Fisher-Rosemount is making its industrial process control products compatible with the Foundation fieldbus protocol, one of several proposed standards covering this area. By following the standards its PlantWeb Builder suit of products will give added versatility to the company’s existing line-up of 800 fieldbus products.
Builder is dedicated to inter-operable global systems, using the slogan ‘control anywhere, information everywhere’. It can also interface with third-party products through communications standards including 4 20mA, Hart, discrete I/O, OPC and Modbus.
Builder products will include DeltaV, a scaleable network development package, DVC5000f series digital valve controllers, Rosemount model 3051 pressure transmitters and model 3244MV temperature transmitters, as well as the asset management package AMSinside.
Chem Resist has installed four Turbulent Contact Absorption fume scrubbing systems at LG Electronics’ £425m monitor making plant in South Wales.
The systems meet the demand for high flow rates, lower capital costs and flexibility, and have a combined flow rate of 93,000m3/hr.
The installation included a further scrubbing unit with a flow rate of 35,000m3/hr and four 20,000 litre sodium hydroxide storage vessels.
The TCA system is said to improve on conventional packed-bed columns by offering lower capital investment per cubic metre of gas flow, the ability to treat gases containing particulates, and system flexibility. Capacity could be increased without structural changes to the absorption towers if environmental laws are tightened further.
Eurotherm specialist Viatran has developed tank-level sensors to overcome the problem of condensation getting into the electronics of hydrostatic transmitters.
The model 395 pressure transmitter has a choice of adaptors for flush hygienic mounting, providing fast recovery of measurement accuracy compared with other transmitters, especially where the process involves high temperature fluids.
