Mixture potential sensor for detecting e.g. hydrocarbons, in oxygen containing gases, has cover for pressing electrode material into disk, where material is attached to disk by screen printing and by heating till to temperature of sensor

摘要

The sensor has a porous cover (1) for pressing gas-sensitive electrode material (2) consisting of conductive polymer on to a solid electrolyte disk (3), where distributed particles of oxides, mixed oxides or metals are embedded into the polymer. The electrode material is attached to the solid electrolyte disk in a firmly adhered manner by using screen printing and by heating till to operating temperature of the sensor. The solid electrolyte is made from doped zirconium dioxide, sodium super ion conductor or beta-alumina.
