The CENTUM CS 3000 / UOI was selected for this project. The control platform in the UOI is the GE Fanuc CIMPLICITY Human Machine Interface (HMI) system, which fully integrates the controls for the turbine and BOP auxiliaries and uses the same screens/formats at both the turbine and BOP HMI displays. The CIMPLICITY HMI used in the UOI is a SCADA based design that fully supports the customer's requirement for remote operation capability.

DP Level transmitter configuration can be very time consuming. Yokogawa DPharp EJA/EJX Pressure transmitters realize reduction in man hours by smart level setup feature.

Measures temperature and vibration of the turbine for rapid identification of abnormalities.

What if you could detect signs of abnormalities in bus ducts (bus bars) quickly during maintenance and inspection work and respond to them at just the right time? Yokogawa DTSX monitoring solution constantly monitors connections that tend to deteriorate over time and contributes by pinpointing abnormality locations and reducing workload of maintenance personnel, helping to ensure stability in plant operations.

Yokogawa ensures a reliable heat and CO₂ transfer system by using the standard GPRS protocol. The exclusive use of webbased technology enables the market gardeners to go online to order heat and CO₂ and view information.

One of the most common applications for differential pressure transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.

STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.

Floating-point format calculations have enabled physical quantities (in engineering units) to be used in calculations.

Industrial hydrogen fuel cells can be used to produce hydrogen and oxygen from distilled water as well as run in reverse to generate electricity. Fuel cells can also be used in conjunction with intermittent energy sources like solar or wind to provide regulated continuous energy output.

Seawater leak detection is the post-condensation water quality management processes. Damage to the ion exchange resin, which deionizes the supplied water, is also monitored during this process, and both of these applications are executed by a conductivity analyzer. (AN10D01P01-01E)

Industrial Combustion sources such as thermal cracking furnaces and, process heaters play a critical role in the process industry.

This paper introduces the ADMAG AXR 2-wire magnetic flomwmeter solution for chilled water application in air conditioning unit.

Industrial facilities where power and steam is produced (i.e., Cogeneration) exhibit a very good potential for real time monitoring and optimization using Visual MESA Energy Management System.

Based on our extensive experience, overall benefit in the range of 2% to 5% of the total energy cost can be achieved. Expected project payback is always less than one year.

Visual MESA was successfully applied to many industrial facilities worldwide, several of them operating steam and power generation networks of different complexity and capacity but all with energy cost savings. 

Chemical plants, nuclear power plants, and large-scale engineering systems including railways and aircraft must be operated at least safely enough so as to not affect the surrounding environment. Furthermore, it is apparent that even only one accident or problem becomes the target of fierce criticism from the general public, as seen in the response of people to the accident of the Fukushima I Nuclear Power Plant of the Tokyo Electric Power Company and the problems with Boeing's 787 jetliners.

Recently, there is an increasing demand for operation and monitoring of all the various controllers distributed in the field on the same screens to improve plant operation efficiency. The purpose of the Unified Gateway Station (UGS) is to connect external controllers, such as the STARDOM's FCN/FCJ autonomous controllers and other vendors' controllers, to the CENTUM VP integrated production control system and to operate and monitor those external controllers on the Human Interface Station (HIS) screens, the operation and monitoring screens for the CENTUM VP.

We have developed the "Econo-Pilot" energy-saving system for water pumps, which reduces the power consumption of motors for water supply. In the energy-saving control field, the conventional method used is that of constant pressure control of the water supply with inverters.

The engineering phase holds the largest ratios in control system configuration in terms of both time and money, so improving engineering efficiency is one of the biggest issues when it comes to system integration. In the STARDOM, Application Portfolios (APPF) are devised to dramatically slash engineering costs and increase software reliability.

Yokogawa Electric Corporation, one of the leading manufacturers of industrial recorders, put the DAQSTATION DX series stations on the market in 1999, which added information processing and transmission functions to conventional recorders.

Yokogawa has been offering the EXA200 series two- wire liquid analyzer for processes since 1990. This analyzer has been used in various fields including the quality control of raw materials in process plants in the electric power and petrochemical industries, reaction management of products, quality control in waste water facilities, and quality monitoring of river water and tap water.

DTSX has been increasingly used in variety of applications such as fire detection, leak detection and preventative maintenance.
