Answer 7 questions on your application to get advice about the best SENSE-WARE flame detector for your application. The detector with the highest score has its score displayed in green. Less suitable detectors are displayed in amber. If you want to detect burning metals or a detector is not suitable for the application the score will be displayed in red.
This selection tool is for indication purposes. If you have any questions please contact your supplier regarding your application.
Once completed, print this sheet and send it to your supplier if you need more information.+

Different technologies react differently through inhibitors that absorb radiation and react differently to potential noise sources.
UV sensors need more maintenance with regards to contamination and potential noise sources when mounted outdoors. UVIR flame detectors have better avoidance of noise sources. IR3 flame detectors are less affected by contamination. |

If you have multiple risks (fuels) then select the primary risk for information and select the secondary risk separately. Do call your supplier for advice.
Solids and liquids generally produce more smoke than gaseous fuels. Different fuels emit different energy and wavelengths. Most vapors and smoke absorb UV radiation. Burning metals are hard to detect.

Different fuels require different technologies for optimal flame detection.
Heavier hydrocarbons tend to burn more dirty. Light hydrocarbons burn cleanly. Non Hydrocarbons emit in different wavelengths expected from the fuel or the local environment. |

Some contamination effects UV sensors more than IR sensors.
A salt layer on the detector window absorbs water during damp conditions; this is an inhibitor for IR sensors. Oil, oil mist and grease absorb UV radiation. |

Potential noise influences of the surrounding area. Some are false stimuli sources, others are inhibitors.
Your plant may have noise sources but your neighbors may cause nuisance alarms as well. Outdoor arc welding may set of UV flame detectors indoors through doors and open windows. Indoor chopped/modulated heat sources may influence flame detectors as inhibitors (IR3) or as a false alarm stimulus (UV/IR). Hot combustian engines exhausts may cause IR3 Flame detectors to alarm. |

Multi IR Flame detectors are often able to detect smaller fires at the same distance as UV or UV/IR Flame detectors.
The UV and UVIR flame detector can detect a 30 x 30 cm (1 sqft) n-Heptane fire at 23 meters (75 ft). The IR3 is able to detect the same fire at, at least 35m meters (115 ft). However, UV and UVIR technology offers detection of many other fuels and especially gases. |
