Frequently Asked Questions (FAQ)

• Does this unit come with a sensor?
  • No. It is a transmitter only – you need to buy a separate mV sensor.
• What communication protocols are supported?
  • Standard HART, optional Modbus RTU, or FOUNDATION Fieldbus.
• Can I add relays for alarm control?
  • Yes, but only if you choose the relay option instead of Modbus or Fieldbus.
• What is the operating temperature range?
  • Transmitter: ‑40 to +65 °C. Check the sensor’s data sheet for its limit.
• How do I configure it without opening the enclosure?
  • Use the magnetic wand on the backlit LCD – no tools needed.
• What is the warranty and shipping time?
  • 12‑month warranty. We dispatch within 12‑24 hours via FedEx, UPS, or DHL.

Selection Guide

• Choose XNX‑AMAV‑NHNNN if you need a versatile transmitter for multiple sensor types.
• For propane / hydrocarbon LEL, see XNX‑AMAV‑NNIF1 (comes with IR sensor).
• For CO₂ 0‑5% vol, pick XNX‑AMAV‑NNIC1.
• For stainless steel housing, order the SS316 version.
