Configured for Coriolis measurement processing in industrial flow networks, the YOKOGAWA RCCF31 (RCCF31) Mass Flow Converter provides direct physical and electrical execution for ROTAMASS 3 Series meter platforms.

Hardware Specifications

Channel Isolation and Process Fieldbus Architecture

The converter incorporates channel-to-channel optical and galvanic isolation circuitry designed to eliminate ground loops and electromagnetic interference across multi-variable process measurement loops. Signal conditioning stages execute advanced digital signal processing on raw sensor inputs to extract precise mass flow, density, and temperature values. Integrated communication modules support 4-20 mA HART loop protocols and FOUNDATION Fieldbus connectivity, ensuring deterministic data exchange and robust diagnostic reporting to central control systems.

Frequently Asked Questions

Q: What power supply options are compatible with the RCCF31 converter unit?

A: The device accepts dual power supply inputs ranging from 90 to 250 VAC or a direct 24 VDC source.

Q: Does the unit support hazardous environment installations?

A: Yes, the flameproof housing holds extensive explosion protection certifications including ATEX, FM, IECEx, NEPSI, KOSHA, and INMETRO.

Field Installation Guidelines

Mount the RCCF31 flameproof housing securely onto vertical or horizontal pipes using appropriate mounting brackets, ensuring adequate clearance for display viewing and terminal access. Terminate sensor drive and pickup cables into the internal compartmentalized terminal blocks using shielded twisted-pair wiring, ensuring shield drain wires are grounded to the designated earth terminal. Verify power supply voltage levels and confirm enclosure cover threads are fully engaged prior to hazardous area energization.
