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 burning gases into the plant.
The recommended method of determining the oxygen level in a flare stack is to use an analyser fitted with a magneto-dynamic cell, which measures the paramagnetic properties of the gas. Oxygen is paramagnetic where other gases are not, making the Servomex paramagnetic cell, as fitted to the 2200 process analyser, one of the safest and most reliable means of monitoring the presence of oxygen in hazardous situations. Typically, in a flare stack application, alarms are generated by the analysis equipment when the oxygen level exceeds about 1 per cent.

The Servomex 2200 analyser consists of a paramagnetic oxygen measurement transmitters and a separate microprocessor-based control unit capable of accepting inputs from up to six transmitters.
