Abstract: A sensor for determining the level and temperature of a liquid, in particular in a motor vehicle, has an elongate housing (1), in which all the components required for temperature measurement and level measurement are accommodated. This housing (1) consists of two half shells (2, 3) which rest one on the other and of which one half shell (3) has all the components required for level measurement and the wiring and resistance wire (21) necessary for this purpose and the other half shell (2) has all the components required for temperature measurement and the wiring necessary for this purpose.

Abstract: A sensor for determining the level and/or temperature of a liquid, in particular in a motor vehicle, has an elongate housing (1), in which all the components required for temperature measurement and level measurement are accommodated. This housing (1) consists of two half shells (2, 3) which rest one on the other and of which one half shell (3) has all the components required for level measurement and the wiring and resistance wire (21) necessary for this purpose and the other half shell (2) has all the components required for temperature measurement and the wiring necessary for this purpose.

Abstract: In the case of a pressure sensor (1) a measuring cell (4) is fixed together with a retaining body (9) in a housing (2) of the pressure sensor. For this purpose, the housing (2) has a constriction (15) encircling it on the outside. A contact base (11), which is placed at the top onto the retaining body (9), is fixed by means of an inwardly bent section (18) of the housing (2), with the result that the pressure sensor (1) is closed in a sealed manner. The fixing of the retaining body (9) by means of the constriction (15) means that the pressure sensor (1) is also suitable for particularly high pressures with the risk that the retaining body (9) could slip in the housing (2) due to the pressure acting on the measuring cell (4) being excluded.

Abstract: A pressure sensor has a movable diaphragm stretched directly between the annular pressing surfaces of two housing parts, and an electrical measuring device. In an area that is located radially outward as viewed from the pressing surfaces, the diaphragm has a sealing ring that abuts both housing parts. As a result, transverse vibrations of the diaphragm are reliably supported.

Abstract: A sensor chamber (7) is provided in a holder (5) of a tank insert (4), a pressure sensor (8) being inserted into said chamber. This pressure sensor (8) rests on a circumferential packing (9) of a shoulder (10) of the sensor chamber (7).
