ABSTRACT:
A sensor for thermal mass flowmeters is described herein. The sensor includes a plate-shaped, thin-film resistor and a cylindrical holder into which the resistor is fastened. In order to fasten the thin-film resistor in a mechanically stable manner, the end surface of the holder is provided with a pocket hole which closely matches the cross section of the thin-film resistor. The thin-film resistor is suitably inserted into this pocket hole and fastened therein with an adhesive agent.
