Vibration Wire Piezometers

Vibration Wire Piezometers 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
