Blind Transmitters: A return to the basics
Analog transmitters easily send process measurements from different areas in a plant to a central PLC where process control decisions can be made based on transmitter feedback. Analog transmitters are great cost-saving alternatives to single-point controllers. In situations where multiple sensing locations are required, single point controllers costs can add up quickly.
Build reliability in during design
Instrumentation that promises to improve reliability may not always be what they seem. You have to consider whether a site can properly maintain sophisticated instruments.
Build your portfolio
Is energy efficiency an engineering project or a management process? Contributing Editor Christopher Russell answers that question in this month's Energy Saver column.

China teems with harmful exports
Problems with Chinese manufacturing go well beyond defective and dangerous products, Mark Rosenzweig, editor in chief, notes in this month's installment of From the Editor.
Consider the impact of slope, fittings and valves. Plants can lose sizable amounts of money each year because of contamination caused in process lines. Owners and contractors alike can take steps in the design and construction phase to enhance the drainability and cleanability of a system.
Integration of plant-floor, building, physical security, and enterprise network means more changes for unathorized access and more need for intelligent security, cooperation, and training.
