The XYRD9095-NCR 80GHz hygienic radar level sensor is a dedicated non-contact level measuring solution designed specifically for high-sanitation industrial scenarios. Different from ordinary industrial radars focused on chemical and sewage measurement, this high-frequency FMCW radar features a flush PTFE lens and hygienic clamp connection, supporting CIP/SIP cyclic sterilization and zero-residue production requirements. It excels in stable measurement for viscous, low-conductivity, easily foamed and density-variable media that conventional level instruments struggle to detect accurately.

Food & Beverage Sanitary Processing

Ideal for continuous level monitoring of milk, cream, fruit juice, beer, syrup and purified water in sealed process tanks and storage vessels. Its ultra-narrow 8° beam angle effectively avoids false echoes caused by liquid stirring, splashing and surface foam during mixing and filling procedures. The residue-free PTFE surface ensures no medium accumulation, fully meeting food-grade hygiene standards for batch production and automatic filling control.

Pharmaceutical & Biotech Sterile Production

Perfect for precision level tracking in fermenters, formulation tanks, buffer solution containers and pharmaceutical solvent storage tanks. With ±3mm ultra-high accuracy and full vacuum-to-positive-pressure adaptability, it provides stable and repeatable liquid level data for sterile batching, biological fermentation and reagent configuration processes. Dual explosion-proof certifications also support safe measurement for workshops with flammable volatile liquids.

Complex Viscous & Low-Conductivity Media Conditions

This 80GHz high-frequency radar maintains excellent signal penetration for low-dielectric fluids, viscous syrup and turbulent mixing media. It solves common industry pain points such as unstable readings and data deviation caused by changing medium density, liquid viscosity fluctuations and stirring interference, ensuring consistent process control accuracy throughout production cycles.

High-Cleanliness Industrial Storage Tanks

Suitable for long-term level monitoring of low-conductivity raw materials and purified process water in closed sanitary tank systems. The IP67 fully sealed structure withstands frequent high-temperature washing and steam sterilization, delivering reliable 24/7 unattended level measurement for hygienic production lines.

• Sanitary Zero-Residue Performance Guarantee

All wetted parts adopt integrated flush PTFE lens structure without gaps, threads or dead corners. It tolerates repeated high-temperature CIP/SIP cleaning and various sanitary detergents, ensuring no medium residue, no cross-contamination and full compliance with food and pharmaceutical hygiene regulations.

• Ultra-High Precision & Stable Output Assurance

Factory-calibrated to maintain fixed ±3mm accuracy and ±1mm resolution across the full 0–20m measuring range. The optimized 76–81GHz FMCW continuous wave algorithm suppresses foam, turbulence and steam interference, guaranteeing stable and repeatable measurement even in dynamic production environments.

• Wide Temperature & Pressure Adaptability Guarantee

The sensor stably operates at process temperatures from -40℃ to 120℃ and process pressures of -0.1MPa to 2.0MPa, adapting to vacuum concentration, high-temperature sterilization and normal-pressure fermentation processes. IP67 full sealing prevents moisture, steam and dust intrusion.

• Explosion-Proof Safety & System Compatibility Guarantee

Certified with Ex iaⅡC T6 Ga and Ex db IIC T6 Gb dual explosion-proof standards, it can be safely installed in flammable and explosive hygienic workshops. Supporting 4-20mA+HART and RS-485 Modbus dual signals and 2/4-wire DC24V power supply, it achieves seamless connection with mainstream PLC and DCS systems.

• Low-Maintenance Long-Term Operational Quality

Non-contact radar measurement requires no contact with liquid media, eliminating wear, blockage and adhesion failures. The modular split design supports independent component inspection and replacement, greatly reducing downtime and daily maintenance costs for sanitary production lines.

Q1: What are the core advantages of this hygienic 80GHz radar compared with ordinary industrial radar sensors?

A: Unlike general-purpose radars designed for industrial sewage and chemical tanks, this model is professionally optimized for sanitary sterile production. It features a gap-free flush PTFE lens and hygienic tri-clamp connection that supports CIP/SIP sterilization. The 8° ultra-narrow beam minimizes blind zones and avoids tank wall interference, making it far more accurate and hygienic for small fermentation tanks and mixing vessels.

Q2: Can it measure viscous, foamy and low-conductivity food and pharmaceutical media?

A: Yes. Adopting high-frequency 76–81GHz continuous wave transmission, the sensor has strong anti-interference and signal penetration capabilities. It stably measures syrup, cream, beer, fermentation broth and other low-dielectric viscous media, and effectively filters foam and liquid level fluctuation during stirring and filling.

Q3: Is the sensor resistant to repeated high-temperature cleaning and sterilization?

A: Absolutely. The food-grade PTFE wetted surface withstands continuous high-temperature sterilization up to 120℃ and frequent chemical cleaning. The fully sealed IP67 structure prevents steam and cleaning fluid ingress, ensuring long-term stable operation in cyclic sanitary production environments.

Q4: What signal output and power supply modes are available?

A: It supports two mainstream industrial signal outputs: 4-20mA+HART for intelligent analog control and RS-485 Modbus for remote digital data transmission. Both 2-wire and 4-wire DC24V power supply modes are optional, compatible with most food and pharmaceutical factory automation systems.

Q5: Can this radar be used in explosive pharmaceutical workshops?

A: Yes. It is equipped with dual Ex ia and Ex db IIC T6 explosion-proof certifications, fully compliant with safety requirements for workshops with flammable alcohol, organic solvents and volatile gas environments.

Q6: Does changing medium density and viscosity affect measurement accuracy?

A: No obvious impact. Optimized for dynamic sanitary working conditions, the FMCW algorithm automatically adapts to density changes and liquid viscosity fluctuations, maintaining stable level accuracy during material filling, stirring and switching production batches.

Q7: Does this hygienic radar require frequent maintenance and calibration?

A: No routine calibration is needed. The non-contact measuring principle causes no medium adhesion or mechanical wear. Modular structure simplifies on-site inspection and component replacement, significantly reducing maintenance frequency and production line downtime.
