A packaging technology for MECS components, which allows the realization of extremely robust components which are resistant to high temperatures and media. Such a component includes at least one micro-electrochemical sensor (MECS) component having a diaphragm, which is developed in a layer construction on the substrate of the component and spans an opening in the substrate rear side, and a carrier for the mounting and electrical contacting of the MECS component on an application circuit board. The MECS component is bonded to the carrier in flip chip technology, so that a hermetically tight mechanical connection between the top surface of the MECS component and the carrier surface exists at least in one connection region, and an electric connection between the MECS component and the carrier exists in at least one contact area.

A sensor device for sensing at least a proportion of at least one gas component of a gas in a measurement gas space, in particular for detecting oxygen in an exhaust gas of a combustion machine, is proposed. The sensor device includes at least one sensor element. The sensor element includes at least one first electrode and at least one first reference electrode and at least one second reference electrode. The second reference electrode is connected to at least one reference gas channel. The first electrode is connected to the first reference electrode and the second reference electrode by at least one respective solid electrolyte. The sensor element has at least one diffusion element between the first reference electrode and the reference gas channel.

A sensor element for determining concentration of at least one constituent of a gas mixture operates on an electro-chemical measuring process and includes a gas measuring chamber; a pair of electrodes and an electrode chamber located between the pair of electrodes; and a diffusion conduit adjoining the electrode chamber and having a gas input which connects with the gas measuring chamber, having a gas output which connects with the electrode chamber, and having at least one cross-sectional area including a height, w, and a length, L, which height, w, has a preselected minimum value, and which length, L, has a value which is equal to or greater than the preselected minimum value of the height, w. The constituent of the gas mixture has a mean free path length through the sensor element, the gas measuring chamber has a cross-sectional area including a height and a length each of which are at least as large as the minimum height, w, of the diffusion conduit, and the height, w, of respective ones of the at least one cross-sectional area of the diffusion conduit is at least a multiple of the mean free path length of the constituent of the gas mixture to be measured. Advantageously, substantially only gaseous phase diffusion occurs when the predetermined minimum value of the height, w, is at least a multiple of a minimum value of the mean free path length for the gas constituent measured.

Planar polarographic sensor for determining the lambda value of gas

The invention is based on a planar sensor element for determining the oxygen content of gas mixtures, particularly in internal combustion engines such as those found in automobiles. The sensor element comprises a measuring cell and an integrated heat conductor embedded in electric insulation all of which rest on a solid electrolyte substrate. At least one hollow chamber separates one or several parts of the insulation from the solid electrolyte substrate in order to effect an improved decoupling of the sensor's heat conductor from its measuring cell.

A method to adjust the angular position of a camshaft, which is related to the arc of a crankshaft rotation, to a setpoint angular position with the help of a final controlling element that is triggered by an actuating signal from a controlling device that becomes operational when a control program is run. The final controlling element is able to be triggered in each case by one of three values of the actuating signal; the re-adjustment rate (v.sub.-- ESTIMATED) of the camshaft is estimated for its level at the beginning of the subsequent program run; from this re-adjustment rate and the known time response (c, v.sub.-- END) of the camshaft re-adjustment, after the switch is made to the actuating signal from the hold value, a special adjustment angle (.alpha..sub.-- ESTIMATED+) is estimated; and the change is already made from the early or late value of the actuating signal to its hold value when the deviation between the adjustment angle (.alpha..sub.-- ESTIMATED+) and the setpoint angular position lies within a tolerance band. The angular position of the camshaft is thereby able to be adjusted in a rapid and stable manner.
