LNG Plant Flame Detector Multispectrum IR Flame Detector DET-TRONICS X3301 Fire Detection Sensor Price

DET-TRONICS X3301 Multispectrum IR Flame Detector

Product Overview

The X3301 is Det-Tronics’ flagship multispectrum infrared flame detector. It uses three IR bands and advanced signal processing to reliably detect hydrocarbon fires while ignoring false alarm sources like arc welding, hot CO₂ emissions, sunlight and artificial lights. It is one of the most installed detectors in high-hazard oil & gas facilities due to its long range and fast response.

Application Industry

  • Offshore oil & gas platforms
  • Refineries & petrochemical plants
  • LNG liquefaction & regasification
  • Compressor stations & gas plants
  • Aircraft hangars & turbine enclosures

Common Problems & Solutions

  • False alarms from welding or flares → Multispectrum algorithm + patented processing rejects them
  • Detection delay in large areas → 210 ft on-axis range with fast T90
  • Fog or rain interference → Heated optics option available

Replacement Models

  • Previous X3301 generations (pre-firmware updates)
  • X3302 (hydrogen-specific version)
  • Single IR detectors (X3800 / X3300)
