UV/IRS Ultraviolet/Infrared Flame Detector


Net Safety’s UV/IRS ( Ultra-violet/Infrared ) flame detector delivers exceptional performance with many distinct functions and features. Two precise spectrums of radiation must be recognized and confirmed by highly tuned sensors for the UV/IRS to initiate a fire condition. This accurate and reliable flame monitoring technology combined with immunity to arc welding, hot body radiation, lightning and sunlight greatly reduces costly false alarms while providing critical safety performance to your site and personnel.

Enclosed in a rugged, explosion-proof housing, the Net Safety UV/IRS flame detector uses the latest in modular microprocessor and Ultraviolet/Infrared sensor technology — delivering accurate and reliable monitoring for hydrocarbon based fires. It’s capable of stand-alone operation or can be connected to a variety of networked safety systems to create a dependable fire monitoring system.

The UV/IRS Flame Detector has many unique features which make it one of the industries best: an extra wide field of view — up to 120 degrees; user defined sensitivity and time delay settings can be completed in the field with no special tools required; one of the lowest power consumption levels and widest voltage range available on the market; plus the option of a separated HART communication interface at ground level.

Net Safety has engineered a superior UV/IR flame detector that is simple to operate and maintain while delivering all the security and performance required for high-risk, industrial installations!
