Radar Level Sensor For Solids | 76-81GHz Non-Contact Radar Level Transmitter

Level measurement in solid silos always faces tough challenges including heavy dust, uneven material surfaces, build-up and long measuring distances. Ordinary low-frequency radar suffers from wide emission angles, severe signal attenuation and larger blind zones, which easily trigger unstable readings. This high-frequency solid radar level sensor features a narrow 3° beam angle, enabling signals to travel along the silo centre and effectively bypass silo walls, support beams and material accumulation. The robust signal output ensures stable detection even within heavily dusty environments. XYRD9093 is fitted with an integrated PTFE filled lens antenna paired with a purgable universal flange. Operators can adjust antenna orientation flexibly to match conical silo structures. The optional purge function prevents dust buildup on the antenna surface, cutting down routine maintenance work. Users gain flexible access to configuration methods: local LCD keypad operation, Bluetooth programming tools and 5G remote commissioning. Multiple signal output options satisfy diverse industrial control systems. When your working conditions differ from the configuration of XYRD9093, our engineering team can recommend other matched radar sensor models.

Ultra-Narrow 3° Beam Angle

The tight emission angle reduces signal interference from silo internal obstacles. It adapts well to tall conical silos and avoids false echoes caused by wall attachments and supporting structures.

Powerful Signal & Minimal Blind Zone

Strong radar signal penetrates dense dust clouds. The optimized circuit design achieves a small blind zone, supporting reliable measurement for short-range and long-range solid material monitoring.

Integrated PTFE Filled Lens Antenna

78mm PTFE monolithic filled lens antenna prevents material adhesion. The compact structure delivers stable signal transmission without signal distortion.

Adjustable Antenna with Purge Capability

Universal purgable flange allows flexible antenna angle adjustment. Air purge interface removes dust accumulation on the antenna, suitable for long-term continuous operation in powder silos.

Multiple Commissioning Options

Supports local LCD display and keypad setup. Bluetooth programming device and 5G remote network debugging are available for convenient on-site and off-site parameter configuration.

High Measuring Accuracy

Maintains stable precision of ±5 mm, supporting accurate inventory management for bulk solid raw materials.

Diversified Power & Signal Output

Standard two-wire 4-20mA / HART; customized four-wire version, RS-485 Modbus communication optional. Supports DC24V and AC220V power supply to meet different site power schemes.

Intrinsically Safe Explosion-Proof Design

Certified Ex ia IIC T6 Ga, suitable for level monitoring of flammable dust and combustible solid materials in hazardous production zones.

Reliable Outdoor & Silo Deployment

IP67 protection grade blocks dust intrusion and water splashing, stable for indoor silo buildings and outdoor bulk storage facilities.

Chemical Solid Raw Material Warehouses

Intrinsically safe explosion-proof version works for combustible powder and granular chemical raw material storage tanks.

Q1: What advantages does this solid radar level sensor have over general liquid radar transmitters?

A: This model is optimized for solid bulk materials. The 3° narrow beam angle, anti-dust lens antenna and adjustable purging flange are targeted for silo environments with heavy dust and uneven material surfaces. Ordinary liquid radar usually has wider emission angles and lacks anti-dust structures, which are prone to unstable readings in solid silos.

Q2: Is the antenna angle adjustable after installation?

A: Yes. Equipped with universal adjustable flange, users can fine-tune antenna orientation on site to align the radar signal toward the material surface and avoid obstacles inside the silo.

Q3: Does the purge function come as standard configuration?

A: The flange reserves the purge interface. Air purge assembly can be selected as an optional accessory if the site has severe dust adhesion.

Q4: Can I debug the radar remotely without going to the site?

A: Apart from local LCD and Bluetooth operation, 5G remote network debugging is available as an option, supporting remote parameter adjustment and fault diagnosis.

Q5: What if the 120m measuring range cannot meet my silo height?

A: This page introduces XYRD9093 with maximum measuring range of 120 meters. We provide multiple radar models with different ranges and antenna forms. Send your silo size and material parameters for targeted model recommendation.

Q6: Can this radar be used for flammable dust hazardous areas?

A: Yes, it carries Ex ia IIC T6 Ga intrinsically safe explosion-proof certification, meeting application requirements for most combustible dust and flammable solid working zones.
