Page 4: Acetylene
E2670-LEL Rev 15.03.2023 Acetylene A colorless flammable gas, lighter than air. Mixtures with air are explosive. It results from the interaction of calcium carbide with water. In industrial production, acetylene is mainly manufactured by the pyrolysis of light hydrocarbons. Acetylene is widely used for welding and cutting of metals. The usage of acetylene as a feedstock in the chemical industry declines due to cost and environmental considerations. -
Page 5: Butane
E2670-LEL Rev 15.03.2023 Butane A colorless flammable gas that is heavier than air. The term “butane” is used for any of two structural isomers (n-butane or iso-butane, with unbranched and branched-chain respectively) or for their mixture. Occurs in light petroleum fractions. Butane is used mainly as a fuel and as a feedstock in organic synthesis. -
Page 6: Hexane
E2670-LEL Rev 15.03.2023 Hexane A colorless flammable gas that is heavier than air. Hexane is a constituent component of gasoline. It is widely used in solvents as it is cheap, relatively safe and largely unreactive. It is also used as an industrial cleaner and degreaser and is an ingredient in many consumer products. -
Page 7: Hydrogen
E2670-LEL Rev 15.03.2023 Hydrogen A colorless, odorless, flammable gas that is much lighter than air. Mixtures with air are explosive. Results from the interaction of acids, bases, and water with active metals and from the electrolysis of aqueous solutions. In industrial production, the main source of hydrogen is hydrocarbons. -
Page 8: Methane
E2670-LEL Rev 15.03.2023 Methane A colorless flammable gas, the main component of natural gas, marsh gases. Methane results from bacterial decomposition of plant and animal matter (landfill gas). Methane is widely used as a fuel and chemical feedstock. Synonyms: Marsh Gas, Natural Gas, Carbon tetrahydride, Hydrogen carbide. Chemical formula Molar weight Relative gas density (to air) -
Page 9: Octane
E2670-LEL Rev 15.03.2023 Octane A colorless flammable gas that is heavier than air. Octane is a component of gasoline (petrol). Chemical formula Molar weight 114.23 Relative gas density (to air) 3.86 Conversion* 1 ppm = 4.67 mg/m3 Boiling point 125.6 °C Low explosive limit (LEL), % vol. -
Page 10: Propane
E2670-LEL Rev 15.03.2023 Propane A colorless flammable gas that is heavier than air. It occurs in light petroleum fractions. Propane is used mainly as a fuel and as a feedstock in organic synthesis. It is applied also as a propellant in aerosol sprays and may be used as an ozone-friendly refrigerant. Mixtures of propane with butane and other hydrocarbons are referred to as LPG (liquefied petroleum gas). -

Page 13: Product Description
E2670-LEL Rev 15.03.2023 Product description E2670 is a series of flameproof gas detectors-transmitters intended for operation in safe zones and ATEX Zones 2 and 22. E2670 series devices are based on the PluraSens® multifunctional platform and provide all its features. The instruments utilize gas sensors of various types with excellent repeatability, stability, and long lifetime. -
Page 14: Operating Conditions
E2670-LEL Rev 15.03.2023 Operating conditions The device should be used in a basic electromagnetic environment, where the latter is defined in EN 61326-1. Avoid strong mechanical shock and vibrations. Although E2670 series devices are suitable for use in the presence of flammable dust, special precautions should be taken when operating in a dusty environment. - Page 15 E2670-LEL Rev 15.03.2023 The device is fixed on the wall using two fixing holes located outside the sealed area of the device (see dimensional drawing). Unscrew four lid screws and detach the lid from the detector. Fix the detector on the wall and earth the enclosure using an earthing terminal on the side of the device.
