Radar Level Measurement
LEVEL
The radar level measuring device consists of a housing containing the electronics, a process connection with an antenna and a sensor. The radar sensor transmits brief radar pulses with a duration of approximately 1 ns from the antenna. These pulses are reflected by the filling material and received by the antenna as echoes. Radar waves are propagated at the speed of light. The delay time of the radar pulses from transmission to reception is proportional to the distance and therefore to the filling level. The filling level determined in this way is converted into a corresponding output signal and issued as a measured value. The filling level sensors are frequently used for aggressive media as well as dynamic process conditions, such as high temperatures or pressure fluctuations. As with the ultrasonic measurement, the measurements in this case are performed without contact. Since no direct contact with the medium is required, the measuring principle is ideal for hygienic applications.
