Technical Principles and Innovative Values
The Foxboro 8002A-SCR-PJGFGZ-V stands out in flow measurement due to a combination of proven principles and innovative design choices:
Electromagnetic Induction Principle:At its core,the 8002A-SCR-PJGFGZ-V operates on Faraday’s Law of Electromagnetic Induction.Two coils generate a uniform magnetic field perpendicular to the flow direction.As a conductive liquid passes through this field,an electromotive force(voltage)is induced across the liquid,perpendicular to both the flow and the magnetic field.This induced voltage is directly proportional to the fluid’s velocity,allowing for highly accurate volumetric flow measurement.This principle means the measurement is independent of fluid density,viscosity,temperature,or pressure,offering high accuracy for diverse conductive liquids.
Sanitary and Robust Construction:The 8002A-SCR-PJGFGZ-V features a polished ceramic lining and platinum electrodes.The ceramic lining is extremely hard,abrasion-resistant,and chemically inert,making it ideal for aggressive fluids and high-temperature applications.Its polished surface is crevice-free,preventing product buildup and bacterial growth,crucial for sanitary applications.Platinum electrodes offer excellent corrosion resistance and signal stability.Coupled with Tri-Clamp sanitary connections,this design ensures compliance with strict hygienic standards(like FDA regulations for food contact service),simplifying cleaning-in-place(CIP)processes and minimizing contamination risks.
Pulsed DC Coil Excitation:The 8002A-SCR-PJGFGZ-V is calibrated for use with pulsed DC coil excitation from a compatible transmitter(like the IMT25).This technique helps to virtually eliminate common electrical noise and zero drift issues,enhancing measurement stability and accuracy,especially at low flow rates.This advanced coil drive contributes to the flowtube’s long-term stability and reliable signal integrity.
NEMA 4X/IP66 Environmental Protection:The robust housing of the 8002A-SCR-PJGFGZ-V meets NEMA Type 4X and IEC IP66 standards.This means it is designed to withstand harsh outdoor or in-plant environments,providing superior protection against dust,water jets,and corrosive agents.This level of environmental resilience extends the flowtube’s operational life and ensures reliable performance even in challenging industrial settings.
Application Cases and Industry Value
In a large-scale craft brewery,the consistency of wort and beer transfer between fermentation tanks and bottling lines is paramount for product quality and yield.They historically used mechanical flow meters that were prone to clogging,required frequent cleaning,and often resulted in inconsistent batch sizes.After experiencing recurring issues that led to significant product waste and increased cleaning cycles,the brewery decided to upgrade to Foxboro 8002A-SCR-PJGFGZ-V magnetic flowtubes paired with IMT25 transmitters.
The installation of the 8002A-SCR-PJGFGZ-V at critical transfer points immediately yielded tangible benefits.Its non-obstructive design eliminated clogs and pressure drops,maintaining product integrity.The ceramic lining and Tri-Clamp connections drastically simplified CIP procedures,reducing cleaning time by 20%and chemical consumption.Operators reported”unprecedented accuracy”in batching,reducing overfill and underfill,which led to a 5%increase in usable product yield per batch.Furthermore,the robust,sanitary design of the Foxboro 8002A-SCR-PJGFGZ-V significantly reduced maintenance frequency and improved overall equipment uptime,proving its immense contribution to operational efficiency,product quality assurance,and compliance with food safety standards in a demanding brewing environment.
Related Product Combination Solutions
The Foxboro 8002A-SCR-PJGFGZ-V flowtube is one half of a complete flow measurement solution.It requires a compatible transmitter and can be part of a larger Foxboro control system:
Foxboro IMT25 Intelligent Magnetic Flow Transmitter:This is the dedicated transmitter designed to work with the Foxboro 8002A-SCR-PJGFGZ-V.It provides the pulsed DC coil excitation and converts the raw voltage signal from the flowtube into a standard 4-20mA output,as well as digital communication(e.g.,HART,FoxCom,or FOUNDATION Fieldbus).
Foxboro 8000A Series Magnetic Flowtubes(other sizes/configurations):Other models like 8001A-SCR(1-inch sanitary ceramic)or 8003A-SCR(3-inch sanitary ceramic)would be used for different line sizes within the same sanitary applications,maintaining consistent measurement technology.
Foxboro I/A Series DCS(e.g.,CP series processors,FBM I/O modules):For integrated process control,the output from the IMT25 transmitter connected to the 8002A-SCR-PJGFGZ-V would feed into I/A Series controller processors(like CP60 or CP40)via analog input FBMs(e.g.,FBM204).
Foxboro Coriolis Mass Flowmeters(e.g.,CFS10,CFS20):While the 8002A-SCR-PJGFGZ-V measures volumetric flow,Coriolis meters provide direct mass flow measurement,often used in conjunction for mass balance critical applications.
Sanitary Process Valves and Fittings:Since the 8002A-SCR-PJGFGZ-V features Tri-Clamp connections,it seamlessly integrates with standard sanitary valves,pumps,and other stainless steel fittings common in hygienic industries.
Calibration Rigs and Standards:To ensure the long-term accuracy of the 8002A-SCR-PJGFGZ-V and its paired transmitter,regular calibration using certified flow calibration rigs is essential.
Installation,Maintenance,and Full-Cycle Support
The installation of the Foxboro 8002A-SCR-PJGFGZ-V is straightforward due to its wafer-body design and standard Tri-Clamp connections.Before any installation,always ensure proper lockout/tagout procedures are followed for safety,and the piping system is fully depressurized and drained.The 8002A-SCR-PJGFGZ-V mounts between two mating flanges or directly into Tri-Clamp unions.Careful alignment is crucial to prevent mechanical stress on the flowtube and ensure accurate measurement.Electrical connections to the paired IMT25 transmitter require a dedicated,shielded cable,and meticulous wiring according to the Foxboro installation manual is paramount to minimize electrical noise interference and ensure proper signal transmission.Given its IP66/NEMA 4X rating,the 8002A-SCR-PJGFGZ-V is highly resilient to harsh environments,but ensuring proper grounding and conduit sealing maintains its integrity against moisture and dust over time.
Routine maintenance for the Foxboro 8002A-SCR-PJGFGZ-V is minimal,largely due to its non-obstructive design and robust ceramic lining that resists fouling and abrasion.The primary maintenance activities revolve around periodic visual inspection for any external damage or leaks at the connections,and ensuring the associated IMT25 transmitter is performing optimally.For sanitary applications,routine cleaning-in-place(CIP)cycles are integral,and the Tri-Clamp connections facilitate easy removal for manual inspection if needed.Calibration verification is recommended periodically to ensure sustained accuracy,using either a primary flow calibration rig or a certified secondary standard.In the event of an issue,troubleshooting typically focuses on the transmitter or wiring,as the flowtube itself is highly reliable.Our team at Shenzhen Changxin provides comprehensive support for the Foxboro 8002A-SCR-PJGFGZ-V,offering expert guidance on installation best practices,preventative maintenance schedules,and efficient fault resolution.We maintain a reliable stock of genuine and high-quality refurbished units,ensuring quick access to critical spares to minimize your operational downtime.Our commitment extends to providing full-cycle support,ensuring the longevity and peak performance of your Foxboro flow measurement solutions.
