Title: Carbon dioxide sensor
Inventor: NISHIGUCHI MASASHI
IPC: G01N27/406
Filed: 1990-11-19
Abstract: PURPOSE:To enhance reliability by preventing the erroneous operation and deterioration of a sensor by covering the gas sensing part of a solid electrolyte type carbon dioxide sensor with a housing part having an opening part. CONSTITUTION:The atmosphere coming into contact with a gas sensing part 1 (the atmosphere in a housing part 7) communicates with the outside atmosphere only through an opening part 8. Therefore, an atmosphere to be measured penetrates in the housing part 7 from the opening 8 by diffusion and comes into contact with the sensing part 1 to make it possible to measure the concn. of carbon dioxide. As a result, even when interfering gas is present in the atmosphere to be measured for a short time, the penetration of the interfering gas into the housing part 7 by an air stream or a convection is prevented and the atmosphere to be measured penetrates in the housing part only by diffusion. Therefore, the penetration of the interfering gas into the housing part 7 is suppressed. As mentioned above, the contact of the interfering gas with the sensing part 1 can be suppressed by covering the sensing part 1 with the housing part 7 having the opening part 8 and the effect of the interfering gas can be reduced.
