47. MCW radar transmits a continuous wave The frequency of the wave is constantly increasing this is known as the sweep By the time the first part of the wave has been reflected off the target and returned to the device the part of the wave that is just being emitted is at a higher frequency The difference in frequency between the transmitted and received signals is proportional to time of flight Electromagnetic wave propagation is virtually unaffected by temperature or pressure changes or by changes in the vapor or dust levels inside a vessel SITRANS LR 460 consists of an enclosed electronic component coupled to an antenna and process connection The electronic component generates an electromagnetic signal from 24 2 GHz to 25 2 GHz that is directed to the antenna The signal is emitted from the antenna and the reflected echoes are digitally converted to an echo profile The profile is analyzed to determine the distance from the material surface to the reference point on the instrument This distance is used as a basis for the display of material level and output Measurement Response The measurement response response rate limits the maximum rate at which the display and output respond to changes in the measurement Once the real process fill empty rate m s is established a response rate can be selected that is slightly higher than the application rate The response rate automatically adjusts the filters that affect the output respon
