Description
The VEGAPULS 21 is the ideal radar sensor for non-contact level measurement in standard applications in all industrial plants. It is particularly suitable for level measurement in water treatment, storage tanks with acids and lyes, additives in all industrial areas, or for measuring levels through a plastic tank or IBC container. The sensor is suitable both for measuring liquids and for use on small bulk solids silos or bulk solids containers.
The device emits a continuous radar signal through its antenna which is modulated in its frequency. The emitted signal is reflected by the medium and received by the antenna as an echo. The frequency difference between the emitted and received signal is proportional to the distance and depends on the filling height. The determined filling height is converted into a respective output signal and output as measured value.
The wetted parts of the instrument are made of PVDF. The process seal is made of FKM. The housing is made of PBT plastic and is available in protection rating IP66/IP67.
