PRESSURE SENSOR FOR SENSING THE PRESSURE OF FLUID MEDIA, AND PRESSURE SENSOR DEVICE HAVING A PRESSURE SENSOR OF THIS TYPE

摘要

The invention relates to a pressure sensor (1) for sensing the pressure of fluid media, comprising: a housing (10), which has a first pressure port (4), the first pressure port (4) having a first pressure channel (14), to which a first pressure (P1) can be applied, and a second pressure port (5) separated from the first pressure port (4), the second pressure port (5) having a second pressure channel (15), to which a second pressure (P2) can be applied; a first pressure-sensing device (41), which is designed to sense the first pressure present at the first pressure port (4) and to output a first electrical signal (S1), which represents the first pressure (P1) or a pressure difference between the first pressure (P1) and a reference pressure (P3); and a second pressure-sensing device (42), which is designed to sense the second pressure (P2) present at the second pressure port (5) and to output a second electrical signal (S2), which represents the second pressure (P2) or a pressure difference between the second pressure (P2) and a reference pressure (P3). According to the invention, the pressure sensor (1) additionally comprises a third pressure-sensing device (43), which is designed to sense the first pressure (P1) present at the first pressure port (4) and to output a third electrical signal (S3), which represents the first pressure (P1) or a pressure difference between the first pressure (P1) and a reference pressure (P3), and a fourth pressure-sensing device (44), which is designed to sense the second pressure (P2) present at the second pressure port (5) and to output a fourth electrical signal (S4), which represents the second pressure (P2) or a pressure difference between the second pressure (P2) and a reference pressure (P3).
