The KKITE LE65K series millimeter-wave radar level/liquid level gauge is designed for complex industrial conditions. It breaks through the 0.08 m near-field blind zone to achieve a 20 m long-range coverage, with IP67 protection for the entire unit, enabling zero-interference measurement in heavy rain, dust, and dense fog. Its core performance indicator is locked at ±1 mm absolute error, and its output interfaces cover PNP/NPN/4-20 mA/0-10 V/RS485, directly compatible with both new and old control systems.

Industry Pain Points: Three Major Failures of Traditional Measurement in Complex Conditions

The three most common ranging solutions in industrial settings often fail miserably in real-world environments:

* Ultrasonic: Severely affected by moisture, resulting in fluctuating readings and unstable readings;

* LiDAR: Rapid signal attenuation in dusty environments, frequently triggering failure alarms;

* Mechanical float: Prone to jamming and corrosion due to prolonged contact with corrosive media, leading to extremely high maintenance costs.

When measurement errors directly translate to downtime, traditional solutions have reached their limits.

Technical Core: 78 GHz FMCW – How to Achieve Penetrating Precision?

The LE65K employs a 76–81 GHz Frequency Modulated Continuous Wave (FMCW) millimeter-wave radar system. Its frequency, higher than the traditional Ku band, provides stronger long-range target detection capabilities. It exhibits no signal attenuation even in high dust concentrations of 50 g/m³, boasts an extremely narrow 8° beam angle (industry average 15°), concentrated energy, smaller blind zones, and stronger anti-interference capabilities. It has achieved multiple certifications including IP67, IEC 62561, and SIL2, ensuring reliability across the entire chain from hardware to algorithms.

Technical Principle: Why are Millimeter Waves More Suitable for Industrial Measurement?

Millimeter-wave radar offers unparalleled advantages in industrial measurement compared to ordinary microwave pulse radar and guided wave radar:

· Extremely narrow beam provides higher spatial resolution;

· Non-contact measurement eliminates the risk of mechanical wear;

· Strong penetration allows it to maintain stable echoes even in environments with smoke, dust, and steam.

Suitable for all-weather level/liquid level monitoring in water and wastewater, mining, mineral processing, metallurgy, and public utilities.

Extreme Testing: Making Rainstorms Computable Data

Even under a rainfall intensity of 75 mm/h, the LE65K still stably outputs continuous liquid level data. Through time-domain filtering of millimeter-wave signals and intelligent anti-interference algorithms, extreme weather is transformed from a "measuring no-go zone" into a "computable operating condition." In actual deployment cases, early warning response speed has increased by 40%, securing a critical time window for flood control and drainage.

Comprehensive Perception: A Hydrological Intelligent Decision-Making System with Multi-Source Data Fusion

The KJIT LE65K is not a single sensor, but rather the sensing front end of a "comprehensive perception, unified network collaboration" system:

·A-end: Real-time radar water level monitoring;

·B-end: Pipeline load calculation;

·C-end: Linkage with flood warning system.

Real-time linkage of data from these three ends forms a closed-loop decision-making process. After deployment at a drainage management center, the early warning response speed during the 2024 flood season increased by 40%. Water Treatment Scenario: Millimeter-Level Precision Reconstructs Water Purification Processes

In the dissolved air flotation (DAF) process, ±1 mm level water level control directly determines dissolved air efficiency and suspended solids removal rate. The LE65K achieves the following by precisely controlling the DAF tank level to ensure optimal air inlet pressure:

· 18% improvement in DAF process efficiency;

· Sludge reduction, setting a precision benchmark for the entire water purification process.

Enabling System: From Single-Point Measurement to Process Closed-Loop

KJIT's millimeter-wave radar empowerment system, centered on "precise radar level control," streamlines the water treatment process chain:

DAF inlet pressure optimization → Precise sludge discharge cycle adjustment → Suspended solids removal rate +18% / sludge moisture content -5%

This achieves comprehensive empowerment through closed-loop water level control in the flotation process and sludge level-linked sludge discharge in the sedimentation tank.

Reliability Commitment: A Three-Dimensional Assurance System for Worry-Free Operation and Maintenance

Kaigate has built a "full-lifecycle reliability empowerment" system for the LE65K:

• Hardware Assurance: IP67 protection, wide-temperature design, corrosion-resistant materials;

• Algorithm Assurance: Intelligent echo analysis, adaptive environmental filtering;

• Service Assurance: Full lifecycle technical support and rapid response.

This three-dimensional approach ensures worry-free operation and maintenance from installation to decommissioning.

A good radar not only measures, but also measures accurately, withstands heavy loads, and calculates precisely.
