Description
The model NETRIS ® 3 IIoT-capable radio unit is used wherever centralised, web-based remote monitoring of measuring instrument data is required.
The Ex radio unit already receives the data digitally from a WIKA measuring instrument via the intrinsically safe interface. The fully encapsulated instrument with IP65 ingress protection transmits the received data continuously to a cloud via configurable data packets with LoRaWAN ® .
Battery-operated wireless transmission via LoRa ® ('long range') is based on LPWAN technology ('low-power wide-area network') to enable high transmission ranges and long battery life.
The radio unit is connected to a suitable WIKA measuring

Special features
- IIoT-capable with LoRaWAN ® transmission
- Battery-operated LoRa ® radio transmission based on LPWAN technology
- High transmission range for the measured values (up to 10 km) with long battery life (up to 10 years)
- Exchange of the radio unit possible in ATEX zones
