| Zusammenfassung: | A pressure sensor is disclosed. The pressure sensor includes a pressure sensor unit provided with a pressure detecting element configured to receive a drive voltage from a control substrate and electrically send a pressure detection signal to the control substrate so as to detect a pressure of fluid, and a plurality of electric wires connected to the pressure detecting element so as to supply the drive voltage and drawn to the outside so as to send the pressure detection signal. The pressure sensor may also include a relay substrate connected to the plurality of electric wires and having a converting circuit mounted thereon. The converting circuit converts either or both of the drive voltage supplied from the control substrate and the pressure detection signal sent to the control substrate. |
