A pressure sensor has a circuit arrangement supported by a sensor body and includes: a first electrical-circuit pattern, having respective tracks made of electrically conductive material deposited on a first face of an electrically insulating material, a second electrical-circuit pattern having respective tracks made of electrically conductive material deposited on a region of the second face of the material, and connection means, which electrically connect the first electrical-circuit pattern to the second electrical-circuit pattern. Tracks of the second electrical-circuit pattern have at least one first track defining a plurality of first pads and one second track defining a plurality of second pads, for connection of a first terminal and of a second terminal of the second circuit component, respectively. The first and second track are prearranged so that the first terminal and the second terminal can be connected to any one of the first pads and the second pads. |

1. A pressure sensor comprising a sensor body made at least in part of electrically insulating material, having a first face and a second face opposite to each other and an axial cavity, the axial cavity being closed at the first face by a corresponding diaphragm portion and having an opening at the second face, the cavity being designed to receive, through the opening thereof, a fluid the pressure of which is to be detected, the pressure sensor also comprising a circuit arrangement supported by the sensor body and including:
a first electrical-circuit pattern, comprising a plurality of respective tracks of an electrically conductive material deposited on the first face, on its side external to the cavity, there being connected to the first electrical-circuit pattern a plurality of first circuit components, amongst which detection means for detecting bending or deformation of the diaphragm portion; a second electrical-circuit pattern, comprising a plurality of respective tracks made of electrically conductive material deposited on a region of the second face that surrounds at least partially the opening of the cavity, there being connected to the second electrical-circuit pattern at least one second circuit component having an active part terminal; connection means, which electrically connect the first electrical-circuit pattern to the second electrical-circuit pattern and that extend at least in an axial direction of the sensor body, wherein the tracks of the second electrical-circuit pattern comprise at least one first track defining a plurality of first pads and at least one second track defining a plurality of second pads, for connection of the first terminal and of the second terminal of the second circuit component, respectively, and wherein the first and the second tracks are prearranged in such a way that the first terminal and the second terminal of the second circuit component are connectable to any of the first pads and to any of the second pads, respectively, and/or to the first pad and to the second pad, respectively, of any of a plurality of pairs of first and second pads. |
