The Automation division of Siemens Industry (www.siemens.com) has unveiled the latest version of the Ultramat 23 gas analyzer that features open interface architectures with Profibus PA/DP, RS 485 based protocols and ELAN supports to simplify process integration.

With paramagnetic measuring cell, the analyzer records the concentration of oxygen by combining the measuring principle of paramagnetic oxygen with the measurements of a maximum of three infrared-sensitive gases in a single unit.

Supplementing the previous version of the analyzer, which features electrochemical measuring cells instead of paramagnetic cells, the latest version of Ultramat 23 gas analyzer offers a highly sensitive measuring cell. This allows the analyzer to accurately measure low oxygen concentrations within the range of below 0.5 percent. The paramagnetic measurement can also be utilized with dry gases. Using Ultramat 23, process states can be effectively controlled and precisely measured with continued analysis of gas concentrations.

The new Siemens gas analyzer is ideally suited for applications in process controls in steel and cement industries. Moreover, combining Ultramat 23 with an H2S sensor and Ultramat 23 with a paramagnetic measuring cell is ideal for quality control during biomethane production and biogas feeding into commercial gas distribution networks.

The analyzer’s automatic calibration feature with ambient air remarkably reduces maintenance requirements. Remote control and operation of the new Siemens gas analyzer is also possible through Simatic PDM (Process Device Manager) or via Siprom GA.
