    Overview

    Radar level sensor provides non-contact measurement for a wide range of liquids, offering a measuring range of 0-20m with optional 4–20mA, HART, or RS485 outputs. This radar type level transmitter features a robust design with an LCD display and flange installation options such as DN80, DN100, and DN150. With IP67 protection, it is suitable for corrosive, volatile, or vapor-filled environments.

    Feature

    • 10° narrow beam design: The radar level sensor concentrates energy within a narrow beam, delivering powerful medium penetration and improved echo stability.
    • Wide application range: Features a waterproof, dustproof, and corrosion-resistant design for reliable use in harsh industrial environments.
    • 304 stainless steel housing: Durable, wear-resistant, and shockproof construction ensures long-term stability and extended service life.

    FAQ
    ❯

    Radar level sensors can measure water, oil, acid and alkali solutions, slurries, and some solid powders. Different models are designed for liquids or solids; the appropriate model must be selected based on the characteristics of the medium.

    ❯

    Yes, some models can withstand temperatures up to +250℃ or even higher. High-temperature sensors should be selected, along with suitable process connections and sealing materials.

    ❯

    Yes, when used with acid, alkali, or salt solutions, PTFE (polytetrafluoroethylene) or PVDF antenna materials should be selected. The housing should also be made of corrosion-resistant stainless steel or plastic.
