Abstract

Uppfinningen avser en trycksenor (10A, 10B) för ett personskyddssystem hos ett fordon, innefattande ett sensorhus (20) och basplatta (12) anordnad inne i sensorhuset (20, på vilken en mätenhet (14) är anordnad och som innefattar ett trycksensorelement och en sensorkrets, liksom även en motsvarande trycksensoranordning (1) för ett personskyddssystem hos ett fordon innefattande minst en sådan trycksensor (10, 10A). Här bildar sensorhuset (20) vid en första ände en stickkontakt (20A) och vid en andra ände ett mätrum (28) i vilket ett tryck som skall mätas råder, varvid basplattan (12) avskiljer stickkontakten (20A) fluidmässigt från mätrummet (28), varvid trycksensorelementet och sensorkretsen är anordnade i ett gemensamt hus och trycksensorelementet är via en tryckinloppskanal fluidmässigt förbundet med mätrummet (28).The invention relates to a pressure sensors (10A, 10B) for a personal protection system of a vehicle, comprising a sensor housing (20) and base plate (12) arranged inside the sensor housing (20, on which a measuring unit (14) is arranged and which comprises a pressure sensor element and a sensor circuit, as well as a corresponding pressure sensor device (1) for a personal protection system of a vehicle comprising at least one such pressure sensor (10, 10A). 28) in which a pressure to be measured prevails, the base plate (12) separating the plug contact (20A) fluidly from the measuring space (28), the pressure sensor element and the sensor circuit being arranged in a common housing and the pressure sensor element being fluidly connected to the measuring space (28) via a pressure inlet channel. ).
