The VEGA VEGAPULS C 21 wired radar sensor is ideal for non-contact level measurement with high accuracy requirements in all standard applications where a high degree of protection is required. It is particularly suitable for level measurement in water treatment, pumping stations, and rain overflow basins, for flow measurement in open channels, for level monitoring, and for many other industrial areas. The sensor is suitable both for measuring liquids and for use on small bulk solids silos or bulk solids containers.

The VEGAPULS C 21 sensor 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 connection cable is PUR insulated. The housing is optimized for applications in the water/wastewater industry and manufactured of PVDF. Due to the encapsulated cable gland, protection rating IP66/IP68 (3 bar) is achieved. The instruments are available in different electronics versions. Apart from the two-wire electronics with 4 to 20mA/HART, two digital versions with SDI-12 and Modbus/Levelmaster protocol are available.
