The Frankstar Vibrating Wire Piezometer is designed for accurate, long-term monitoring of pore water pressure and water levels in soils, rock, and embankment structures. Built with high-grade stainless steel, it ensures exceptional stability and resistance to harsh underground and aquatic environments.
Key Features & Technical Highlights:
- High Precision & Long-Term Stability: Frequency output allows signal transmission over long distances without degradation.
- Built-in Temperature Transducer: Allows for automatic temperature compensation and thermal correction.
- Corrosion-Resistant Construction: Rugged stainless steel housing and IP68 waterproof rating for fully submerged operation.
- Multi-Filter Options: Low air-entry or high air-entry sintered stainless steel filter options to suit various soil conditions.
- Strong Compatibility: Easily connects to automated data acquisition systems (MCU/Dataloggers) and wireless IoT telemetry systems.
Applications:
- Geotechnical and civil engineering site investigations
- Dam, dike, and embankment safety monitoring
- Slope stability assessment and landslide monitoring
- Tailings ponds, deep excavations, and foundation pit safety management
