Radar Level Sensor With Horn Antenna (80GHz FMCW)

The Radar Level Sensor with Horn Antenna is a modern mainstream 80GHz FMCW (Frequency Modulated Continuous Wave) non-contact level measuring instrument, specially optimized for solid powder, granular materials and complex dusty industrial working conditions. Different from traditional 26GHz pulse radar which suffers from low accuracy and outdated performance, this high-frequency 80GHz radar adopts advanced FMCW technology paired with a professional PTFE horn antenna structure, achieving ultra-narrow beam transmission, minimal blind zone and stronger environmental adaptability.

Compared with conventional lens antenna radar sensors, the upgraded horn antenna design features smoother discharge structure and superior anti-sticking performance, effectively reducing material accumulation and dust coverage on the antenna surface. It delivers stable and high-precision continuous level measurement for various silos, storage tanks and process vessels, unaffected by dust, slight condensation and medium dielectric changes. As the mainstream solution for modern industrial solid and complex liquid measurement, it perfectly solves the unstable measurement problems of low-frequency radar sensors.

Traditional low-frequency 26GHz pulse radar has gradually faded out of mainstream industrial applications due to wide beam angle, large blind zone, low precision and poor anti-interference ability. Most ordinary 80GHz radar sensors adopt lens antenna, which is prone to material adhesion and dust buildup in long-term powder measurement scenarios, resulting in signal attenuation and measurement drift.

This 80GHz FMCW Radar Level Sensor with Horn Antenna integrates the advantages of high-frequency radar and optimized horn-type antenna structure. The 3° ultra-narrow beam accurately avoids tank internal obstacles, supports long-distance and high-precision detection, while the open horn structure prevents material deposition and ensures long-term clean signal transmission. It abandons the compromise design of universal sensors and focuses on solving core pain points in solid material measurement, becoming the preferred upgraded replacement for traditional low-frequency radar and ordinary lens radar in modern industrial projects.

Mainstream 80GHz FMCW High-Frequency Technology

Adopts 76~81GHz mainstream FMCW frequency band, featuring short wavelength, concentrated signal energy and ultra-high measurement accuracy. Far superior to traditional 26GHz pulse radar in stability, resolution and anti-interference performance, fully meeting modern industrial high-precision measurement standards.

Optimized PTFE Horn Antenna Anti-Adhesion Design

Equipped with integral PTFE horn antenna, featuring smooth surface and unobstructed radiation structure. It effectively avoids powder accumulation, material sticking and scaling problems common with lens antennas, maintaining stable signal emission and reception in long-term dusty working environments and reducing manual maintenance frequency.

Ultra-Narrow Beam & Minimal Blind Zone

3° narrow beam angle effectively bypasses tank walls, support frames and internal obstacles, greatly reducing false echoes. Ultra-small measuring blind zone adapts to short-distance and high-precision detection requirements, covering more comprehensive measuring ranges than traditional low-frequency radar.

Strong Dust & Condensation Resistance

High-frequency FMCW signal has strong penetration, stable operation in heavy dust, slight steam and condensation environments. The measurement performance is not affected by medium density, viscosity and dielectric constant changes, adapting to harsh solid material working conditions.

Non-Contact Maintenance-Free Operation

Non-intrusive non-contact measuring method, no contact with measured media, no wear, no blockage. It realizes long-term maintenance-free operation, effectively reducing equipment operation and maintenance costs for industrial enterprises.

Industrial Explosion-Proof & Sealed Protection

Comes with intrinsic safety explosion-proof certification, suitable for flammable and explosive industrial sites. IP67 high-level sealed housing resists dust, moisture and environmental corrosion, ensuring stable operation in outdoor and harsh workshop environments.

1. This 80GHz horn antenna radar is mainly designed for solid powder, granular materials and conventional liquid measurement, not applicable for ultra-strong corrosive fluorine-containing media.

2. Although the horn antenna has excellent anti-adhesion performance, it is not recommended for working conditions with severe material impact and heavy sticky deposits for long-term operation.

3. For high-temperature and high-pressure extreme working conditions, please select customized high-spec industrial radar models.

Q1: What is the difference between 80GHz horn antenna radar and traditional 26GHz radar?

Traditional 26GHz pulse radar is an outdated low-frequency solution with wide beam, large blind zone and low accuracy. The 80GHz FMCW horn antenna radar is the current mainstream industrial model, featuring narrow beam, minimal blind zone, higher accuracy and stronger anti-interference ability. Meanwhile, the horn antenna avoids material adhesion defects of ordinary lens radar, making it more suitable for solid dust working conditions.

Q2: Why choose horn antenna instead of lens antenna for solid measurement?

PTFE horn antenna adopts open radiation structure with smoother and more fluid surface, which is not easy to accumulate powder and dust. Lens antenna has concave and closed structure, prone to material deposition and signal attenuation after long-term operation. Horn antenna is more professional and reliable for solid silo measurement.

Q3: Can this sensor work in heavy dust environments?

Yes. The 80GHz high-frequency FMCW signal has strong penetration capability, and the horn antenna structure will not block dust diffusion. It can maintain stable measurement performance in long-term heavy dust working conditions.

Q4: Is this model compatible with flange and thread installation?

Yes. It supports both flange and thread process connections, adaptable to various standard tank nozzles and on-site installation requirements.
