Radar level sensor VA41

Type VA41

Autarkic sensor with measured value transmission by radio technology


Application Area

NB-IoT/CAT-M1, LoRa, measuring range up to 15m, accuracy +/-2mm

Radar level sensor VA41 is the ideal sensor for all autarkic applications with bulk solids and liquids. It is particularly suitable for level measurement in mobile bulk solids silos for dry mortar, concrete and plasters as well as in liquid tanks of all kinds. VEGAPULS Air 41 offers an economical solution through simple and reliable mounting without additional power supply.
