The Milesight EM410-RDL Distance Level Sensor is a high-performance, non-contact sensor designed for precision distance and liquid level monitoring. Using advanced millimetre-wave (mmWave) radar technology, it delivers consistent, stable readings over long ranges, even in the most challenging conditions.
The Milesight EM410-RDL is a high-performance, non-contact sensor utilising advanced 60GHz Millimetre Wave (mmWave) radar technology for precision distance and liquid level monitoring. With a highly focused 8° narrow beam angle, this advanced radar can penetrate non-conductive materials such as plastics and plants. This ensures uninterrupted, highly accurate measurements without requiring a direct line of sight, making it entirely unaffected by environmental factors like dust, steam, or overgrowth.
Ideal for a wide range of applications, including:
Built to withstand explosive atmospheres, the EM411-RDL integrates ATEX Zone 0 certification with a chemical-resistant PVDF housing and robust IP68 rating. This durable design ensures accurate monitoring and maintenance-free operation even in harsh conditions, effectively eliminating ignition risks and comprehensively safeguarding personnel and critical assets.
An ATEX version is available for the EM411-RDL only; contact us at contact@alliot.co.uk for more details.
