Abstract

PURPOSE: To achieve accurate detection and measurement of even carbon monoxide of low density with limited calorific value but with a higher sensitivity by separating temperature measuring resistance section from heat source section of the contact combustion type gas detection element.
CONSTITUTION: Pt wire or Ni wire A insulated is closely wound outside an alumina tube 4 of proper dimensions, for example. A heatproof insulating paint such as alumina cement is applied as evenly and thinly as possible to fasten the Pt coil or the Ni coil. After dried, the alumina cement is sintered. Ni-Cr heaters 3 are each inserted into the alumina tubes 4 arranged one set per two and fastened on the stem, and hence assembled as a sensor. After mixed with an inorganic adhesive and rendered into fine powder, highly pure palladium oxide is applied over the surface of one Pt or Ni wire A alumina-processed with a fine brush or the like and solidified by drying to form an active catalyst layer 1, while the other Pt or Ni coil A forms an alumina layer 2 of the compensation section. Thus, a detection element is obtained.
