SENSOR UNIT WITH AN ELECTRIC CONNECTION OF THE SENSOR HOUSING FOR DISCHARGING AN ELECTROSTATIC CHARGE OF A MOTOR VEHICLE

摘要

The invention relates to a sensor unit (2) for installing into a motor vehicle or trailer. The sensor unit has a sensor measuring structure (16) for sensing at least one physical variable, a sensor housing (12) which partly or completely surrounds the sensor measuring structure (16), and at least two connection lines (18). The sensor housing (12) of the sensor unit (2) is galvanically connected to a conductive part of the motor vehicle or trailer, and the sensor measuring structure (16) can be connected to an analyzing device (6) via the connection lines (18). In order to discharge a present electrostatic charge from the conductive part of the motor vehicle or trailer, the sensor unit (2) has a specified discharge path (4) between the electrically conductive sensor housing (12) and a connection line (18) or between the sensor housing (12) and the sensor measuring structure (16) such that the electrostatic charge is discharged via the analyzing device (6) connected to the sensor unit (2). The invention further relates to a sensing and analyzing device comprising a sensor unit (2) according to the invention and an analyzing device (6), to a motor vehicle or trailer comprising at least one sensor unit (2) according to the invention and/or at least one sensing and analyzing device according to the invention, and to a method for protecting the analyzing device (6).
