Siemens expands compact gas analyzer with paramagnetic oxygen measurement

A new version of the Ultramat 23 gas analyzer from the Siemens Industry Automation Division records the concentration of oxygen using a paramagnetic measuring cell. The analyzer combines the measurement of up to three infrared-sensitive gases and the paramagnetic oxygen measuring principle in one unit.

The new version of the Ultramat 23 gas analyzer with a paramagnetic cell supplements the previous versions of the analyzer with electrochemical measuring cells. The most significant advantage of the paramagnetic measuring cell is its high sensitivity. It is now possible to reliably measure low oxygen concentrations in the range of less than 0.5 percent. In addition, the paramagnetic measurement can also be used with dry gases. Continuous analysis of gas concentrations using the Ultramat 23 means that process states can be precisely measured and effectively controlled. Typical applications for the new Siemens gas analyzer include process controls in the cement and steel industries. Furthermore, the combination of Ultramat 23 with a paramagnetic measuring cell and Ultramat 23 with an H2S sensor is suitable for quality control during the production of biomethane and feeding of biogas into commercial gas distribution networks.


The automatic calibration function with ambient air significantly reduces the maintenance requirements. The open interface architecture with RS 485 based protocols, Profibus PA/DP, and ELAN supports and simplifies process integration. Furthermore, remote operation and control of the analyzer is possible via Siprom GA or Simatic PDM (Process Device Manager).
