Abstract

A method of manufacturing a sensor set-up for determining at least one pressure of a fluid medium. The method includes: a) providing a blank of a sensor set-up including at least one pressure connection, the pressure connection including at least one pressure deformation element made up of at least one material suitable for induction; b) positioning at least one glass element onto a surface of the pressure deformation element; c) measuring at least one temperature of the pressure deformation element using at least one pyrometer; d) inducing a voltage in the pressure deformation element using at least one inductor in such a manner, that the glass element melts and a glass layer forms on the pressure deformation element; e) positioning a sensor element onto the glass layer in such a manner, that an integral bond forms between the sensor element and the glass layer.
