Foxboro
The Foxboro Company was founded in 1914. At the moment the Foxboro Company is a part of Invensys plc. Group of companies and is one of the biggest companies working in the fields of automation. Invensys plc. Group of companies is a global electronic and engineering company.
Equipment offered by the Foxboro Company is sorted out into the following groups:
- Distributed control systems and emergency automation hardware and software;
- Instrumentation.
Distributed control systems and emergency automation hardware and software.
The Invensys plc Company control systems and emergency automation equipment are one of the most competitive in the world. Object under control can be of any complexity – from ten to tens of thousands parameters. "I/A Series" control system hardware and software, produced by Foxboro Company, are used as a kernel to build distributed control system. "I/A Series" system is up-to-date "open" industrial system, functioning under control of Windows NT and Unix operational systems.
Systems integrated supply is Company's often practice. The supply includes as well equipment of the other companies which are part of Invensys plc. Company. At the same time warranty is given to the whole delivery set. In accordance with customer wish it is possible to include third companies' different auxiliary equipment in the set of the control system under supply.
Instrumentation.
Flow rate measuring devices.
- Diaphragms with differential pressure transducers;
- Mass flow meters;
- Induction flow meters, fettled with Teflon or ceramics;
- Multivariate sensors with flow rate recalculation;
- Vortical and turbine flow meters;
- Flow rates correction and recalculation units, including heat consumption control.
Pressure measuring devices.
- Electronic and pneumatic pressure transducers;
- External separating diaphragms.
Level measuring devices.
- Buoy level transducers with electric and pneumatic output;
- Hydrostatic level transducers also measuring density;
- Levels control system for tank fields on the basis of hydrostatic level meters.
Temperature measuring devices.
- Thermocouples and temperature transducers for them;
- Resistance thermometer and temperature transducers for them;
- Universal temperature transducers.
Electric conductivity, pH, water oxygen content measuring devices.
- pH, reduction/oxidation potential, dissolved in water oxygen content transducers;
- conductometric transducers;
- electrodes and sensors;
- electrodes clean-up system.
Mediums composition measuring system on the basis of nuclear- magnetic resonance (NMR).
- system is intended to analyze oil products quality in different oil refining processes.
All main transducers (pressure, flow rate, level, temperature, electrochemical) are "intellectual", which allows to make digital integration with "I/A Series" control system upper level using such communications protocols as FoxCom, Fieldbus H1, Profibus and others.
