Frequently Asked Questions (FAQ)

Q: Does this transmitter include a gas sensor?

A: No. The XNX-UTAI-NNNNN comes without a sensor. You connect external IR detectors like Searchline Excel.

Q: What is the difference between this model and XNX-UTAV-NNIV1?

A: The UTAI is an IR interface transmitter (no built-in sensor). The UTAV includes a methane IR sensor. Choose based on your detector type.

Q: Can I use this with a catalytic bead sensor?

A: No. This model is designed only for IR products. For catalytic bead, choose the mV personality version.

Q: How long is the warranty and shipping time?

A: 12-month warranty against defects. We ship within 12-24 hours via FedEx, UPS, or DHL.

Q: Is this approved for use in North America?

A: Yes. It holds UL, CSA, and FM approvals for hazardous locations.

Selection Guide – Which One to Choose?

• Already have an IR detector? – Choose XNX-UTAI-NNNNN as a transmitter.
• Need a standalone methane detector? – Select XNX-UTAV-NNIV1 with built-in IR sensor.
• Check your wiring needs – 5 entries give more flexibility than 4-entry models.
• Consider communication – HART is standard; optional relays or MODBUS available.

Compare with Other Models
