REGENERIERBARE RAUCHGASANALYSENSONDE

摘要

Solid-electrolyte analysis probe for determining the residual quantity of oxygen in flue gas in the high-temperature range and which allows regeneration at low cost, without special knowledge and special tools. The sensor is constructed from detachable functional units comprising a probe body 8, protective condensation tube 4 and solid electrolyte tube which is closed at one end. The probe body 8 includes all necessary supporting units 10, 12 for the other components, the cold end assembly 21, 22, and connections for the sensor electrodes. The protective condensation tube 4 has gas inlets 5 and indents 6 which are engaged by lugs 9 mounted on support 8. The sensor tube 1 is located within a protective tube and contains powder electrodes 2. The sensor tube connects to the main probe body by a ball and socket joint and is replaceable with its protective tube. Detachable connecting elements (10, 12) are provided between the functional units. <IMAGE>
