With high-precision measurement, excellent environmental adaptability, and intelligent functions, 80G radar level transmitters are becoming an indispensable key technology in the environmental protection and energy sector.
In the environmental protection and energy industry, efficient and accurate level measurement is crucial for ensuring the continuity, safety, and economy of the production process. Traditional level measurement technologies often face challenges under complex working conditions, and the emergence of 80GHz high-frequency radar level transmitters provides a perfect solution to these problems. It not only achieves high-precision measurement (up to ±1mm) but also can withstand extreme conditions such as high temperature, high pressure, dust, and steam, injecting new impetus into environmental protection and energy applications such as waste incineration power generation and chemical production.
The production environment of the environmental protection and energy industry is usually extremely complex and harsh. In waste incineration power plants, waste storage bins are filled with biogas, corrosive gases, and pungent odors generated by fermentation. The irregular state of materials makes it difficult for traditional measuring equipment to work accurately. Any measurement error may affect the normal operation of the incinerator and even cause potential safety hazards.
Various reaction kettles and storage tanks in chemical production enterprises also have extremely high requirements for liquid level measurement. Many factors such as corrosive media, small storage tanks, high temperature and high pressure, and interference from stirring blades are testing the technical content and practicality of level measurement products.
80G radar level transmitters adopt Frequency-Modulated Continuous Wave (FMCW) technology, with a frequency as high as 80GHz. This high-frequency signal brings multiple advantages: an extremely narrow beam angle (minimum 3°), stronger signal strength, a smaller measurement blind zone (minimum 1-2cm), and higher measurement accuracy (±1mm).
Its antenna system is made of corrosion-resistant PTFE material or high-temperature resistant ceramic material. The specially designed "triple protective sealing" structure enables it to operate safely under harsh working conditions with a maximum temperature of 450°C and a maximum process pressure of 160bar.
The intelligent signal processing system can automatically identify and eliminate interference signals caused by tank vibration and liquid fluctuation, further improving measurement accuracy and reliability.
A chemical enterprise in Shandong faced challenges in liquid level measurement of its DMF (Dimethylformamide) tank. The height of the DMF tank is only 30cm, making it impossible for most instruments to be used normally. Conventional 26G radars have a blind zone of 20cm, which cannot meet the requirements of small-range working conditions. Although magnetostrictive level transmitters have a smaller blind zone, their measuring rods cannot work normally after coming into contact with the corrosive medium.
After selecting the 80G frequency-modulated radar, it perfectly solved the measurement problem of small-range working conditions with a blind zone of only 1-2cm. The antenna adopts anti-corrosion treatment with PTFE flanging, ensuring that all liquid-contacting parts will not be corroded by the medium and guaranteeing long-term stable operation.
A food additive factory in Jiangsu faced multiple challenges such as high temperature (130°C), stirring, foam, and steam in the liquid level measurement of its reaction kettle. The customer had previously tried multiple types of level transmitters, but none of them could measure the correct liquid level stably.
After selecting the NYRD series 80G high-frequency radar level transmitter, with settings by professional technicians, it could normally measure the liquid level height. When there was foam on the liquid surface in the tank and stirring was in progress, false echo learning was carried out during empty tank stirring, ensuring that real-time echo signals could be received when measuring the liquid level.
80G radar level transmitters provide a comprehensive solution for solving level measurement problems under complex working conditions in the environmental protection and energy industry.
For working conditions with strong dust, an integrated air-purged antenna can be selected. It is convenient to use by connecting to an air source and can well solve the impact of material adhesion on measurement.
For corrosive and pressurized occasions, a stainless steel fully PTFE-lined sealed flange antenna can be used, with an integral lens antenna type with a polytetrafluoroethylene sealing surface, ensuring that corrosive gases and liquids do not enter the interior of the equipment.
For ultra-high temperature occasions above 200°C, a high-temperature isolation device can be installed. For flammable and explosive hazardous working conditions, a dual-cavity explosion-proof radar can be selected, with complete intrinsic safety and flameproof explosion-proof types to ensure safe and reliable operation.
The value brought by 80G radar level transmitters is obvious: production efficiency is significantly improved, on-site measurement data remains stable for a long time, providing a solid guarantee for the precise control of the production process. At the same time, the workload of manual measurement is greatly reduced, effectively lowering labor costs and avoiding safety risks of manual operation in harsh environments.
As the environmental protection and energy industry moves towards intelligence and digitalization, 80G radar level transmitters are also continuously innovating and upgrading. The new-generation products support a variety of communication protocols, such as PROFIBUS PA, HART, and the innovative Ethernet-APL digital communication protocol, enabling bidirectional and fast data transmission with asset management systems.
The Heartbeat Technology equipped in the instrument makes all equipment statuses and process parameters clear at a glance. Users can generate equipment status reports online, easily realize process monitoring, and identify conditions such as foam, adhesion, and abnormal voltage in the circuit at an early stage, thereby achieving preventive maintenance and preventing losses caused by unexpected shutdowns.
It supports mobile phone Bluetooth debugging, remote debugging, and remote upgrade functions, which greatly simplifies the operation and maintenance process. The instrument is equipped with a Chinese debugging wizard function, allowing on-site instrument management personnel to easily get started without special training. In case of a fault alarm, the fault cause and corresponding treatment measures will be displayed.
With the acceleration of the industrial digitalization process, 80G radar level transmitters are continuously integrating more powerful intelligent functions. Heartbeat Technology makes equipment statuses and process parameters clear at a glance, and remote debugging and upgrade functions greatly reduce operation and maintenance costs.
In the future, in the intelligent transformation of the environmental protection and energy industry, 80G radar level transmitters will continue to serve as a key enabling technology, promoting the industry towards a safer, more efficient, and greener direction.
