Installation Guidelines

• Mount the heavy metal housing securely onto a rigid flat surface or structural steel pipe frame using approved hardware.
• Route field wiring through the pre-cut 3/4" NPT conduit entries using certified explosion-proof cable glands or sealed metal conduits.
• Connect standard three-wire 4-20mA signal lines and point-to-point HART network cables according to official engineering terminal diagrams carefully.
• Seal all unused enclosure entry ports with heavy threaded plug accessories to preserve strict IP66 liquid protection standards.
• Ground the outer stainless steel housing structure locally to shield internal electrical circuits from heavy electromagnetic radiation interference.

Packaging and Shipping Details

• Factory box contains one pre-configured base transmitter body alongside the designated infrared carbon dioxide sensor cartridge unit.
• Logistics team packs every heavy instrument inside high-density protective foam boxes to absorb harsh shipping impacts completely.
• We ship all international industrial orders rapidly through premium global carrier channels like FedEx, UPS, and DHL Express.

Frequently Asked Questions

• Does this specific transmitter configuration include internal alarm output relays?
  • No, the letter N in the model code indicates that factory workers installed no optional relay board inside.
• Can technicians perform field calibrations without opening the heavy metal cover?
  • Yes, field crews use the magnetic wand tool or local HART communicator to adjust settings safely in hazardous spaces.
• What physical housing material protects the internal electrical sensor components?
  • Honeywell manufactures this enclosure with high-grade 316 stainless steel to withstand severe chemical and offshore environments.
