Frequently Asked Questions

• What gases can this transmitter detect?
  • It detects any toxic gas or oxygen using the corresponding MPD sensor cartridge (ordered separately).
• Is the sensor included?
  • No. The XNX-UTAE-NNNNN comes without a sensor. You must purchase the correct electrochemical cartridge for your target gas.
• Can I use this in a Class I Division 1 area?
  • Yes, it is UL/CSA approved for hazardous locations (verify specific certificate).
• How do I calibrate the transmitter?
  • Use the magnetic wand to enter calibration mode without opening the housing. Follow the menu prompts.
• What is the maximum cable length for 4-20 mA?
  • Up to 1000 meters (depending on cable gauge and power supply).
• Does it support Modbus?
  • No. It supports 4-20 mA with HART only. Modbus requires additional gateway.

Buyer’s Guide & Selection Advice

• Choose the correct sensor cartridge for your specific gas (e.g., H₂S, CO, Cl₂, O₂).
• Verify power supply: 16–32 VDC, 6.2 W max.
• Select mounting option: surface, pipe, or ceiling (accessories sold separately).
• Confirm cable entry type – 5 x 3/4″ NPT is standard.
• For HART communication, ensure your control system supports HART.
• If you need relays or local display, consider other XNX variants.
