Measuring principles The ultrashort microwave impulse with very short emission energy can be emitted and received through antenna. The radar wave moves at the velocity of light. The moving time can be converted into substance position signal through electrical components. A special time-extension method can secure stable and precise measurement within very short time. Even under very complicated working conditions, such as the existence of false wave echo, it is possible to precisely analyze the wave echo of the substance position by using the latest micro-processing technology and debugging software.... Input The antenna receives the reflected microwave impulse and transmits it to the electric circuit, the micro processor processes this signal, recognizes the wave echo produced by microwave impulse on the substance surface. The correct microwave echo signal recognition is completed intelligent software, the precision can reach millimeter grade. The distance from the substance surface D is proportional to impulse time stroke T: D=C × T/2 Among them, C is velocity of light As the distance of empty tank E is known, the substance position L is: L=E-D Output By inputting empty tank height E (=O), full tank height F (=full) and some application parameter to set up, the application parameter will make the gauge adapted to the measuring environment, corresponding to 4-20mA output.. Applied mediums: ·XKTRD80 series of radar substance position gauge is suitable for the non-contact continuous measurement of liquids, slurry and granule materials, it is suitable for occasions of great temperature and pressure changes, inert gases and gas volatilizations. ·The method of microwave impulse measurement secures normal operation within the range of industrial frequency wave bands. The wave beam energy is relatively low, so it is no harm to human and environment and can be installed inside of all kinds of metal, non-metal containers or pipes.
