| Oxygen-sensor for O2 measurements
in gases Oxygen-sensor with screw-in thread for air-conditioning-plants, air-cleaner,
oxygen-rectifiers, greenhouses, oxygen-incubators, breathing apparatus, artificial
respiration instruments. The oxygen-sensor includes a lead-oxygen-cell, a lead-anode and a
gold-cathode under use of a special acid-electrolyte. The oxygen-molecules of the
gas-mixture exude through a non-porous teflon-membrane into the electro-chemical cell and
are there absorbed by the gold-electrode. The current flow between the electrodes is
proportional to the oxygen-concentration in the gas-mixture to be measured. The signals
are measured as voltage drop over the resistance and the NTC for the temperature
compensation. The modification of the output-voltage is proportional to the concentration
of the oxygen.
