2.2 Description
®
The NETRIS
3 transmits data over long distances by means of innovative LPWAN
technology ("Low-Power Wide-Area Network"). It is therefore possible to carry out
installations inside buildings, in cellars or in underground tanks without any problems.
The transmission of the measured values to the IIoT platform is carried out at a preset
sending interval. The measurement and sending intervals, and also the alarm limits,
for particular measured values can be configured over the LoRaWAN
configuration can be carried out via the cloud.
2.3 Functional principle
The measuring signal is transmitted digitally from the WIKA measuring instrument via a
cable to the NETRIS
®
The NETRIS
3 uses the LoRaWAN
energy-saving operation.
This means that communication with a suitable gateway mainly consists of uplinks
(messages originating from the measuring instrument). An uplink always occurs in regular,
preset cycles (transmission rate). The measuring rate can be defined independently of the
WIKA operating instructions, model NETRIS
