Siemens extends gas analyser functionality for increased plant efficiency

30 August 2011

Increasing operational efficiency is a key priority for plant operators and to help them meet this ongoing goal, Siemens has introduced new functionality to its ULTRAMAT 23 gas analyser.

The Siemens ULTRAMAT 23 has been advanced to include two additional measurement options - a hydrogen sulphide sensor and paramagnetic cell for oxygen gas analysis.

The analyser can now simultaneously measure four gas components using a combination of infra-red and electrochemical cells: methane, carbon dioxide, oxygen and hydrogen sulphide.

Unlike with some devices, the ULTRAMAT 23 measures all gas components simultaneously, removing the need for separate analysers which means operational efficiency is increased and costs reduced.

To further increase operational efficiency, the ULTRAMAT 23 has a menu-guided plain-text display panel which enables engineers to view all data which has been stored – this data then allows for preventative maintenance to reduce plant downtime.

Engineering time throughout the life of the analyser is also greatly reduced, as calibration with gases is only necessary once a year and the device has cleanable sample cells which means they can be reused after contamination instead of having to be replaced.

Bob Lane, process analytics business manager, Siemens Sensors & Communication, said: “The ULTRAMAT 23 is a well established product but these two new additions to our portfolio truly provide a complete solution for plant analysis and, importantly, help increase operational efficiency and reduce maintenance and operating costs.

“The paramagnetic cell for oxygen analysis is a particularly important development as this solution combines the measurement of infrared active gases with the paramagnetic oxygen principle, allowing the measurement of lower concentrations of oxygen and dry gases which many analysers don’t offer.

“While operational efficiency is a key focus, the ULTRAMAT 23 also improves safety as it accurately measures flammable gases – and it can measure lower levels of these compared to other devices on the market.”

Siemens’ ULTRAMAT 23 can be fully integrated into a plant’s control system, enabling remote operation and process control.
