<p>A measuring apparatus for outputting a measurement signal representing the difference between a first pressure and a second pressure. The apparatus includes a first pressure measuring transducer module for outputting a sequence of first signals representing the first pressure; a second pressure measuring transducer module for producing a sequence of second signals representing the second pressure; an evaluation module for ascertaining a sequence of difference values between the two pressure values and for outputting a sequence of fourth signals, which, in each case, represent the pressure difference; a first cable connection between the first and second pressure measuring transducer module; and a second cable connection between the second pressure measuring transducer module and the evaluation module. The modules are separated spatially from one another. The second pressure measuring transducer module has a mapping unit, which is provided for receiving the sequences of first and second signals, and for outputting to the evaluation module via the second cable connection a sequence of third signals, which, in each case, contain the pressure values.</p> |
