Foxboro

Foxboro is a leading American manufacturer of precision process instrumentation and measurement and control technology for the petrochemical industry, energy sector and process chemistry. As a division of Schneider Electric, Foxboro supplies pressure transmitters, differential pressure transmitters, flow meters, level transmitters, process analyzers, process controllers and integrated process control systems for critical industrial applications. With a catalog of 1,125 products, Foxboro offers a complete portfolio for process monitoring and control.

Foxboro IGP-series pressure transmitters are among the most trusted instruments in the petrochemical industry. They measure absolute and gauge pressure with accuracies to ±0.04% of measurement range and are available for pressure ranges from 0-10 mbar to 0-700 bar. Special versions for corrosive media are available with PTFE diaphragms and Hastelloy C housings. Smart HART and Foundation Fieldbus communication options enable integration into advanced process control architectures.

Foxboro differential pressure transmitters are used for flow measurement via Venturis, orifice plates and Pitot tubes, as well as for level measurement in sealed tanks. The IDP10 and IDP20 transmitter series have ultra-low static pressure errors and withstand line pressures up to 420 bar. Multi-variable transmitters simultaneously measure differential pressure and line pressure for combined mass flow calculation.

Foxboro analyzers include pH meters, conductivity meters, oxygen analyzers, chlorine analyzers and process gas chromatographs for real-time monitoring of process liquid and gas composition. Foxboro process controllers and distributed control systems (DCS) of the I/A Series offer advanced control algorithms for complex multi-variable process optimization in refineries, petrochemical plants and power stations.

At Verkopershulp.nl you will find the complete Foxboro range with direct availability of common models. Our technical experts help you select and configure Foxboro instruments for your specific process application.

History

Foxboro was founded in 1908 in Foxborough, Massachusetts, USA, by Charles Belden as a manufacturer of precision measuring instruments. The company was a pioneer in developing pneumatic process control technology and introduced the first industrial process control installations in the 1920s. In the 1960s and 1970s, Foxboro took a leading position with the introduction of the first digital process instruments. In the 1990s, Foxboro launched the I/A Series distributed control system that revolutionized integrated process management. Foxboro was later acquired by Invensys and subsequently by Schneider Electric, which positions Foxboro as its leading process automation division.

Frequently Asked Questions

What is the accuracy of Foxboro pressure transmitters?
Foxboro IGP-series pressure transmitters offer reference accuracy of ±0.04% to ±0.1% of measurement range depending on the model. The total measurement error including temperature and static pressure effects is typically less than ±0.25% over one year under calibrated conditions. This makes them suitable for fiscal and quality-critical measurement.
Which communication protocols do Foxboro transmitters support?
Foxboro transmitters support HART (4-20 mA with digital HART communication), Foundation Fieldbus H1, Profibus PA and wireless WirelessHART communication. HART communication allows instrument parameters to be read, configured and diagnosed via a HART communicator or Asset Management Software without interrupting the analog signal.
Are Foxboro transmitters suitable for use in explosive environments?
Yes, Foxboro supplies transmitters certified for use in explosive environments conforming to ATEX Directive 2014/34/EU for zone 1 and 2 (gaseous explosives) and zone 21 and 22 (dust explosive environments). IECEx certification is available for international installations. FM and CSA certifications are available for North America.
How do I calibrate a Foxboro pressure transmitter?
Foxboro pressure transmitters are calibrated by verifying the zero and span against a certified reference pressure source. Calibration is possible via HART communicator, the local display or a wired calibration step on the instrument. Foxboro recommends calibration intervals of 12 to 24 months depending on the application and required measurement accuracy.
What is the difference between Foxboro IGP and IDP transmitters?
Foxboro IGP transmitters measure absolute pressure or gauge pressure relative to atmospheric pressure. IDP transmitters measure differential pressure, the pressure difference between two connection points. IDP transmitters are primarily used for flow measurement via primary elements (orifice plates, Venturis) and for level measurement via the hydrostatic method.
Are Foxboro analyzers suitable for online process monitoring?
Yes, Foxboro pH, conductivity and oxygen analyzers are specifically designed for continuous online process monitoring in liquid streams, tanks and reactors. They provide stable measurements over extended periods with minimal maintenance thanks to digital sensor compensation and integrated cleaning cycles for electrode cleaning in contaminated media.
Does Verkopershulp.nl offer technical support for Foxboro instruments?
Yes, Verkopershulp.nl has technical specialists who support you in selecting and configuring Foxboro process instrumentation. We advise on choosing the correct transmitter type, measurement range, material specification and communication protocol for your process installation.
