Specification sheet Autarkic radar sensor with measured value transmission via radio technology Continuous level measurement for bulk solids and liquids Technical data Measuring range Deviation Process fitting Process pressure Process temperature Ambient, storage and transport temperature Radio technology Application area VEGAPULS Air 41 is the ideal sensor for all stand-alone applications with bulk solids and liquids. It is particularly suitable for level measurement in mobile bulk solids silos holding dry mortar, concrete or plaster, as well as in liquid tanks of all kinds. VEGAPULS Air 41 represents an attractive, low-cost solution as it is easy to install and put into operation and requires no additional power supply. Protection rating up to 15 m (49.21 ft) ≤ 2 mm Thread G1½, 1½ NPT, R1½ -1 … 2 bar (-100 … 200 kPa/14.5 … 29.00 psig) -20 … +60 °C (-4 … +140 °F) -20 … +60 °C (-4 … +140 °F) NB-IoT (LTE-Cat-NB1), LTE-M (LTE-CATM1), LoRa WAN IP66/IP68 (0.2 bar) according to IEC 60529, type 6x according to NEMA Materials The wetted parts of the instrument are made of PVDF. Housing version Your benefit The sensor housing with high protection rating IP66/IP68 (0.2 bar) enables maintenance-free continuous operation outdoors. • Easy installation thanks to autarkic power supply and radio technology Application examples • Exact measuring results independent of product, process and ambient conditions • Maintenance-free operation due to non-contact 80 GHz radar technology Function The sensor emits a radar signal through the antenna. The emitted signal is reflected by the medium and received as an echo by the antenna. The resulting level is converted into a respective output signal and wirelessly transmitted. Measured value transmission Depending on the availability of the radio networks, the device transmits its measured values wirelessly to an LTE-M (LTE-CAT-M1) or NB-IoT (LTE-CAT-NB1) mobile radio or a plant-side LoRaWAN network. The transmission or evaluation is carried out via an Asset Management System, e.g. VEGA Inventory System.
