KLD804 4-20mA / RS485 76mm Lens Antenna Radar Level Sensor for
Liquid and Solid Medium
Introduction
The 80G lens radar level sensor adopts 80GHz high-frequency radar
technology, and focuses the radar waves on the surface of the
material through the lens and antenna. When radar waves encounter
materials, reflections and scattering occur. The reflected and
scattered signals are received through the antenna and receiver,
and then converted into material level information.
Compared with the traditional level measurement method, the 80G
lens radar level sensor has higher measurement accuracy and wider
measurement range. Lens focusing technology can reduce interference
and improve signal-to-noise ratio, thereby improving measurement
accuracy. The 80GHz high-frequency radar technology can penetrate
the dust mist and steam of materials, and is suitable for level
measurement in harsh environments such as high temperature, high
pressure, flammable and explosive.
Feature
- The measurement accuracy can reach ±2mm.
- The smaller antenna size satisfies the measurement of more working
conditions.
- A variety of lens antennas, smaller launch angles, more
concentrated energy, stronger echo signals, and higher reliability
than other radar products under the same industrial and mining
conditions.
- It has stronger penetration and can be used normally in the case of
adhesion and condensation.
- The dynamic signal range is larger, and the measurement of low
dielectric constant media is more stable.

Hoisting Installation
At present, radar level sensors are widely used in many industries,
such as metallurgical industry, coal industry, cement industry,
petrochemical industry, etc. These industries are subdivided into
many specific occasions:
Metallurgical industry
Metallurgical industry applications mainly include iron ore,
limestone raw materials, and raw coal bunkers in steel plants;
carbon powder, aluminum ore, and coal powder in aluminum plants.
coal industry
The main applications in the coal industry include raw coal, clean
coal, cinder, coal powder, and coal-containing sewage in coal
washing plants.
Power Industry
The main applications in the power industry include
desulfurization, lubricating oil, mud, raw coal bunkers, fuel
bunkers, etc.
Water industry
The main applications in the water conservancy industry include
lakes, rivers, reservoirs, open channels, wetlands, shoals, tides,
underground water pipe networks, ditches containing a large amount
of floating matter and sediment, places where a large amount of
aquatic plants are produced, and areas where flash floods occur
frequently.
Petrochemical industry
The main applications in the petrochemical industry include crude
oil, hydrogen tincture, dirty oil, and sludge in oil production
plants, settling tanks, sewage tanks, and drilling mud tanks in oil
fields, liquefied natural gas, condensed water in liquefied gas
stations, oil storage depots, and biodiesel Gasoline, diesel, and
tar from the factory, urea melt, ammonia water from the compound
fertilizer factory, various chemical products, high-temperature,
high-pressure, highly corrosive media, and toxic products from the
chemical factory.
