Fail-safe oxygen measuring systems

The oxygen measuring systems from J. Dittrich Elektronic contain a dynamic zirconium dioxide sensor. They determine the oxygen concentration directly in the gas mixture, monitor their own function during operation, signal malfunctions in the hard- and software, can be calibrated without personnel or reference gas in atmospheric air and, hence, are fail-safe. The measuring process is linear in a measuring range from 0.1 to 100 vol%. As they determine the absolute oxygen content, they measure exact, even in extreme climates. In practice, therefore, oxygen measuring systems from J. Dittrich Elektronic are used above all to regulate the residual oxygen in the exhaust gas from furnaces, to regulate ventilation in large industrial composting heaps or for indoor air monitoring. The designs are adapted to the specific applications (insertion probe, wall mounted system and others).
