3 Reasons Jiwei Reliable Level Sensors Deliver Long-Term Value
Why Reliable Level Sensors Matter in Dairy Production
In dairy processing, the need for a reliable level sensor is not optional—it’s fundamental. From raw milk intake to cream separation, pasteurization, fermentation, and storage, precise level measurement ensures operational safety, product consistency, and hygiene compliance.
Level sensors that fail or drift over time can cause severe consequences:
- Product loss due to overfilling or empty tank operation
- Incomplete cleaning during CIP/SIP cycles
- Process interruption or contamination
- Energy inefficiencies in thermal processing
Jiwei addresses these issues with two specialized sensor solutions: the Ring-11 tuning fork level switch for point level applications, and advanced JWrada-31 radar level meters for continuous measurement. Each is engineered to perform reliably under the unique conditions of dairy production.
Ring-11: Precision Point-Level Detection
The Ring-11 tuning fork level switch is ideal for applications where simple, reliable point-level monitoring is required. It’s designed to detect either high or low-level thresholds and is commonly used in tanks and pipelines handling milk, cream, yogurt, or whey.
Features of Jiwei Ring-11:
- Compact fork design with a length as short as 69mm
- Stainless steel 316L wetted parts with polished sanitary finish
- Food-grade sealing materials suitable for contact with dairy media
- Immune to foam, condensation, or turbulence
- Suitable for harsh CIP/SIP cleaning cycles up to 280°C
- SIL2/SIL3 certifications for use in safety-related control loops
- NAMUR or relay output for flexible integration into PLC/DCS systems
Because it operates via mechanical resonance, the Ring-11 remains unaffected by changes in dielectric constant, density, or buildup on the probe—common issues in dairy tanks.
Radar Level Meters: Continuous and Accurate
For continuous level monitoring in larger tanks and silos, Jiwei’s radar level meters offer high-precision, non-contact measurement—ideal for milk storage tanks, pasteurization balance tanks, or ingredient silos.
Advantages of Jiwei JWrada Radar Level Technology:
- 80GHz FMCW radar ensures ultra-narrow beam angles and high resolution
- Measurement range up to 120 meters
- Bluetooth configuration via Jiwei Smart Control app for easy commissioning
- PTFE antenna optional for aggressive or hygienic cleaning environments
- Resistant to foam, steam, and temperature variations common in dairy processes
- 4–20mA/HART communication for continuous signal transmission
Radar is particularly advantageous in tall tanks or in applications where mechanical contact should be avoided. Its accuracy, reliability, and ease of integration make it a go-to choice for modern dairy plants focused on automation and traceability.
Engineered for Hygienic Dairy Environments
Hygiene is paramount in dairy processing. Jiwei sensors are designed with sanitary engineering principles, using food-contact-safe materials and construction that enables full sterilization during CIP/SIP cycles. Reliable Level Sensor
Design Features Supporting Hygienic Compliance:
- 316L stainless steel wetted surfaces with surface roughness ≤0.5 μm
- Sealing components selected based on resistance to dairy acids, alkalines, and heat
- Crevice-free construction to avoid bacterial growth
- Fast temperature recovery after cleaning cycles for minimal downtime
