Selection Comparison and Engineering Advice

Choose your industrial transmitter hardware based on local hazard certifications and field network protocols.

• Model Comparison: Honeywell XNX-AMAV-NHIF1 uses ATEX/IEC approvals with M25 entry threads and local HART, while the XNX-UTSE-FNIF1 uses UL/CSA approvals with 3/4 inch NPT threads and Foundation Fieldbus.
• Technical Recommendation: Select the XNX-UTSE-FNIF1 for North American plants that require Foundation Fieldbus digital control networks. Choose the Honeywell XNX-AMAV-NHIF1 for European installations using standard analog loops and local HART calibration tools.

Field Installation and Wiring Instructions

• Secure the heavy metal casing onto a solid structural wall or mounting pipe support.
• Pull field power wiring through the dual 3/4 inch NPT conduit access holes cleanly.
• Wire the digital communication loop cables directly into the internal Foundation Fieldbus terminal strip.
• Connect dedicated grounding cables to internal and external earthing points before powering up.
• Screw the infrared Propane sensor cell securely into the bottom sensor port housing.
