SGOES Infrared Combustible Gas Detector
820-0006 Operating Manual
Page 12
Density of Detected
Gas If the target gas is heavier than air, the sensor should be located within 4 feet of grade.
Heavier than air gases will tend to settle in low-lying areas. For gases lighter than air, sensor
placement should be 4-8 feet above grade in open areas or in pitched areas of enclosed
spaces.
Probable Leak
Sources Leak sources include flanges, valves, tubing and connections of the sealed type where seals
may either fail or wear. All potential leak sources and SGOES mounting locations are best
determined by facility engineers with experience in similar processes.
Ventilation &
Prevailing Winds Normal ventilation or prevailing wind must be considered for locating SGOES detectors.
Personnel Exposure Consideration should be given to placement of detectors in areas where personnel may
be exposed. Account for ventilation, wind direction and potential gas cloud size when
determining the number and location of gas detectors.
Maintenance Access
Consideration should be given to providing easy access for maintenance personnel.
SGOES location should also take into account the proximity to contaminants that may
foul or obscure the SGOES optics.
