Radar level sensor VA42

The radar level sensor VA42 is a stand-alone radar sensor with radio transmission of measured values. The device transmits a radar signal via its antenna. The emitted signal is reflected by the medium and received by the antenna as an echo. The level determined from this is converted into a corresponding output signal and transmitted wirelessly.

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 network or a LoRaWAN network on the system side. The data is forwarded or analysed via an asset management system, e.g. VEGA Inventory System.

The wetted parts of the device are made of PVDF.

The sensor housing with a high degree of protection IP66/IP68 (0.2 bar) enables maintenance-free continuous operation outdoors.
