A contract was recently awarded by Chubb to protect machinery where hot glue is applied to adhesive tape at a world leading adhesive tape production site. These machines are considered ATEX zone 0 hazards due to the permanent presence of vapors and heat.
The SharpEye 20/20MI Mini IR3 Flame Detector was selected for this application due to the availability of this model with ATEX EExia intrinsically safe zone 0 approval when zener barriers are used. A 0-20mA signal converter was used to convert the mA output from zone 0 to a relay output in the safe area.
The SharpEye 20/20MI is an economical and compact Triple IR (IR3) Flame Detector with the highest immunity to false alarms, in a rugged stainless steel housing. It is available in either general purpose non-Ex approved or intrinsically safe approved (EExia) format.
Spectrex Inc. is a technology leader in optical Flame and Open Path Gas Detection (OPGD). Our patented optical UV/IR and IR3 Flame Detector designs, and pioneering patented Xenon Flash designs in OPGD detectors are now the standard for Oil & Gas projects. A wide range of flame detectors are available, from ultra fast (msec) detection time to high sensitivity hydrocarbon and hydrogen flame detection, alongside the equally large OPGD range that can detect hazardous gases, from flammable hydrocarbons to toxic Ammonia and Hydrogen Sulfide. All Spectrex products can operate in the toughest conditions, from African deserts to Alaskan waters and are fully approved to meet relevant third-party Ex hazardous area, performance and reliability standards to the wide range of application challenges, worldwide.
