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.
Design Tips for Selecting 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.
Taking Toxics Out of the Air
This 34-page PDF white paper discusses the technology and performance-based standards implemented by the EPA during the last 10 years and how they will assist in removing harmful toxins from the air.

Hygienic Feeder Design
Specifying a hygienic bulk solids feeder is not a simple task. The wide variety of requirements needed
for specific applications are similar in scope to explosion proof environmental requirement variations.
Security vulnerability assessment revealed
Plant security is a key priority at many plants. This 10-page paper provides background what the methodology for a plant vulnerability analysis involves. It covers topics such as how to get started, available tools, and risk assessment.
