The HQ-8260L high-frequency pulse radar level gauge is resistant to condensation, crystallization, material buildup, and dust, with a concentrated beam. The principle of the HQ-8260L pulse radar level gauge - universal joint is that the antenna of the radar level gauge emits extremely narrow microwave pulses, which propagate in space at the speed of light. When these pulses encounter the surface of the measured medium, part of their energy is reflected back and received by the same antenna. The time interval between the emitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the measured medium, allowing the calculation of the distance from the antenna to the surface of the measured medium.
The HQ-8260AH purge-type planar radar level gauge comes with a built-in purge system, making it suitable for use in harsh environments with strong dust, steam, and material adhesion, as well as in material measurement conditions with conical tank bottoms.
The HQ-8260W teardrop-shaped radar level gauge operates within the frequency band of 24G~26GHZ. It is a non-contact radar based on the frequency modulation continuous wave principle, featuring superior signal processing capabilities. Compared to traditional radars, it exhibits stronger measurement effectiveness and repeatability. It can measure the distance, level, and volume of liquids, slurries, or solids. Compared to pulse radars or general radars on the market, it possesses characteristics that these other radars do not have.
The HQ-8260P paraboloid antenna consists of a reflector and a feed source located at its focal point, forming an axisymmetric paraboloid-shaped structural antenna. The main advantage of the paraboloid radar level gauge is its high directivity, functioning like a searchlight or flashlight, focusing microwaves in a narrow beam towards a specific direction. Due to the ability of the HQ-8260P paraboloid radar level gauge to produce a narrow beam width and directionality, it can perform measurements effectively even when there are many interfering objects inside the tank wall, without being affected by false echoes from interfering objects such as steps. It is suitable for measuring media with wide ranges, high dust, high temperatures, and low dielectric constants in the cement, power, and steel industries.
The HQ-8260AZ-F hygienic self-aiming planar radar level gauge features a fully sealed PTFE antenna that is corrosion-resistant, making it suitable for use in environments with strong dust, steam, material adhesion, and in cone-shaped tank bottoms for material measurement.
The HQ-8260AS-H high-temperature planar radar level gauge is a wide-range continuous frequency modulation radar used for measuring solid and liquid materials/level measurement. The JLRS560 is the most convenient and reliable radar level gauge on the market today. It operates at a frequency of 78GHz, creating a very short wavelength that produces excellent signal reflection for almost all solid materials, even achieving good measurement results on very steep and undulating irregular material surfaces.
The HQ-8260AG2 radar product is specifically designed for various complex measurement environments in industrial processes, such as tanks with condensate, sediment, adhesive substances, steam, or dust adhesion. Compared to other radar level measurement products, this product does not require purging, is not affected by material buildup, and offers significant economic benefits. It is suitable for extremely harsh working conditions such as strong dust and steam, as well as storage tanks with special processes like stirring and heating rods.
The HQ-8260AS planar radar level gauge can be used in measurement conditions with strong dust, steam, material adhesion, and conical tank bottoms. The 26GHz planar antenna consists of an array of 64/128 small antenna units, each with independent electromagnetic wave transceiving capabilities; thus, it has strong penetration ability against steam/dust. This is similar to the principle that large fish cannot pass through a fishing net, but small fish can, and small fish can freely enter and exit the net. The planar antenna formed by the array of 64 small antennas has a higher gain value than a horn with the same aperture area, with a synthetic beam angle of about 11 degrees; the planar antenna formed by the array of 128 element antennas can have a beam angle as small as 6 degrees.
The HQ-8260AZ flat self-aiming alignment radar level gauge is suitable for use in measurement conditions involving strong dust, steam, material adhesion, and conical tank bottoms.
The HQ-8260H anti-corrosion rod-type radar level gauge features a sealed, anti-corrosion antenna designed for small-sized liquid tanks, addressing high-precision measurement of corrosive liquids.
The HQ-8430S radar water level gauge for water conservancy and hydrology is designed for measuring the water levels of rivers, lakes, reservoirs, and mountain ponds in water conservancy and hydrology sites. The effective measurement range of the product is 30 meters; the setting of water level full point and zero point/current calibration/distance correction all adopt one-button calibration, which is convenient and simple; the measurement distance error is about ±15mm. The factory standard setting parameters of the product are: measurement range from 1.0 meters to 30 meters; current output range: 4mA to 20mA; digital communication: RS485 Modbus protocol communication output (9600 baud rate/8 bits). This product can be widely used in water conservancy and hydrology sites, and can also be used for industrial site material level/liquid level measurement.
HQ-9127120GHz radar level gauge is an industrial metrology-grade radar in the terahertz band, featuring high precision, high reliability, and high cost-effectiveness. It offers high-precision non-contact measurement of material and liquid levels, with an extremely narrow beam and strong detection and penetration capabilities thanks to its lens antenna. It supports standard 4~20mA current output, standard HART, MODBUS, and PROFIBUS bus protocol communication, and features a TFT LCD color display that is sunlight readable, allowing direct operation under direct sunlight.
The HQDB60 guided wave radar level gauge is suitable for various containers, storage tanks, silos, etc., with complex process conditions, and is not affected by changes in the physical properties of the measured medium. It employs external measurement and two-wire technology. The HQ-51L intelligent radar level gauge is suitable for explosion-proof applications.
