Strong local support: Faster delivery, localized technical service, and spare parts availability from China.
Customization: Ability to tailor probes, antennas, and software for specific Chinese industrial needs.
In industrial liquid level and solid level measurement, radar level meters have become a mature technology. However, the real challenges on engineering sites have never been “whether it can measure,” but rather: Can the echo remain stable under steam, foam, and high dust conditions?
Will there be frequent signal loss during stirring or violent fluctuations caused by material feeding/discharging?
Can it operate reliably for the long term in high-temperature, high-pressure, and highly corrosive media?
Does installation and commissioning always require climbing to height and opening the tank cover? Does maintenance always require on-site visits?
Shaanxi Shengke Electronic Technology Co., Ltd., SKE starting from these real pain points and relying on its independently developed 80GHz millimeter-wave radar core technology, has created the SK-R800 Series High-End and SK-R800 Series Economic radar level sensors, delivering solid technical solutions.
I. SK-R800 Series High-End Radar Level MeterDesigned for harsh working conditions, driven by real-world performance.1. 80GHz Millimeter-Wave Radar: A leap in engineering performance
The SK-R800 high-end model adopts 80GHz FMCW (Frequency Modulated Continuous Wave) radar technology, with a wavelength of only about 3.75mm. It is equipped with various antenna types including lens antennas and horn antennas, offering a maximum range of up to 120 meters. The engineering advantages of the high frequency are clearly demonstrated as follows: Extremely narrow beam angle as low as ±1.9°, effectively avoiding interference from tank walls, brackets, agitators, and other internal structures.
Highly concentrated energy, resulting in minimal signal attenuation in high-dust environments (such as cement and fly ash silos) and strong steam conditions, enabling stable capture of true material level echoes.
Millimeter-level resolution with accuracy up to ±2mm. The fastest dynamic sampling rate reaches 0.6 seconds per measurement, allowing it to detect small fluctuations in liquid level and respond quickly.
2. Echo Locking Algorithm: Locks onto the true echo, unafraid of complex interference
Vortexes from agitators, violent fluctuations caused by rapid material feeding/discharging, and multiple reflections from the tank bottom often occur simultaneously. The SK-R800 high-end radar level meter is equipped with a self-developed echo locking algorithm and dynamic echo tracking technology. It analyzes the echo curve in real time, automatically identifies and filters out false echoes from agitators, internal supports, and material buildup. Even during drastic level fluctuations, it firmly locks onto the true echo trajectory, completely eliminating signal loss. The built-in independent processing unit enables high-speed local computation, ensuring fast response and high reliability.3. Bluetooth Wireless Commissioning: Say goodbye to “must go on-site, must open the cover”
Traditional radar installation often faces challenges such as high-altitude work, confined spaces, explosion-proof and corrosion-proof environments, difficult operation, and high wiring risks. The SK-R800 high-end radar level meter comes standard with Bluetooth wireless debugging. Through the “RadarMe” APP (supporting iOS and Android), users can: Perform wireless scanning and quick pairing
Remotely configure range, medium type, and output mode
View real-time echo curves and trend graphs
Conduct fault diagnosis and maintenance reminders
Manage multiple meters centrally
Engineers no longer need to open the cover, add extra wiring, or use dedicated debuggers — all commissioning can be completed with just a smartphone. When abnormalities occur during operation, remote parameter modification and fault diagnosis can significantly reduce on-site visits and lower maintenance costs.4. High-Temperature, Explosion-Proof, Corrosion-Resistant, and High-Protection: These are not optional — they are standard
