Overview
EM411-RDL overview
Overview
The EM411-RDL extends the EM41x-RDL radar platform with ATEX Zone 0 certification for intrinsically safe monitoring in explosive atmospheres. Millimetre-wave radar delivers stable level readings in aggressive chemical environments.
ATEX Zone 0 Safety
Built for hazardous locations, the EM411-RDL combines Zone 0 approval with corrosion-resistant PVDF and IP68 sealing to eliminate ignition risks while maintaining measurement accuracy.
Precision Radar Measurement
60 GHz radar with an 8° beam measures liquids and smooth solids from 0.3 to 12 m, resilient to dust, steam, condensate and surface turbulence.
Application Scenario Modes
Pre-configured modes for standard sites, rainwater wells, sewage wells and storage tanks speed deployment. Tilt monitoring alerts if the device is dislodged.
Connectivity Options
LoRaWAN backhaul integrates with Milesight gateways. Cat.1 cellular supports operator IoT platforms via TCP/UDP/MQTT/AWS.

Applications
EM411-RDL applications
Hazardous Tank Farms
ATEX Zone 0 certification enables level monitoring in explosive atmospheres without compromising safety or accuracy.
Chemical & Process Plants
PVDF housing resists aggressive chemicals while radar penetrates foam and vapor where other sensors fail.
Oil & Gas Infrastructure
Storage vessels and process tanks in classified areas gain maintenance-free, non-contact level data over wireless backhaul.
Seawater & Brine
Corrosion-resistant materials suit high-salt mist and brine environments alongside standard industrial liquids.
