ISA Analysis Division Symposium 2019

Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.

In the mid 1970s, Yokogawa entered the power business with the release of the EBS Electric Control System. Since then, Yokogawa has steadfastly continued with the development of our technologies and capabilities for providing the best services and solutions to our customers worldwide.

Yokogawa has operated the global power solutions network to play a more active role in the dynamic global power market. This has allowed closer teamwork within Yokogawa, bringing together our global resources and industry know-how. Yokogawa's power industry experts work together to bring each customer the solution that best suits their sophisticated requirements.

The PH450 pH and ORP analyzer is a multivariable analyzer that combines pH with temperature and ORP (Redox) measurement, which can be utilized through different output functions: two mA current outputs, four independent SPDT contact outputs and HART. 

The Yokogawa Advanced Reflux Sampler is designed to provide conditioning for severe service analysis needs using a simple self contained two stage system. The first stage is designed to provide filtration of particulate and passive cooling.

The PH400G EXA PH intelligent pH analyzer is a highly reliable advanced function pH measurement system designed for wide application in all industries such as for medium-scale waste water treatment system, and general-purpose pH measurement and control systems.

The PH400G features highly effective built-in functions for electrode diagnosis that are similar to those of the EXA PH202 2-wire pH/ORP analyzers. These functions monitor sensor errors even while pH measurements are in progress, enabling more highly reliable pH measurement.

The PH400G also offers an interactive system for setting various parameters, facilitating effective use of its wealth of functions.
