Beschreibung
Zusammenfassung:	A sensor element includes a substrate having a coating on a portion of the substrate. The coating is applied to the substrate by dipping the portion of the substrate into a slurry which includes a pulverized mineral and water, extracting the substrate from the slurry in a direction along an axis, drying the coated substrate, and firing the coated substrate so as to promote densification of the mineral and adhesion of the mineral to the substrate. The coating after firing has a minimum thickness of about 100 microns at every location around the periphery of a cross section through the substrate taken in a plane normal to the axis. A method for making a coated sensor element is also disclosed.
