VEGAPULS Air 41 • Autarkic device with measured value transmission via radio technology
64808-EN-210426
After activation, a single measurement is carried out and the cyclic
measurement interval is started. The measured value is sent once
via LoRaWAN or mobile radio. The sensor delivers the distance value
from the sealing surface of the thread or flange lower side to the
product surface. The conversion into level is carried out, for example,
in the VEGA Inventory System on the application server or in a cloud
service.
In the activated state, the device is woken up via the integrated clock
and carries out a measurement cycle (measurement and transmis-
sion). The measurement and transmission interval runs on the basis
of the factory preconfiguration or a configuration set by the user. After-
wards, the device automatically enters the energy-saving sleep state.
Note:
In sleep mode, it is not possible to connect to the device via
Bluetooth.
7.4 Single measurement
The device offers the possibility to test the communication in the
respective network. The current measured value is determined and
transmitted once outside the cyclic transmission. In addition, a LoRa
Join and a single location determination is carried out.
The procedure is done by new activation via NFC or magnet as
described above. The sensor is simultaneously activated for the cycli-
cal transmission of measured values. The transmission cycle of an
already activated sensor is not changed by this.
7.5 Localization
The LTE-M/NB-IoT version of the device has the function " Loca-
tion determination ". This is carried out via an integrated GNSS/GPS
receiver via navigation satellites. The function " Location determina-
tion " can be switched on or off via the VEGA Tools app or PACTware/
DTM.
1)
Tilting or raising the device triggers a single location determination. A
position of 20° to the vertical must be passed through. Furthermore,
entering a new mobile radio cell triggers a single location determina-
tion. In both cases, location determination is not started until the next
cyclic measured value determination. If no satellite signal is found
within 180 s and therefore no position is determined, the process is
aborted.
Note:
In LoRa mode or with the LoRa version of the device, there is gener-
ally no location determination.
