Description

The Milesight EM411-RDL is the intrinsically safe version of the EM41x series, specifically engineered for hazardous locations. Utilizing advanced 60GHz Millimeter Wave (mmWave) radar, it provides non-contact distance and level measurements with millimeter precision across a 15-meter range. Crucially, the EM411-RDL is ATEX Zone 0 certified, making it suitable for permanent installation in explosive atmospheres where flammable gases or vapors are continuously present. Its narrow beam and high-frequency radar ensure stable performance through steam, foam, and dust.

Intrinsically Safe Analytics

Zone 0 Protection Certified for the highest risk environments, ensuring safe monitoring in volatile chemical and fuel storage applications.
Narrow Field of View The 8° beam angle eliminates false echoes from tank walls or internal ladders, providing clear and accurate data.

Hazardous Area Applications

• Petrochemical & Fuel: Accurate level tracking in storage tanks for fuels, oils, and combustible chemicals.
• Wastewater & Biogas: Monitoring manholes and digesters where methane gas presence requires ATEX safety.
• Industrial Processing: Safe distance measurement in manufacturing zones with airborne dust or solvent vapors.
