ABSTRACT:
A method for determining a distance between a radar sensor and a reflection surface of a material comprising the following steps. The radar sensor is energized via a two-wire control loop which allows for data communication and an internal energy store. An echo profile is generated and analyzed to calculate the distance. During generation of the echo profile, the generation process is interrupted at least once to recharge the energy store via the two-wire control loop.
