STATUS SCIENTIFIC CONTROLS Installation, Commissioning & Routine Gas Testing FGD10B Pellistor Gas Detector Description The FGD10B is an explosion protected ATEX and IECEx certified fixed gas detector for use in potentially explosive atmospheres. The unit may be optionally fitted with a protective weather guard as shown in the following photograph. -
Page 9: Gas Types
STATUS SCIENTIFIC CONTROLS Installation, Commissioning & Routine Gas Testing FGD10B Pellistor Gas Detector IMPORTANT – When used in hostile environments (e.g. oil platforms where the instrument is exposed to salt spray or diesel) it is recommended that the FGD10B is always fitted with its protective weather guard. -
Page 10: Installation
STATUS SCIENTIFIC CONTROLS Installation, Commissioning & Routine Gas Testing FGD10B Pellistor Gas Detector NSTALLATION It is important that the correct cable and gland types are used when installing the FGD10B in a hazardous location. The cable entry devices and blanking elements of unused apertures shall be of a certified flameproof type, suitable for the conditions of use and correctly installed. -
Page 11: Cable Entries
STATUS SCIENTIFIC CONTROLS Installation, Commissioning & Routine Gas Testing FGD10B Pellistor Gas Detector Cable entries The cable entry threads are 20mm, ½” or ¾” NPT female. The FGD10B enclosure is manufactured from die cast aluminium. Therefore, the use of glands, conduit fittings and blanks made from brass should be avoided because if moisture is present, bi-metallic corrosion may occur due to the chemical reaction between the two materials. -
