How It Works
How IR Flame Detection Works
IR Flame detectors continuously sample the surrounding atmosphere and respond the moment a hazardous concentration is present, triggering a local and remote alarm before the condition becomes dangerous.
What It Monitors
Continuously samples the ambient air at the installation point, watching for the target gas or hazard to reach a pre-set alarm threshold.
Sensor Response
The sensor reacts to the presence of the hazard with a measurable signal change, which the detector's electronics convert into a concentration reading.
Sensor Technology
Depending on the hazard, the detector may use electrochemical, catalytic (pellistor), infrared (NDIR), PID or solid-state sensing. The technology is selected to suit the specific gas and environment.
Alarm Communication
Once a threshold is crossed, the detector raises a local visual/audible alarm and transmits the event via 4-20mA, relay or Modbus to the control room or SCADA system.
Applications & Risk Areas
Where IR Flame Detectors Are Used
IR Flame Detectors are installed wherever the hazard can accumulate, leak or be generated as part of normal operations. The exact installation areas depend on your site's process and layout.
Oil & Gas Facilities
Process areas, wellheads and pipeline routes where flammable or toxic gases may be present.
Chemical Processing Plants
Reactor, storage and handling areas where process chemicals present a leak or exposure risk.
Power & Utility Plants
Turbine halls, fuel handling and utility areas requiring continuous hazard monitoring.
Water & Wastewater Treatment
Chlorination, dosing and confined treatment areas where toxic gases can accumulate.
Manufacturing & Process Areas
Production lines and process equipment where combustible or toxic byproducts are generated.
Offshore Platforms
Wellhead, process and accommodation modules requiring certified hazardous-area detection.
Storage & Warehousing
Bulk storage, tank farms and warehousing areas holding hazardous or flammable materials.
Confined Spaces & Utility Rooms
Enclosed, poorly ventilated spaces where gas can accumulate quickly and go undetected.
Detector Types
Detector Types & How to Choose
Start by deciding how the detector will be used: permanent area monitoring or portable personal protection. Then confirm the number of gases, target gas, sensor technology, hazardous-area requirements and system integration.
Specifications
Key Features, Specifications & Environmental Suitability
Gas detector selection depends on three factors: the features that support operation, the specifications that match the gas hazard, and the environmental limits that determine reliable field performance. Confirm the exact gas, sensor technology, measuring range, enclosure and output configuration before approving any detector.
Gas detector features determine how operators read gas levels, receive alarms, diagnose faults and connect the detector to a wider safety system.
Gas and Sensor Configuration
Gas detectors support specific combinations of gases and sensor technologies. A detector that supports several sensor technologies does not automatically detect several gases at the same time. The selected sensor module defines the gas, measuring range and unit.
- Electrochemical sensors for oxygen and selected toxic gases
- Catalytic bead or pellistor sensors for combustible gases
- NDIR sensors for carbon dioxide and compatible hydrocarbon gases
- PID sensors for volatile organic compounds
- Semiconductor or MOS sensors for selected gas-leak applications
Local Display and Alarm Indication
A local LED or LCD display shows the gas concentration, alarm condition, sensor status and fault information. Audible alarms, visual beacons and hooter-cum-flasher accessories provide local warning in noisy or high-risk areas.
- Gas concentration, alarm, sensor and fault status on a local display
- Status LEDs for normal, alarm, calibration and system-failure states
- Audible alarms and visual beacons
- Hooter-cum-flasher accessories for noisy or high-risk areas
Diagnostic and Maintenance Functions
Diagnostic features reduce downtime and simplify maintenance, letting teams identify faults before the gas-monitoring point becomes unavailable.
- Sensor fault indication
- Over-range warning
- Calibration-due alert
- Calibration-failure alert
- Open-loop or communication fault
- Sensor-replacement warning
- Test mode for LEDs, relays and outputs
- Replaceable or pluggable sensor modules
Output and System Integration
Gas detectors transmit readings and alarms to gas-detection controllers, PLCs, DCS platforms, SCADA systems, BMS panels and shutdown systems. The selected communication method must match the existing control architecture and alarm philosophy.
- 4–20 mA analogue output
- Relay contacts
- RS-485
- Modbus RTU
- HART
- Local alarm outputs
Calibration and Programming
Calibration confirms that the detector responds correctly to a certified concentration of test gas. Non-intrusive magnetic programming allows technicians to configure alarms, outputs and calibration settings without opening a flameproof enclosure.
- Non-intrusive magnetic programming
- Password protection
- Calibration records
- Stored sensor data for maintenance traceability
Gas detector specifications define whether the product matches the target gas, detection range, hazardous area and control system.
Gas Detected
The specification must name the exact gas or gas category. Terms such as "combustible gas" or "toxic gas" alone do not confirm compatibility with every gas in that category.
- Combustible gases
- Toxic gases
- Oxygen
- Carbon dioxide
- Volatile organic compounds
Measuring Range and Units
The measuring range must match the expected concentration and safety objective. A product configured for ppm monitoring serves a different purpose from a detector configured for %LEL or %V/V monitoring.
- %LEL for combustible gas concentration
- ppm for low-level toxic gas and VOC monitoring
- %V/V or %Vol for oxygen, carbon dioxide and high-concentration gases
- mg/m³ for mass-based concentration measurement
Sensor Technology
Sensor technology controls gas compatibility, response behaviour, maintenance needs and resistance to contaminants. The gas and sensor must be selected together because a suitable enclosure cannot compensate for an unsuitable sensor.
- Target gas
- Measuring range
- Oxygen availability
- Cross-sensitivity
- Sensor-poisoning risk
- Expected humidity
- Operating temperature
- Required service life
Response Time
Response time defines how quickly the detector reaches a specified percentage of the final gas reading after exposure, commonly expressed as T50 or T90. Use the stated response time for the selected gas and sensor configuration, not a general value taken from another model.
- Gas type
- Sensor technology
- Diffusion or pumped sampling
- Filter condition
- Airflow
- Temperature
- Detector placement
Detector Type
The detector format must match the monitoring method. A configurable single-gas detector remains a single-gas detector even when the manufacturer offers several sensor options.
- Fixed: continuous monitoring at permanent locations
- Portable: personal safety, confined-space entry and mobile checks
- Standalone wall-mounted: kitchens, utility rooms and smaller premises
- Multi-gas: multiple sensing channels for simultaneous monitoring
Power and Wiring
Power and wiring requirements affect installation cost and controller compatibility. Confirm voltage, cable type, current consumption, loop resistance and backup-power requirements before installation.
- 24 V DC
- 2-wire loop-powered
- 3-wire
- 4-wire
- Battery-powered
- Wireless communication
Enclosure and IP Rating
The enclosure protects the detector from dust, moisture and mechanical exposure. An IP rating defines protection against dust and water, but it does not certify the detector for an explosive atmosphere.
- Flameproof or explosion-protected enclosure
- Weatherproof enclosure
- Safe-area enclosure
- IP65 / IP66 / IP67 / IP68
Hazardous-Area Certification
Hazardous-area certification confirms suitability for a defined explosive environment. Certification belongs to the exact model and enclosure configuration, not to the product family in general.
- ATEX
- IECEx
- PESO
- SIL 2
- CE
Environmental suitability determines whether the gas detector remains accurate, accessible and serviceable at the installation point.
Operating Temperature
Every detector has a defined operating-temperature range. Select a detector rated for the site's minimum and maximum ambient temperature, including direct sunlight, process heat and seasonal conditions.
Humidity and Condensation
High humidity, condensation and water ingress affect sensors, filters and electrical connections. An IP-rated enclosure protects the electronics, but the sensor opening must still remain exposed to the atmosphere being monitored.
- Relative humidity limit
- Non-condensing requirement
- Outdoor exposure
- Washdown conditions
- Condensation risk
- Cable-gland protection
Dust, Water and Corrosion
Dust, salt, chemicals and corrosive vapours reduce detector life when the enclosure and sensor materials do not match the environment. Marine areas, chemical plants, wastewater facilities and fertiliser plants require specific attention.
- Enclosure material
- Sensor housing
- Protective filters
- Cable glands
- Coatings
- Stainless-steel accessories
Hazardous-Area Conditions
A detector installed in Zone 0, Zone 1 or Zone 2 must carry the appropriate hazardous-area approval. A weatherproof detector is not automatically suitable for a hazardous area, and an explosion-protected detector is not automatically suitable for prolonged water exposure. Both requirements must be checked separately.
Airflow and Detector Placement
Detector placement controls whether leaked gas reaches the sensor. Gas density alone does not determine mounting height because air movement, temperature and leak momentum also influence gas travel.
- Gas density
- Leak source
- Release pressure
- Gas temperature
- Mechanical ventilation
- Natural airflow
- Structural obstructions
- Roof spaces, pits and enclosed pockets
- Access for calibration and maintenance
Vibration and Electromagnetic Conditions
Compressors, pumps, motors and heavy machinery create vibration and electromagnetic interference. Select mounting hardware, cable routing, shielding and enclosure protection that match the installation.
Maintenance Access
The detector must remain accessible for bump testing, calibration, cleaning and sensor replacement. An inaccessible detector increases maintenance time and creates longer periods of unavailable protection.

Installation & Maintenance
Installation, Placement & Maintenance
Correct placement depends on the specific hazard, gas behaviour, site airflow, equipment layout and applicable project or code requirements. There is no single universal mounting distance that applies to every facility. Our engineering team can confirm placement as part of your project.
Installation & Placement
Mounting location, height and orientation are set based on the hazard's density and behaviour, airflow patterns and nearby equipment while avoiding dead zones, direct weather exposure and sources of interference.
Commissioning & Calibration
Every detector is functionally tested and calibrated against a certified reference gas at commissioning, and re-calibrated on a schedule appropriate to the sensor technology and site conditions.
Routine Testing & Maintenance
Periodic bump tests, sensor inspection and preventive maintenance keep the detector within specification between full calibrations, with sensor replacement scheduled around expected service life.
