Specification sheet Two-wire 4 … 20 mA/HART Radar sensor for continuous level measurement Technical data Measuring range up to Deviation Beam angle Measuring frequency Output signal Process fitting Mounting connection Process pressure Process temperature Ambient temperature Bluetooth standard Effective range typ. Operating voltage Protection rating 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 • Maintenance-free operation due to non-contact 80 GHz radar technology • Exact measurement results independent of medium properties and process conditions • High accuracy and universal measuring range. Maintenance-free operation due to non-contact measuring principle 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 Hohenstein 113, 77761 Schiltach/Germany, www.vega.com Materials The wetted parts of the instrument are made of PVDF. The process seal is made of FKM. The connection cable is PUR insulated. A complete overview of the available materials and seals can be found on our homepage under " Products" and " Configure & Order". 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. Approvals Worldwide approvals are available for VEGA instruments, e.g. for use in hazardous areas, on ships or in hygienic applications. The technical data in the respective safety instructions are valid for approved instruments (e.g. with Ex approval). In some cases, these data can differ from the data listed herein.
