TECHNICAL & REGULATORY FAQs
Engineering FAQs: Fixed Gas Detection
Key compliance, sensor technology, mounting elevation, and calibration answers for plant engineers and safety managers.
What are the mounting elevation rules for fixed gas detectors based on vapor density?
Mounting elevation strictly follows gas vapor density relative to ambient air (Air = 1.0). Heavy gases (LPG: 1.5–2.0, H₂S: 1.19, Chlorine: 2.45, CO₂: 1.52) sink and must be mounted 30 cm to 60 cm above floor level. Lighter-than-air gases (Methane: 0.55, Hydrogen: 0.07, Ammonia: 0.59) rise and must be installed within 30 cm of the ceiling or directly above high-risk leak flanges.
How often do fixed gas transmitters require field calibration and sensor testing?
Electrochemical toxic sensors require calibration verification every 3 to 6 months. Catalytic pellistors require calibration every 3 to 6 months depending on process severity. Non-Dispersive Infrared (NDIR) hydrocarbon transmitters feature optical auto-zeroing and typically require span verification once every 12 months.
