摘要

A) the production of a sensor exhibits a high electrical of stability in time, in particular in installations for drying, meteorology, in the medicine or the like. / p & & p & b) process for manufacturing characterizes in that on a substrate of pure aluminium 3 is formed a layer of aluminum metahydroxide 4 by hydration in water boiling redistilled for 5 to 60 minutes, a layer that is passivated by imbibing in an aqueous solution of sodium acid phosphate of a concentration of 0,01 to 2 moles, at a temperature of 35 at 100 c. for 5 to 60 minutes. / p & & p & c) the invention relates to a method of manufacture of a sensor exhibits a high electrical of stability in time, in particular in installations for drying, meteorology, in the medicine or the like.
