　　range resolutionDistance resolution refers to the ability of a level radar to distinguish between two objects that are close together, rather than just one, and to measure their respective distances. If the distance interval between two objects is less than the distance resolution of the level radar, then the radar can only measure one distance value, which is not equal to the distance value of any one object, but the combination of the distance values of the two objects. The frequency modulation bandwidth of HR7380 is B=5GHz, and the minimum distance resolution is approximately 3cm, which is equal to the speed of light divided by the working bandwidth.

　　measurement accuracy：If there is only one object and it has moved a small distance, can the level radar recognize the distance change. The indicator that distinguishes the distance traveled by a single object is called accuracy. The intermediate frequency signal of HR7380 is analyzed using proprietary algorithms, with a measurement accuracy of 0.5mm.

　　blind spot(1) Refers to the measurement limit at the near end of the instrument, where the instrument cannot measure within the blind zone

　　echoThe reflected signal received by the radar.

　　Launch coneExtension of antenna beam angle.

　　False echoAny echo that is not generated by the desired target. Generally speaking, false echoes are generated by obstacles in the container.

　　multiple echo Multiple reflection echoes that appear at the target echo distance may be 2 or 3 times.

　　range(1) Refers to the farthest measurement limit of the instrument. (2) Special refers to the artificially set farthest distance beyond which the instrument does not consider data processing.

　　repetitivenessThe degree of deviation in multiple measurements of the same variable under the same conditions.

　　Threshold curveA curve that varies over time, serving as a threshold, beyond which the echo is

　　The current market for water level gauges generally includes principles such as electromagnetic waves, ultrasonic waves, and lasers (radar mud water level gauges), with priority given to radar mud water level gauges (electromagnetic waves); Ultrasonic waves are mechanical waves, while millimeter waves and lasers are electromagnetic waves. Ultrasonic waves are greatly affected by factors such as temperature, and lasers are also affected. Millimeter waves (radar mud level gauges) have strong all-weather capabilities and are typically suitable for monitoring mud level and debris flow disasters at field stations.

　　The selection of mud water level timing should mainly consider the following aspects

　　1: Launch angle, the smaller the angle, the better

　　2: Power consumption, the lower the power consumption, the better

　　3: Protection level, protection level IP68

　　4: Frequency, 80G ≥ 26G ≥ 24G ≥ 60G

　　5: The lower the anti-interference ability, the better

　　HR7380 typeMud level gaugemain advantagesWhat is it?

　　Based on our self-developed CMOS millimeter wave RF chip, we achieve a more compact RF architecture, higher signal-to-noise ratio, and smaller blind spots.

　　The 5GHz working bandwidth enables the product to have higher measurement resolution and accuracy.

　　The narrowest antenna beam angle is 6 °, and the interference in the installation environment has less impact on the instrument, making installation more convenient.

　　Integrated lens design with exquisite volume.
