The Regional Transport of Ozone
EPA tracks emissions of six principal air pollutants - carbon monoxide, lead, nitrogen oxides, particulate matter, sulfur dioxide, and volatile organic compounds. All have decreased significantly since passage of the Clean Air Act in 1970 - except for nitrogen oxides.
Process Control Network Security - Reference Architecture
This document describes best practices for the reference architecture for a process control system network and its interfaces to a corporate network. The papers objective is to give the reader an understanding of the techniques utilized to securely connect these networks.
Design Tips for Sensing Probes
This application note from Delta Controls outlines selection and installation criteria for using admittance probes to monitor the level of powders, liquids and other materials. Dielectric constants of more than 200 materials are included.
Accurate liquid phase density on aerated liquids
This white paper discusses SONAR-based, clamp-on gas volume fraction meters which recently have been introduced to the industry that provide an accurate, real time, measurement of entrained gases. Coupling entrained gas volume fraction monitor with most types of process density meters, enables accurate determination of liquid and the liquid-solid components of aerated mixtures.
Specifying industrial fieldbus networks for automation
Automation designers face many challenges and tradeoffs in the development of a successful network solution. This white paper discusses the necessary choices in selecting a network technology appropriate for various specific applications.
Measurement Best Practices
This 9-page PDF discusses way in which you can ensure your measurements are accurate, repeatable and reliable.
Energy Efficiency - The Other Alternative Fuel
Proven methods for industry to reduce energy consumption and environmental impact are already at hand. These cost-effective solutions promise substantial return-on-investment now and in the future, without sacrificing performance or quality. For most companies and organizations, the answers to maintaining a competitive edge in this era of rising energy costs are readily available. By applying a suite of cost-effective power and automation solutions from technology leaders like ABB, these facilities can achieve substantial energy savings today without waiting for the "alternative fuels" of the future.
Securing Process Control Network External Communications
In the real world, sharing PCN data with external systems and accessing PCN systems from external
sources is fast becoming a business necessity. This paper provides some generic guidelines for enabling
secure connectivity between PCNs and external systems.
PACs for industrial control: The future of control
With a number of vendors producing Programmable Automation Controllers that combine the functionality of a PC and reliability of a PLC, PACs today are increasingly being incorporated into control systems. This white paper explores the origins of the PAC, how PACs differ from PLCs and PCs, and the future direction of industrial control with PACs.
Hazard Communication Guidelines for Compliance
OSHAs Hazard Communication Standard (HCS) is based on a simple conceptthat employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working.
Electro-hydraulic system design: Making the right system choices
Designers who understand and can take advantage of the differences between fluid power and traditional electromechanical power can build machines that produce higher quality output with lower lifecycle costs. This white paper suggests that care must be taken, however, in selecting and sizing the hydraulic system elements and in tuning the motion controller for optimal performance.
Technology expands flowmeter capabilities, reduces costs
Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.
