Abstract
A method of manufacturing a self-supporting measuring probe suitable for application in a highly corrosive environment such as for example in a muffler or suction channel of a motor vehicle, is disclosed. The probe is provided with a protective foil which is applicable on a rigid substrate carrying the measuring layers, by means of a heat sealing process in which heat and pressure are simultaneously applied on the foil. In a preferred embodiment, the edges of the foil are fused to the substrate by a laser beam.
