    摘要： A method for operating a sensor module having a humidity sensor for ascertaining the relative humidity, at least one first measured value for the relative humidity being ascertained with the aid of the humidity sensor. It is provided that an ambient temperature in the area of the humidity sensor is changed with the aid of a temperature control device; at least one second measured value for the relative humidity is ascertained with the aid of the humidity sensor after the change in ambient temperature in the area of the humidity sensor; and an operating state and/or a proper operation of the humidity sensor is inferred as a function of the first and second measured values.

    摘要： A sheathed-element glow plug to be mounted in a combustion chamber is proposed, a rod-shaped heating element being situated in a concentric bore hole of the housing. The heating element has a first current-carrying layer, a second current-carrying layer, and an insulating layer, the insulating layer separating the first current-carrying layer and the second current-carrying layer. The first current-carrying layer and the second current-carrying layer being connected at the end of the heating element on the combustion chamber side by a conducting-layer crosspiece. The first current-carrying layer and the second current-carrying layer are different lengths, the cross section of the first current-carrying layer in a first section at the end of the heating element away from the combustion chamber being greater than the cross section of its remaining length, and the second current-carrying layer not extending into the first section.

    摘要： A method for producing ceramic composite bodies, in particular, cylindrical ceramic bodies for sheathed-element glow plugs, in which a plurality of shaping sleeves, which accommodate piece parts premolded by cold pressing, are inserted into corresponding bore holes of a vertically standing supporting plate that is heated via additional bore holes with the aid of cartridge heaters or a heat transfer liquid. The vertically standing supporting plate with the shaping sleeves is then clamped between two press plates of a press, and the piece parts located inside are subsequently pressed by press pins which, on both sides, pass through the press plates and into the shaping sleeves. Upon completion of the necessary pressure keeping period, the pressed compound, after retraction of the press pins and opening the press, can be hardened in a non-pressurized manner in the shaping sleeves located in the withdrawn supporting plate that is subjected to further heating. Finally, the pressed material can be removed from the shaping sleeves after the same have been cooled by air, and can be ground into the final shape using a grinding machine.

    摘要： A method and a device for detecting the exchange of sheathed-element glow plugs (GPE) in a combustion engine, in which at least one electric characteristic quantity of at least one glow plug is measured at the beginning of a driving cycle, an instantaneous value of this characteristic quantity is determined and compared to at least one stored value of the same electric variable quantity of this glow plug, which was determined at the beginning of at least one preceding driving cycle, and if the deviation of the instantaneous value from the stored value exceeds a specifiable threshold value, an exchange of the glow plug (GPE) will be inferred.

    摘要： A ceramic sheathed-element glow plug is proposed in which a metallic tubular holder holds a ceramic U-shaped heating device in a cantilevered fashion at its combustion chamber side end and has a terminal stud for applying a voltage to the ceramic heating device on the end remote from the combustion chamber. At its end enclosed by the holder, the ceramic heating device has a segment of greatest diameter and is coated with an insulating layer which has recesses for an electrical contacting. One recess is provided at the end of the ceramic heating device remote from the combustion chamber and a second recess is provided on the external wall of the ceramic heating device. A for an electrically conductive sealing compound is provided between the external wall of the ceramic heating device and the internal wall of the holder.
