AI Technical Summary
The existing lens antenna material PTFE has poor mechanical stability and wear resistance in high temperature and corrosive environments, resulting in a limited service life of radar level gauges.
The lens antenna is made of PEEK material, combined with waterproof rubber rings and O-rings to improve sealing. It is designed as a hollow planar structure to prevent water vapor from condensing. The bottom of the lens antenna is designed with an arc shape to enhance corrosion resistance.
PEEK lens antennas are superior to PTFE in terms of mechanical properties, temperature resistance, and chemical stability. They have a tensile strength of 90-200 MPa and a heat resistance temperature of up to 250 degrees Celsius, which significantly improves the service life and corrosion resistance of radar level gauges.
