There are three main types of sensors.
Fixed gas detection system on tankers.
Pointgard 2700 s rugged water resistant housing comes.
E each flammable gas detection system must have audible and visual alarms that are actuated at a cargoconcentration that is 30 or less of the lower flammable limit in air of the cargocarried.
F each flammable gas detection system must have an audible and visual alarm for power failure and loss of gas sampling flow.
It is very specific to that type of gas only so care has to be taken to ensure that correct tubes are used for the particular type of gas.
The multi gas analyzer consists of a portable bellows pump and detector tubes.
A fixed gas detection system means that there are more points i e detectors which means higher maintenance more complexity and incremental costs associated with added cabling junction boxes.
Multi gas analyzers are used to detect only targeted gases and vapors.
Catalytic sensors rely on the presence of oxygen to function correctly.
Catalytic infrared and electrochemical.
Vimex gas detection systems the purpose of the vimex gas detection system gds is to detect flammable and toxic gases in pump rooms ballast tanks void spaces air ducts or other areas where explosive or toxic gases may be present.
Our detection systems meet the highest demands concerning scanning cycle time max 30 min for gas detection onboard gas tankers quality for ir and combustible fixed sensors and requirements from various classification societies.
The dräger pointgard 2700 is a self contained gas detection system for the continuous area monitoring of flammable hydrocarbon gases and vapors in ambient air.
