Maintenance-free non-contact 80 GHz radar

A radar sensor emits high-frequency microwave pulses from its antenna towards the medium. The signal is reflected by the product surface and the transit time is measured and converted into distance and level. Because the measurement is non-contact, it is independent of density, conductivity, temperature and pressure of the medium.
