Topic “LEL”
(Lower Explosive Limit) Flammability limits, also called flammable limits, or explosive limits give the proportion of combustible gases in a mixture, between which limits this mixture is flammable. Gas mixtures consisting of combustible, oxidizing, and inert gases are only flammable under certain conditions. The lower flammable limit (LFL) (lower explosive limit) describes the leanest mixture that is still flammable, i.e. the mixture with the smallest fraction of combustible gas, while the upper flammable limit (UFL) (upper explosive limit) gives the richest flammable mixture. Increasing the fraction of inert gases in a mixture raises the LFL and decreases UFL.

M2 Series Explosion Proof Gas Transmitters
The RKI M2™ is a state-of-the-art transmitter that can operate as an independent, stand-alone system or as part of a system connected with an analog or digital signal to virtually any controller, PLC, or DCS. Setup procedures are simplified with user friendly push buttons and LCD menus. It utilizes a magnetic wand technique for performing non-intrusive calibration. The M2 provides an automatic zero drift correction feature, which results in more stable readings and reduces the need for adjustments due to sensor aging.
The M2 represents the latest leading edge technology in sensor / transmitters today.
Applications
• Petrochemical plants
• Refineries
• Offshore drilling platforms
• Water & wastewater treatment plants
• Offshore oil rigs
• Pulp & paper mills
S Series Diffusion Sensor and Transmitter
The RKI S-Series gas sensor/transmitters are highly reliable and cost effective basic 4-20 mA transmitters for the detection of common gas hazards. The S-Series transmitters are available for LEL (catalytic), LEL (IR) CH4, LEL (IR) HC, O2, H2S, CO, or CO2 (IR). The electronics are encased inside a potted package to avoid damage from mechanical abuse or corrosion, and this assembly is installed inside an explosion-proof enclosure. All sensors are explosion-proof with flame arrestors and approved for use in hazardous atmospheres. There is also an optional version for oxygen for use in non-hazardous atmospheres.
Indoor or outdoor. Explosion proof for Class I, Div. 1, Groups B, C, and D.
Features
• Explosion proof housing
• Patented water repellent sensor coating
• Available for LEL, H2S, CO, O2 , and ppm HC
• IR sensors available for LEL & CO2
