摘要

#CMT# #/CMT# The sensor (1) has a measuring point, which is covered by a passivation unit (10), by which a parameter in a medium (9) to be measured is detected by the measuring point. The material causes an azocoupling, a redox reaction or a complexation reaction. The material comprises an aromatic amine or a mixture of aromatic amines, a zeolite, particularly a silver-containing zeolite. The aromatic amine aniline, comprises an aniline derivative, naphthylamine and a naphthylamine derivative. The aniline derivative comprises a sulfanilic acid. #CMT#USE : #/CMT# Sensor, particularly an absolute pressure sensor. #CMT#ADVANTAGE : #/CMT# The measuring point is covered by a passivation unit, by which a parameter in a medium to be measured is detected by the measuring point, and thus prevents a direct contact of the medium with the measuring point. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an absolute pressure sensor with a passivation unit. 1 : Sensor 3 : Membrane 4 : Substrate 9 : Medium 10 : Passivation unit #CMT#INORGANIC CHEMISTRY : #/CMT# The material is so formed, that it binds or converts sulfur oxides and nitrogen oxides.
