FWS-5 Oil Property Sensor
Product Introduction
The FWS-5 Oil Property Sensor is an innovative multi-parameter fluid monitoring sensor designed for continuous, real-time analysis of liquid properties. Utilizing patented tuning fork technology, it simultaneously measures viscosity, density, dielectric constant, and temperature, providing a comprehensive understanding of fluid condition and performance.
Unlike conventional single-parameter sensors, the FWS-5 evaluates the dynamic relationship between multiple physical properties, enabling more accurate assessment of lubricant quality, fluid degradation, contamination, and process stability. Its compact design, robust construction, and easy integration with host controllers make it suitable for demanding industrial and mobile applications.

Key Features
• Simultaneously measures viscosity, density, dielectric constant, and temperature
• Patented tuning fork sensing technology for high stability and repeatability
• Real-time online monitoring without interrupting system operation
• Wide operating temperature range from -40°C to +150°C
• Suitable for high-pressure pipelines up to 25 bar
• Fast response for continuous process monitoring
• Compact design for easy integration with PLCs and industrial controllers
• Excellent resistance to vibration and harsh industrial environments
• Reduces maintenance costs through predictive fluid condition monitoring
• Supports preventive maintenance and equipment reliability programs

Working Principle
The FWS-5 employs a patented tuning fork resonator immersed in the target fluid. Changes in the fluid's viscosity, density, and dielectric constant influence the resonant frequency and damping characteristics of the tuning fork. Advanced signal processing algorithms convert these variations into accurate physical property measurements while an integrated temperature sensor provides automatic compensation.
By continuously monitoring multiple fluid parameters simultaneously, the sensor enables early detection of oil degradation, contamination, oxidation, dilution, and changes in fluid composition, allowing operators to optimize maintenance schedules and improve equipment reliability.
