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.

Since the 1970s, Yokogawa has partnered with power producers to squeeze every watt of efficiency and resilience from assets old and new. Today our 30,000+ CENTUM control systems and 230 service hubs span 100 countries, uniting domain know‑how, ISASecure™‑certified automation, and real‑time analytics. Whether you run a single gas turbine or a continent‑wide renewable fleet, we deliver the insight, safety, and speed you need to thrive in a decarbonizing grid.

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. 

Condition severe service analysis needs with a simple self-contained two stage system

Optimize plant performance with proven analytical services

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.
