Abstract

Sensor, en especial sensor de flujo de masa, con una capa dieléctrica de soporte (21), sobre la que está colocada una capa (23) que contiene platino y está estructurada formando un elemento de resistencia, en el que por lo menos una superficie de la capa (23) que contiene platino tiene al menos por zonas un recubrimiento con una capa adhesiva adicional (22, 24), caracterizado porque la capa adhesiva (22, 24) consta de silicio y tiene un grosor de entre 0,5 nm y 2,4 nm.
