Honeywell's XNX-UTAV-NNCB1 is an advanced gas detection transmitter specifically designed for monitoring combustible gases. This unit has a catalytic bead sensor capable of assessing levels within the range of 0 to 100% Lower Explosive Limit (LEL). It is engineered to handle challenging conditions, weighing a manageable 5 lbs, and encased in a durable housing crafted from painted LM25 aluminum with a marine-grade finish, ensuring longevity.

A voltage input between 16 and 32 Vdc powers the device, and the power consumption is rated at 6.5 watts. The XNX-UTAV-NNCB1 functions effectively across a temperature spectrum of -40°C to 65°C, making it suitable for various environmental challenges; however, performance may vary based on specific sensor configurations. The humidity operational range lies between 20% and 90% relative humidity, without the danger of condensation.

Rated for protection, this transmitter has a NEMA 4X/IP66 IP rating, ensuring resistance to water and dust ingress. It communicates via HART over a 4-20 mA signal without a relay module. The transmitter includes four 3/4” NPT cable entries, out of available options for connectivity. A 2.5-inch backlit LCD display offers high-resolution dot matrix visuals, simplifying data reading in different lighting conditions.

In terms of compliance, the unit has received approvals from UL/CSA and is classified for use in Class I Division 1 areas and Groups B, C, and D. The XNX-UTAV-NNCB1 combines advanced gas detection capabilities with a robust design, making it ideal for safety-critical applications.
