INFRARED GAS DETECTION |gas detection|combustible gas detectors|hazardous gas detection|gas leak detection instruments Infrared Gas Detection Equipment: Began in the early 1970s when Acme was the first to adapt instrumentation-style equipment to the building market. Acme's infrared gas detection equipment is designed to control ventilation systems in buildings, most notably through carbon monoxide CO gas detection in underground parking garages. The infrared gas detection systems have three benefits: they provide air quality control; assure safety in environments where dangerous gases are present; and, conserve electricity because the ventilation equipment runs only when required. Other gases include: CO 2 for indoor air quality; diesel fumes detection for bus and truck terminals and unloading areas; Volatile Organic Compounds VOC for numerous industrial and office applications; R-123 refrigerant detection; and, O 2 deficiency detection.Infrared gas detection has been commonly used for either finding gas presence or measuring the gas concentration levels in a particular environment. The very foundation of infrared gas detection is based on the premise that gases use what is called selective absorption of infrared radiation. Infrared gas detection sensors generally comprise one or more radiation sources, such as thermal radiators, one or more absorption sections, wavelength-selecting elements and one or more radiation detectors, which convert the optical signal into an electrical measurement signal. CO Metal Oxide Semiconductor MOS sensors shall have a life expectancy of 5 years. CO2 Infrared gas detection analyzers shall have a life expectancy of 10 years. NO2 and other Electrochemical Cell sensors shall have a life expectancy of two years. Combustible Gas catalytic bead sensors shall be explosion-proof and shall have a life expectancy of four years. The DG-EN is usually installed in bus and truck terminals or maintenance facilities, package distribution warehouses and building loading docks where Diesel fumes pose a threat to indoor air quality. In order to protect the sensor from the Respirable Combustible Dust RCD present in Diesel fumes, Acme uses an air pump to draw the sample to the detection unit from the space, where it is filtered and passed to a solid-state infrared gas detection CO2 analyzer or an electrochemical NO2 analyzer. Both CO2 and NO2 are acceptable surrogates for the determination of overall Diesel pollution in the space, according to research done by the U.S. Bureau of Mines and CANMET.
