Thanks to this agreement, Cosasco will have the ability to offer its corrosion monitors in combination with Yokogawa field wireless devices and is expected to increase sales. For Yokogawa, the addition of corrosion sensors to its lineup of field wireless devices will help its customers efficiently maintain facilities and ensure safety at their plants.

Overview of the Tie-up and its Objectives
With a field wireless system, plant field devices and analyzers 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.

Cosasco has a long global track record in supplying various kinds of corrosion monitors to the oil and gas, petrochemical, chemical, and other industries, and Yokogawa has developed ISA100 Wireless-based technologies and products such as wireless access points and management stations.

Through this agreement, Cosasco 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. On the other hand, Yokogawa aims to increase sales for its field wireless business by being able to offer a wider field wireless device lineup.
