Abstract
A gas-analysis probe is provided, the sensor of which is formed by a concentration pile. The electric signal supplied by the sensor is picked up by means of at least two metal rods which are brazed to the sensor by thermocompression on thin filler-metal layers. The connecting lead-outs are isolated in pure-alumina sheaths maintained in place in a ceramic body by a hardened liquid ceramic filling. A spring absorbs the differences in expansion and fins on the metal casing remove the heat. A perforated cap protects the sensor.
