WIKA NETRIS 3 LoRaWAN Radio Unit for Hazardous Area Monitoring

When you work in a plant that handles gas or dust, a loss of sensor data can mean a safety breach, costly downtime, or even an accident. Operators need a way to collect measurements from hazardous zones without running long cables or exposing electronics to explosions. The WIKA NETRIS 3 LoRaWAN Radio Unit for Hazardous Area Monitoring gives you a wireless link that works inside ATEX-rated areas, sending data reliably over many kilometres. It removes the need for expensive wiring while keeping your monitoring system safe and compliant.

WIKA NETRIS 3 LoRaWAN Radio Unit for Hazardous Area Monitoring with WIKA

Imagine a sensor that can talk to your control room from a dangerous zone without any wires. That is what this radio unit does. It uses LoRa technology to carry temperature, pressure or gas-concentration data up to ten kilometres away. If you have missed readings because a cable failed, you will feel the relief of continuous, secure data flow. WIKAs wireless bridge proven expertise ensures the device meets the strict ATEX, IECEx and CSA standards for explosive atmospheres.

Usages

The radio unit can be attached directly to a pressure transmitter in a refinery, mounted on a wall near a dust collector, or linked to a temperature probe in a chemical storage tank. It works in oil-and-gas fields, mining shafts, wastewater treatment plants and any place where hazardous gases or fine dust are present. Because it runs on a long-life lithium thionyl chloride battery, you can install it in remote spots and forget about maintenance for years.
