SIL2 / SIL3 rated vibronic point level measurement devices for overfill protection
Liquids are handled in all process facilities. This includes tank farms, food plants, chemical or pharmaceutical production sites and water and wastewater industry facilities. Some of these liquids are toxic, flammable, reactive or create explosive gases which cause risks for the environment or personnel. An operator of a facility or a plant has to assure that these dangerous liquids are kept in the appropriate pipes, tanks and vessels. In particular, overspilling of a tank has to be avoided during filling processes.

Addressing "Impossible to Measure" pH Applications in the Inorganic Pigments Industry

This white paper explains how automated, retractable pH systems provide a solution in the process measurement of pH in difficult pigment applications.  Flexible system design allows the operator to tailor the operation to increase sensor life, reduce maintenance requirement, and improve measurement accuracy. Net benefits to the plant are realized in reduced maintenance and operating costs as well as increased product quality and tighter process control.

Process automation system independent processing monitor and field device management
Chemical manufacturers and distributors alike are seeking better ways to more efficiently manage the assets of their operations. This paper describes the application of the Fieldgate HART to XML based field server and the open standard Fieldcare Field Device Tool (FDT) to gain on demand access to selected HART devices over wired and wireless Information Technology based Local Area Networks (LAN) and Wide Area Networks (WAN). Visibility of and access to field device information contributes to efforts to improve the life cycle management of process plants and associated distribution operations.

Establishing a balanced maintenance strategy for field instrumentation

Field Instrumentation devices are crucial to reliable process plant operation but often they are not included in the maintenance plan since their reliability is relatively high, but effects of age and technological obsolescence lead to reduced plant performance over time. New legislation demands more control and re-calibration, manufacturers promise very stable and highly reliable instruments. The challenge is now to newly balance the maintenance efforts and their payback.
