| 20120103088 | APPARATUS FOR DETERMINING AND/OR MONITORING A PROCESS VARIABLE - An apparatus for determining and/or monitoring at least one process variable of a medium. The apparatus includes: at least one mechanically oscillatable unit, which comes in contact at least partially with the medium; at least one transducer unit, which excites the mechanically oscillatable unit to execute mechanical oscillations and which receives mechanical oscillations from the mechanically oscillatable unit; and at least one housing. At least one limiting element is provided. The limiting element is embodied and arranged in such a manner that the limiting element at least partially surrounds the mechanically oscillatable unit and the therefrom resulting reduction of volume surrounding the mechanically oscillatable unit increases the measuring sensitivity of the apparatus. Furthermore, the invention relates to a limiting element. | 05-03-2012 |
| 20110265573 | APPARATUS FOR DETERMINING AND/OR MONITORING ( ) PRESSURE - An apparatus for determining and/or monitoring pressure. The apparatus comprises at least one pressure transducer, which transduces pressure into an electrical signal. The invention includes the features that at least one acoustic sensor is provided, that the acoustic sensor registers acoustic signals and transduces such into electrical signals, and that the acoustic sensor is mechanically and/or acoustically coupled with the pressure transducer. | 11-03-2011 |
