Abstract

A method of making a temperature dependent resistor probe for measuring temperature or mass of a flowing medium includes (a) preparation of a support plate of a metallic material; (b) applying a support foil of a temperature resistant plastic material on one side of the support plate; (c) applying a layer of temperature dependent resistive material on the support foil and finishing the resistive layer into a measuring resistor layer; and thereafter, an opening is formed in the support plate in the area below the measuring resistor layer.
