AI Technical Summary
Existing radar level gauge systems face challenges in ensuring safe and efficient operation in hazardous environments by maintaining electrical isolation and preventing spark-induced ignition, particularly in areas with explosive gases or flammable products.
The system employs a dielectric antenna body made of materials like PTFE, with a conductive housing that does not fully cover the side surface, and incorporates a recess to accommodate the transceiver, ensuring a minimum separation distance of 1 mm, and uses a microwave absorbing structure to reduce unwanted side lobes, achieving intrinsic safety through conductive separation.
This configuration provides robust and cost-effective electrical isolation, meeting intrinsic safety standards by preventing spark ignition, even with potential faults, and enhancing the radar level gauge's performance and reliability in hazardous areas.
