Patent ID: 8152980

Claim:
A high temperature potentiometric industrial sensor comprising: a first platinum electrode coupled to a top surface of a first yttria stabilized tetragonal zirconia (YTZP) electrolyte wafer; a second platinum electrode having a distal side externally disposed relative to a sealed chamber and a proximal side internally disposed relative to the sealed chamber; said sealed chamber comprising: a housing having a seal layer enclosing an internal reference material within the sealed chamber and forming a single chamber containing the internal reference material, the housing including said first platinum electrode disposed on the distal side to a bottom surface of said first yttria stabilized tetragonal zirconia (YTZP) electrolyte wafer, a cylindrical ring-like La x Sr y Al z Mn 1−z O 3 (LSAM) electronically conductive electrode layer whose stoichiometry ranges from x+y≦1 and 0.3≦z≦0.9 and is further coupled to the second platinum electrode wherein said second platinum electrode spans a gap of the cylindrical ring-like LSAM electrode layer, a second yttria stabilized tetragonal zirconia (YTZP) solid, cylindrical ring-like component coupled to the LSAM electrode layer and a third YTZP base layer coupled to said second YTZP cylindrical ring-like layer by a bond layer.
