The latest Servomex process oxygen analyser, the 2200, enables companies in the petroleum and gas industries to analyse the oxygen content of gas close to the burners of flare stacks, while installing the actual gas analyser in a remote control room.
Monitoring the oxygen at the burner prevents a potentially explosive mixture of flammable gas and oxygen building up, eliminating the risk of it igniting and causing a flash-back of burn gases into the plant.
The analyser consists of paramagnetic oxygen measurement transmitters and a separate microprocessor-based control unit capable of accepting inputs from up to six transmitters.
The unit provides digital data communications to production control computers.
Since the analyser provides a physical measurement, there are no chemicals or electrolyte to replace and the maintenance requirement is very low. The 2200 transmitter is certified for use in ATEX category 2 areas and the 2200 control units can be used in ATEX category 2 or 3 areas without the need for purging.
