The TURCK FCS-G1/2A4-NA-H1141 is a robust flow sensor tailored for liquid flow detection in hazardous zones. It features a G1/2" process connection and provides a NAMUR output, making it ideal for intrinsically safe circuits in ATEX-certified environments. The sensor detects flow presence or absence and integrates easily with isolation amplifiers. Its rugged design, reliable performance, and IP67 protection ensure long service life in chemical plants, oil & gas, and other critical process control applications. Key Features: • Flow sensor for liquid media in hazardous areas • G1/2" process connection (BSPP thread) • Output type: NAMUR (for intrinsically safe applications) • Designed for use with isolation amplifiers • Operating voltage (via isolator): typically 8 VDC • IP67 environmental protection • ATEX-compatible design for Ex zones • Suitable for chemical processing and oil & gas industries
