DIMENSIONS
Simple possible applications
Safe monitoring in hazardous environments
The EM411-RDL is designed to withstand explosive atmospheres and combines ATEX Zone 0 certification with a chemically resistant PVDF housing and a robust IP68 rating. This durable design ensures accurate monitoring and maintenance-free operation, even under aggressive conditions, effectively eliminating ignition risks and fully protecting personnel and critical assets.
*ATEX certification is only available for the model EM411-RDL.
Radar technology for customised applications
In addition to the large measurement range, radar technology can also measure through objects, including plastics and plants, and is less sensitive to snow, dirt, dust, steam, and the like, making it suitable for a wider range of applications.
Standard applications: Manholes, Sewer monitoring, .....
Application scenario mode
Choice of modes ‘standard’, ‘rainwater pit’, ‘sewer pit’ and ‘storage tank’ for easy scenario settings.
Built-in tilt sensor
Enables level measurement under a tilted angle and sends timely alerts when the device has been accidentally moved.
Flexible thread options
Thanks to the choice of both NPT and G thread options, the device guarantees seamless compatibility in all global markets, including North America.
Monitoring of rainwater wells Monitoring sewer level
Monitoring Silos
