Hazardous areas generally require 24/7 protection from explosive risks. Accurate and reliable industrial flame monitoring is typically installed to mitigate these risks. While flame detectors are an essential layer of protection, a false alarm can be costly and play havoc with operations. Making sure you have the right type of flame detector installed can ease your concerns.
We Have You Covered for Your Flame Detection Requirements
False Alarm Rejection
False alarms are more than just a nuisance — they are both a productivity and cost issue. Our flame detectors are designed to measure the emitted radiant energy at specific light wavelengths, allowing them to distinguish between real flames and false alarm sources that commonly exist at industrial worksites.
Wide Field of View
A flame detector’s Field of View (FoV) helps define the area coverage per device. A flame detector with a large field of view can take in a broader scene, which may help reduce the number of flame detectors required for certain installations. Use our FL500 UV/IR Simulator to see how a flame detector’s FoV is affected by fuel source and sensitivity settings.
Fast Response Time
Seconds count. The faster that a flame detector can alarm to a fire, the more effective the resulting mitigation and notification actions will be for protection of people and assets.
Long Flame Detector Range
A longer detection distance could reduce the amount of optical flame detectors required to cover an area which lowers both installation and maintenance costs. Our FL4000H MSIR flame detector can cover distances up to 230 ft!
Safety Integrity Self-Check
A self-check system ensures that the optical path is clear, the detectors are functioning, and the electronic circuitry is operational providing for worry-free operation. Our exclusive TL105 Test Lamp allows our flame detectors to be easily and routinely tested without the associated risk of an open flame.
Remote Monitoring & Notification
On-site or in the cloud, MSA’s Infrastructure Connectivity Solutions enable the sharing of critical operational data 24/7 through our safe and secure FieldServer gateways and our cloud-based services—MSA Grid FieldVEU and MSA FieldServer Manager.
Flame Detector Technologies
There are two primary technologies used for detecting flames – UV/IR and MSIR. They are all based on line-of-sight detection of radiation emitted in the UV (ultraviolet) and/or IR (infrared) spectral bands by flames.
UV/IR flame detectors
Principle of Operation: a UV optical sensor is integrated with an IR sensor creating a dual band detector which is sensitive to both ultraviolet and infrared radiation emitted by a flame.
- Operate at fast speed
- Suited for both indoor and outdoor use up to 90 feet (depending on the fuel type)
- Affected by thick smoke
Principle of Operation: use multiple infrared spectral regions to further improve differentiation of flame sources from non-flame background radiation. (Earlier models used Triple IR sensors whereas the FL4000H uses four sensors.)
- Operate at moderate speed
- Typically cover longer detection ranges than UV/IR
- Well suited to locations where combustion sources produce particularly smoky fires
- Exhibit relatively high immunity to infrared radiation (arc welding, lightning, sunlight and other hot objects)
- Cost tends to be higher relative to UV/IR flame detectors.
