Product - Vibrating Wire Piezometer
- Brand
- Geositter
- Description
This vibrating wire piezometer is an advanced instrument designed for precise measurement of pore water pressure in subsurface environments. Utilizing proven vibrating wire technology, it provides highly accurate and reliable data essential for geotechnical and environmental monitoring applications. The sensor's robust design ensures long-term stability and performance in challenging subsurface conditions.
Detailed Description
- High-Precision Measurement Technology: Employing vibrating wire technology, this piezometer accurately measures pore water pressure. Changes in pressure deflect a diaphragm, altering the resonant frequency of a vibrating wire. This frequency shift, detected by an electromagnetic coil, is precisely translated into pressure readings, ensuring high sensitivity, accuracy, and long-term stability.
- Reliable Data Transmission: Digital signal transmission minimizes signal distortion and noise interference over long distances.
- Durable and Waterproof Construction: The piezometer features a robust, waterproof design for reliable performance in demanding subsurface conditions.
- Rapid Data Acquisition: The pulse excitation method enables fast and efficient pressure measurements.
- In-situ Temperature Compensation: Integrated temperature sensing at the measurement point provides real-time temperature compensation for enhanced accuracy.
- Integrated Data Acquisition System: A user-friendly, integrated data acquisition system displays pressure and temperature readings, supporting automated measurements and wireless remote monitoring.
