General Information

The compact high-precision oxygen analyzer SGM5T contains the approved calibration- and drift-free ZIROX zirconia measuring cell as well the electronic unit (for cell heating control, flow monitoring, cell signal processing, calculations and signal output, e.g. oxygen concentration, air factor , redox-quotient or H2O/H2-ratio). A microprocessor changes the cell signal to the oxygen concentration according to the NERNST equation. The value is displayed as an analog current signal (option: digital interface RS232, software for measuring value recording and storage is available). In addition, the electronic unit can process and provide the signals of another, optionally integrable sensor (e.g. CO2-, humidity- or pressure sensor with standard interface).

The oxygen analyzer SGM5S was especially developed for measurements in CO2-atmosphere of breweries. It contains additional parts for gas filtering and pressure reduction.  

In the SGM5, the measuring cell is continuously monitored. In case of an error, an alarm signal is generated.

Applications

In many technological processes under protective or inert gases, oxygen traces are disadvantageous for the product properties. Precondition for detection and prevention of problems is the fast and precise measurement of oxygen and the determination of the reducing force of inert gases respectively. Due to the increasing adoption of a quality management system (e.g. ISO 9000), a constant monitoring and documentation of quality parameters becomes more important. The SGM5 provides various options for process optimization (soldering and welding processes, heat treatment of metallic surfaces, microelectronic production, food packing technology). For the monitoring of reducing gases, further parameters (redox-quotient, air factor λ, H2O/H2-ratio or CO2/CO-ratio) can be calculated by special mathematical methods.
