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 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. You will find a complete overview of the available materials and seals in the "Configurator" at www.vega.com and "Products". Application area Housing versions The VEGAPULS 31 is the ideal radar sensor for non-contact level measurement in standard applications on all industrial plants. The housing is made of PBT plastic and is available in protection rating IP66/IP67. It is particularly suitable for level measurement and measured value visualisation 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. Electronics versions The instrument is available in the 4 … 20 mA/HART electronics version. Your benefit • Maintenance-free operation due to non-contact 80 GHz radar technology • Exact measurement results independent of medium properties and process conditions • Local display for easy checking of the level. 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
