010. In addition to enabling sophisticated control techniques in continuous processes, this gave customers a wider range of devices to choose from.

Yokogawa will continue to expand its line-up of ISA100 wireless transmitters and other devices such as adaptors to develop best-in-class solutions that provide higher value to customers, and promote the use of field wireless technologies.

ISA100 is a wireless technology that is based on the ISA100.11a standard. It includes ISA100.11a-2011-communications, an application layer with process control industry standard objects, device descriptions and capabilities, a gateway interface, infrared provisioning and a backbone router.
