Description

Wherever centralised, web-based remote monitoring of measuring instrument data is required, the IIoT-capable WIKA radio unit model NETRIS ® 2 finds it application.

The Ex radio unit receives the data via the two intrinsically safe, analogue 4 ... 20 mA input signals. The fully encapsulated instrument with IP55 ingress protection transmits the received data continuously to a cloud via configurable data packets with LoRaWAN ® (Long Range Wide Area Network).

Battery-operated wireless transmission via LoRaWAN ® is based on LPWAN technology to enable high transmission ranges and long battery life.
