Gas Monitoring System

• Used to monitor gas leakages
• Simple operation
• Low maintenance

• User-friendly
• Excellent ability to detect leakage of gas
• Used in food processing, chemical and pharmaceutical companies

The gas detector in intended to be used in an ambience where there is possibility of presence of Hydrocarbon gases. The detector must be explosion proof for continuous monitoring of combustible gases and vapor in the ambient air. The transmitter must be reliable and designed for harsh environment.

Principle: Infra red Sensor with double compensated beam i.e. two beams one acting as reference beam and another as active signal beam for unrivalled signal stability and no interference from environmental influence. Non imaging optics, compensation for temperature & ageing.

Measuring Gases: Flammable gases and vapors.(N.G, LPG & Condensate). The central controller. HART digital signal: Present.

Classifications: Class I, Div. I, Group A,B,C & D, ATEX II, 2GD, EEx d IIC

• Alkanes or saturated hydrocarbons such as methane,ethane, propane, butane, pentane, hexane, and heptane, etc.
• Cycloalkanes such as cyclopropane, cyclohexane, methyl cyclohexane.
• Alkenes or unsaturated hydrocarbons such as ethylene,propylene, butene, pentene, hexene, octene, etc. Acetylene has absorption at 3.1 microns which is not detectable.
• Cycloalkenes such as cyclohexene and pinene.
• Aromatics such as benzene, toluene, and xylene.
• Alcohols such as methanol, ethanol, propanol, and allyl alcohol.
• Amines such as dimethyl amine, trimethyl amine,butanamine, cyclopropanamine, and pyridines.
• Ethers such as dimethyl ether, ethyl ether, n-propyl ether, methylvinyl ether, vinyl ether, ethylene oxide,tetrahydrofuran, furan, and 1,4-dioxane.
• Ketones such as acetone, methyl ethyl ketone,pentanone, methyl isobutyl ketone and heptanone.
• Aldehydes that have a central wavelength mostly at the 3.55 micron region and generally have a weak detection signal at 3.4 microns.Carbon dioxide at 4.3 microns and carbon monoxide at 4.6 microns have very little interference by other gases.
