We focus on the manufacturing of planar oxygen sensors by screen printing multiple layers of sensing, protective, insulating, adhesive, and conductive materials (including platinum heater and electrical leads) on a number of ceramic layers. These layers are stacked accordingly, pressed together and cut into individual elements before firing at a temperature over 1400 oC. The sensing elements are mechanically very strong and hard.

 

Each sensor element is packaged into the stainless steel housing with a protection cover of the sensing area (which will be exposed to the exhaust gas), sealing in at the middle section, ceramic supports at both sides of the sealing, connector to the wirings. An example of a cross section of finished sensor is shown below:
