Brief: Let’s dive in — see this solution in action and notice the key moments. This video provides a detailed walkthrough of the HQ-51L Parabolic Radar Level Gauge, showcasing its installation on container tops and demonstrating how its narrow beam and high directionality enable accurate measurement in challenging environments with high dust, temperature, and interference.
Related Product Features:
  • Features a 26GHz frequency and a 40m measurement range for large-scale industrial applications.
  • Provides high directionality with a 5° beam angle, minimizing interference from tank walls and obstacles.
  • Offers precise measurement with ±10mm accuracy and 1mm resolution for reliable level monitoring.
  • Suitable for high-temperature environments with a process temperature range from -40℃ to 85℃.
  • Supports multiple output signals including 4-20mA, HART, RS485, and Foundation Fieldbus for flexible integration.
  • Designed with explosion-proof certification Ex db IIC T6 Gb for use in hazardous areas.
  • Constructed with durable SS304L/SS316L antenna materials for corrosion resistance and longevity.
  • Ideal for measuring liquids, solids, particles, and dust in cement, power, and steel industries.
FAQs:
  • What is the main advantage of the parabolic antenna design?
    The parabolic antenna design provides high directionality, converging microwaves into a narrow beam. This allows it to measure accurately even with many interferences inside the tank, such as stairs, without being affected by false echoes.
  • In which industries and applications is this radar level gauge suitable?
    It is suitable for measuring large range, high dust, high temperature, and low dielectric constant media in industries like cement, power, and steel. It is designed for non-contact liquid and material level measurement installed on container tops.
  • What are the key technical specifications for measurement performance?
    Key specifications include a 40m measure distance, ±10mm precision, 1mm resolution, a 5° beam angle, and a blind area of 0.6m. It operates at 26GHz and supports various output signals and power supplies.
  • What explosion-proof rating does the HQ-51L have?
    The HQ-51L has an explosion-proof grade of Ex db IIC T6 Gb, making it safe for use in hazardous environments where explosive gases or dust may be present.
