5. Performance specifications 5.1. Measurement deviation diagram Measuring deviation [mm] Reference plane Antenna edge Recommended measuring range Measuring range 6. Product operation 6.1. Measuring principle The radar measuring device consists of an electronic housing, a process connection element with antenna and a sensor. The antenna emits short radar pulses with a duration of approximate 1 ns to the medium. These pulses are reflected by the medium surface and received by the antenna as echoes. Radar waves travel at the speed of light. The running time of the radar pulses from emission...
