7. 2 Mode of operation and system structure 2 1 Measuring principle REFLEX TDR TDR Time Domain Reflectometry The converter electronics sends an electromagnetic pulse to the probe system That electromagnetic pulse travels at the speed of light down to the product surface Here the pulse gets partially reflected and travels back to the converter electronics The distance between the converter flange and product surface is therefore directly proportional to time For a distance of 1m the pulse s travel time is 6 7ns 6 7 10 seconds They are defined by two plausibility Windows one for the emitted pulse and one for the reflection radar The polarity and the amplitude of the partially pulse reflected REFLEX pulse depends on the epsilon r of the two mediums which are above and below the reflecting surface Under normal circumstances the medium above the surface is a gas with an e close to 1 0 and the medium below is the process medium with an higher The figure on the right shows a typical pulse reflection of such a standard application The advantage of the TDR measuring principle is that the travel time of the pulse and therefore the accuracy of the level measurement is completely independent of the and the density of the process medium One of the front end electronics main tasks is to sample the complete measurement signal at the upper probe end As the signal is too fast to get sample
