Product Name:Vibration/Steel Wire Piezometer

Vibration/Steel Wire Piezometer

Application

Vibration/Steel Wire Piezometer

Product Description:

Model: KYJ
 
Working principle
The VW Piezometer operates on the principle that a tensioned wire, when plucked, vibrates at its resonant frequency. Around the wire is a magnetic coil which when pulsed by a vibrating readout or data logger interface plucks the wire and measures the resultant resonant frequency of vibration. A change in distance between the anchor and the diaphragm is related to pressure differentials and can be converted to a kPa reading.
Temperature information can be used if logging regularly to determine swift temperature changes during which pressure readings may be exaggerated
 
Features
Reliable long-term performance
Rugged, suitable for demanding environments
High accuracy
Insensitive to long cable lengths
All non-drive-in models can have threaded adaptors to customer specifications
Applications
Pore pressure measurement in soils and rocks
Fluid pressures in hydro-fracture and pump tests
 
Structure
Permeable ring +sensitive membrane+seal case+signal wire+vibration wire+strong vibration eletromagnetic
Caculate
When pore piezometer loads pressure of water, the voltage "P" and output frequency "F" as below : 
P = kF20-F2i
