| 摘要 |
A sensing apparatus for sensing at least two physical quantities is disclosed. The sensing apparatus includes a first transducer (62, 122, 212) that provides a first output signal proportional to a first measured quantity and a second transducer (64, 155, 214) that provides a second output signal proportional to a second measured quantity. An excitation regulator device (82, 140, 162) is connected to the first transducer (62, 122, 212) and the second transducer (64, 155, 214). The excitation regulator device (82, 140, 162) provides an excitation signal to the second transducer (64, 155, 214) so that the second transducer output signal is referenced to the first transducer output signal in order to obtain a resultant output signal which is a combination of the first and second output signals. |
