Searchline Excel

QRAE 3
XNX transmiter

Searchline Excel is the best-selling infrared beam detector on the market, and it is apllied by users around the world. First introduced in 1998, it has become the standard in the beam gas detection segment with constant upgrades and improvements. It is completely immune to the effects of solar radiation and other sources of radiation. It has a built-in double filter that compensates for the effects of moisture and rain and thus allows the detector to work in all climatic conditions.

Flammable group of gases (Hydrocarbons)

Hydrocarbons

They occur in practically every segment of life. The most famous representative is natural gas (methane, CH4), and the combinations of carbon and hydrogen molecules are practically unlimited. We use them as energy sources in all endothermic processes and in almost all industries (chemical, petroleum, pharmaceutical, petrochemical). The biggest problem is their flammability and explosiveness, and for the most part, toxicity. They are one of the biggest risks in all industries. Flammability directly depends on their concentration in the air mixture and ranges between LEL - Lower Explosive Limit and UEL - Upper Explosive Limit. At concentrations of 4.4% to 17% by volume of methane in the air, the spark causes an explosion, so 4.4% v / v CH4 = 100% LEL.

The standard limits of alarm settings within the EU are Low = 10% LEL, High = 20% LEL
