Specification sheet Two-wire 4 … 20 mA/HART Radar sensor for continuous level measurement Technical data Measuring range Deviation Beam angle Output signal Process fitting Mounting connection Process pressure Process temperature Ambient temperature Operating voltage Materials The wetted parts of the instrument are made of PVDF. The process seal is made of FKM. The connection cable is PUR insulated. You will find a complete overview of the available materials and seals in the "Configurator" at www.vega.com and "Products". Application area The VEGAPULS C 21 is the ideal radar sensor 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, in 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. Your benefit Housing versions The housing is optimized for applications in the water/waste water industry and manufactured of PVDF. Due to the encapsulated cable gland, protection rating IP66/IP68 (3 bar) is achieved. Electronics versions The instruments are available in different electronics versions. Apart from the two-wire electronics with 4 … 20 mA/HART, two digital versions with SDI-12 and Modbus/Levelmaster protocol are possible. • Maintenance-free operation due to non-contact 80 GHz radar technology • Exact measuring results independent of product, process and ambient conditions • High plant availability because wear and maintenance-free. Exact measurement results independent of medium, process and ambient conditions Function The sensor emits a continuous radar signal through the antenna. The emitted signal is reflected by the medium and received as an echo by the antenna. 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. VEGA Grieshaber KG, Am Hohenstei
