Expert Review – Manager’s Insight

Reliable methane detection for critical areas. The XNX platform stands out because of its modular design. The MPD IR sensor offers long-term stability, even in humid or dusty conditions. HART communication makes troubleshooting simpler. For plant managers, this means less downtime and lower maintenance costs. The aluminium housing withstands corrosion and mechanical stress. I highly recommend this unit for oil & gas, wastewater, and chemical plants.

Ideal Applications & Compatible Equipment

• Oil & gas platforms – LEL monitoring for leak detection
• Chemical processing plants – solvent and methane areas
• Wastewater treatment – digester gas monitoring
• Power generation – turbine and fuel gas areas
• Refrigerated storage – methane/fuel gas safety
• Compatible with Honeywell control panels, Modbus gateways, and third-party DCS.

Frequently Asked Questions (FAQ)

• What is the sensor range for methane?
  0–100% LEL (equivalent to 0–5% v/v).
• Can I use this detector with a non-HART system?
  Yes, the 4-20mA output works with any standard analog input.
• Is the sensor replaceable in the field?
  Yes, the MPD IR sensor is a plug-in replacement, no re-wiring required.
• What cable entry size does this model accept?
  Four M25 entries (metric).
• Does it include a display?
  This variant does not have a local display; use HART or a handheld communicator.
• What is the operating temperature limit?
  -40 °C to +65 °C (ambient).
• How often should I calibrate?
  Recommended every 6 months, depending on application severity.

Experienced User Tips & Selection Guide

• Calibration gas concentration: Use 50% LEL methane for best span accuracy.
• Wiring distance: For runs >300m, use a 24 VDC supply and thicker gauge cable.
• Sensor protection: Install the optional splash guard if water spray is possible.
• Selection advice: Choose this model for methane only. For multi-gas, consider other XNX personalities.
• Environmental note: The IR sensor is immune to common poisons like H₂S and silicones.
• Start-up delay: Allow 60 seconds for sensor stabilisation after power-on.
