Oxygen analyser Oxystem 600.

Application
Combustion monitoring and control in power plants and other heating systems. Suitable for continuous operation, even under arduous conditions.

Description:
The sensor of the flue gas probe is based on the principle of solid electrolytes (zirconium dioxide). The free oxygen ion movement begins at temperatures of more 500 °C (solid electrolyte potentiometric method).
The sensor is heated. The oxygen concentration is calculated from the cell voltage and the temperature according to Nernst's law.
The analyser consists of a probe and an evaluation unit. The probe is directly immersed into the gas to be measured (in situ). The probe tip should be approximately in the centre of the chimney. The electronic system is equipped with a cable (5 m) with plug which is plugged directly into the probe. The evaluation unit is operated by means of the keypad and the display. The system displays the current oxygen concentration in percent by volume (0-21 % O2 ) and the temperature of the measuring cell.
3 relay outputs (2 x limit control, 1 x alarm) as well as 1 analogue output are available. The system can be set to automatic calibration.
