Specification sheet 4 … 20 mA/HART - two-wire Radar sensor for continuous level measurement of liquids Technical data Measuring range up to Process fitting Thread from G1½; 1½ NPT; flanges from DN 40, 1½" Process pressure Process temperature Ambient, storage and transport temperature Operating voltage SIL qualification Materials Application area The VEGAPULS 65 is a radar sensor for continuous measurement of liquids under simple process conditions. It is particularly suitable for level measurement in vessels with small process fittings and under simple process conditions. The slim rod antenna enables the installation in small vessel openings. Your benefit • Maintenance-free operation thanks to non-contact measuring principle • High plant availability, because wear and maintenance free • Exact measuring results independent of process conditions Function Extremely short microwave pulses are emitted by the antenna system in the direction of the measured product, reflected by the product surface and received back again by the antenna system. The time from emission to reception of the signals is proportional to the level in the vessel. A special time stretching procedure allows reliable and precise measurement of the extremely short signal running times. The wetted parts of the instrument are made of PVDF, 316L or PTFE. The process seal is made of FKM. You will find a complete overview of the available materials and seals in the "Configurator" at www.vega.com and "VEGA Tools". Housing versions The housings are available as single chamber or double chamber version in plastic, stainless steel or aluminium. They are available with protection ratings up to IP 68 (1 bar). Electronics versions The instruments are available in different electronics versions. Apart from 4 … 20 mA/HART in two and four-wire version, there are also digital versions with Profibus PA, Foundation Fieldbus and Modbus protocols. Another HART version is available with integrated accumulator. Supplementary electronics For instruments with double chamber housing two supplementary electronics such as radio module or a power pack are available. Approvals The instruments are suitable for use in hazardous areas and are approved e.g. according to ATEX and IEC. The instruments also have various ship approvals such as e.g. GL, LRS or ABS.
