Yokogawa AXFA14G-E1-41/SB/SCT Magnetic Flowmeter Remote Converter

The Yokogawa AXFA14G-E1-41/SB/SCT, also cataloged as the AXFA14G Magnetic Flowmeter Remote Converter, operates as a dedicated hardware component for magnetic field excitation and fluid velocity signal processing within DCS and process automation loops.

Hardware Specifications

Process Control Signal Integration and Isolation Architecture

• Executes simultaneous analog flow signal transmission and digital parameter configuration using the superimposed 4-20 mA HART loop protocol.
• Features internal channel-to-channel isolation hardware to isolate primary sensing coils, signal processing logic, and output loops from external earth loop interference.
• Incorporates cold junction and ambient thermal compensation processing within internal calculation loops to ensure stable signal digitization across varying enclosure environments.

Frequently Asked Questions

Q: What power options are supported by the AXFA14G-E1-41 unit?

A: The converter accepts universal primary power ranging from 100 to 240 V AC (50/60 Hz) or 100 to 120 V DC across its main supply terminals.

Q: How is physical line noise minimized on the remote sensor cable connection?

A: The hardware employs dedicated high-impedance input amplifier circuitry with channel-to-channel galvanic separation to isolate raw flow noise from the output stage.

Q: What cable entry thread specification is configured on this model?

A: The electrical connections feature ISO M20 x 1.5 female threaded conduits for field wiring gland integration.

Field Installation Guidelines

• Secure the remote converter to a vertical pipe or mounting plate using the provided /SB JIS SUS304 stainless steel bracket, ensuring all mounting bolts are torqued evenly.
• Route signal wiring through the ISO M20 x 1.5 cable entries using certified IP-rated cable glands to preserve the weather-tight seal of the housing.
• Ground the converter enclosure frame using a low-impedance copper earth strap attached directly to the local plant ground grid.
• Verify power supply line voltage matches the 100-240 V AC or 100-120 V DC specification before applying power to the main supply terminals.
