Modern "smart" instruments offer immense flexibility, but with that flexibility comes the risk of misconfiguration.
The process industry relies entirely on the accuracy of its field devices. Without precise data from measurement sensors, control systems cannot make informed decisions. Without reliable final control elements, those decisions cannot be executed. This comprehensive technical guide explores the engineering principles, design criteria, installation standards, and maintenance strategies required to master these critical components. Some of the latest trends and technologies include:
The field of modern measurements and final elements is constantly evolving, with new technologies and trends emerging regularly. Some of the latest trends and technologies include: intrinsic safety barriers
Rotary movement. A V-notched segment rotates against a seal. Offers high capacity, excellent turndown, and can slice through shear-sensitive fluids or slurries. Without reliable final control elements
Installation in hazardous areas demands specialized techniques. Explosion-proof enclosures, intrinsic safety barriers, and purged/pressurized systems each provide different protection concepts. Intrinsically-safe installations — which limit electrical energy to levels insufficient for ignition — offer the advantage of allowing live maintenance using conventional test equipment in hazardous areas.
