High-Precision Oxygen measuring Device SGM5

General Information

The compact high-precision measuring device SGM5T contains the approved calibration- and drift-free ZIROX® zirconia measuring cell as well the process electronic (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 the NERNST equation. The value will be shown at the display and output as analog current signal (Option: digital interface RS232, software for measuring value recording and storage is deliverable) Additionally the electronic can process and output the signals of a further, optional integrable sensor (e.g. CO2-, humidity- or pressure sensor with standard interface).

In the SGM5 the measuring cell will be monitored simultaneously. In the case of error a alarm signal will be generated.

Applications

In many technological processes under protective or inert gases oxygen traces are nonconstructively for the product properties. Precondition for detection and prevention of problems is the fast and precious measurement of oxygen respectively the determination of the reducing force of inert gases. By progressive introduction of quality assurance systems, e.g. according to ISO 9000, a constant monitoring and documentation of quality parameters becomes more important. For it with the SGM5T the user get several possibilities 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 , H2O/H2-Ratio or CO2/CO-Ratio) can be calculated by special mathematical methods.
