41.2 ConstructionA complete GD10P Gas Detector consists of the following:An external gas measuring path where gas is measured by monitoringabsorption of IR radiation. A weather protection enclosure is mountedaround the measuring path to protect the optical surfaces from rainand dust and other contaminants.An optoelectronic unit, which generates IR radiation to the gasmeasuring path, measures the reflected IR radiation from the gasmeasuring path and calculates the gas concentration. This unit isenclosed by an EExd certified housing.A terminal compartment with cable entry and mini-terminals forelectrical connection. The compartment is protected by a cover and isEExe certified.1.3 Application areasThe GD10P is primarily designed for detection of hydrocarbon or CO 2gases in hazardous areas on offshore platforms and petrochemicalplants, but it can also be used in a variety of other applications.For retrofit applications, a bridge interface is available allowing thedetector to be connected directly to catalytic systems, using theexisting cabling and control modules.With the Sample Flow Housing mounted, the detector can be used inaspirator systems or process monitor and control systems.The GD10P is housed in a compact stainless steel enclosure, which iscertified flame-proof, meeting the requirements of EN 50018.
