Product Details
Aumeascon’s 80GHz radar level transmitter uses high-frequency microwaves for non-contact level measurement, offering a highly focused beam, narrow angle, and wide bandwidth for excellent accuracy, even in challenging conditions like dust or obstructions, providing benefits like increased plant reliability, reduced engineering effort, and precise monitoring for liquids and solids in tanks and silos. Its principle involves measuring the time for an 80GHz signal to travel to the surface and back, converting this to distance, with superior performance over lower frequencies due to better signal reflection and object differentiation. it has become the preferred choice for liquid level measurement in complex working conditions It is widely used in energy, chemical, food, and other industries, bringing comprehensive value of efficiency improvement, risk reduction, and cost optimization for users.
How It Works
The 80GHz high-frequency radar level transmitter adopts Frequency-Modulated Continuous Wave (FMCW) technology. It emits 80GHz high-frequency microwaves and receives the reflected echo from the medium surface(medium or solid). The distance is calculated using the frequency difference with the core formula:
Liquid Level = Tank Height – (Echo Flight Time × Speed of Light ÷ 2)
The high frequency results in a very narrow beam angle (e.g., 8°) and small antenna size, allowing for installation in tight spaces and avoiding internal tank obstructions and concentrating energy to penetrate steam, dust, and other interferences for high-precision measurement.
Technical Features and Key Advantages
1.Ultra-Narrow Beam Angle: The beam angle is only 3°-5°, avoiding obstacles like agitators and heating pipes inside containers. Ideal for small-diameter tanks or installation near tank walls.
2.Millimeter-Level Precision: Measurement accuracy reaches ±2~5mm, It can detect weak signals from low-dielectric-constant media (ε > 1.4, e.g., liquefied gas).
3.Strong Anti-Interference Capability: False echoes are filtered via FFT + echo tracking algorithms. It can penetrate high-temperature oil vapor, foam, and dust, operating stably in vibration, high-temperature (-40℃~200℃), and high-pressure environments.
4.Maintenance-Free Design: Non-contact measurement with antennas made of corrosion-resistant materials (PTFE, Hastelloy). Some models feature self-cleaning coatings to prevent material buildup and corrosion, with a maintenance cycle of up to 5
5.Small Dead Zone: Allows the vessel to be filled nearly to the antenna.
6.Compact Antenna: Small antenna size (e.g., PEEK lens) simplifies installation, sometimes allowing for simple threaded connections.
7.Fewer Installation Issues: Narrow beam minimizes reflections from tank walls or internals, reducing false readings.
