Title:
ATMOSPHERE SENSING ELEMENT
Document Type and Number:
WIPO Patent Application WO/1981/001880
Kind Code:
A1
Abstract:
An atmosphere sensing element for sensing temperature or the like, comprising a gas-permeable structure (2) or (5) mainly consisting of (Alpha)-MnO2, (Zn-Mn-FeOx), and m Al2O3.nCaO, or a porcelain enamel membrane (9) mainly consisting of (Alpha)-MnO2, (Zn-Mn-FeOx), ((Alpha)-Al2O3.zeolite), and frit, arranged to surround an atmosphere sensing element body (1), (3) or (7). The gas-permeable structure or the porcelain enamel membrane serves to re-combust carbon contained in lampblack or uncombusted gas to prevent deposition of lampblack or carbon on the atmosphere sensing element body (1), (3) or (7) and deterioration of characteristic properties of the atmosphere sensing element body.
