Hard Material Piezo Ceramic Disc for DVL Doppler Velocity Logs
WuHan Piezohannas Tech.Co .,Ltd is a manufactuer of piezoelectric ceramics ,ultrasonic transducers and some other ultrasonic deivce with strong technology force.With a quality management system and research & development sector,our products are extensively used in most applications.
- Piezo Material: PCrN-4
- Dimensions: Φ20× 3mm
- Resonant Frequency: 700KHZ
- Applications: Doppler velocity logs (DVL), Acoustic Doppler Instrument
range of piezo disc to produce:
Diameter: 2mm-120mm
Thickness:0.1mm-30mm
The value of the DVL into such a solution is that it has zero mean bias and does not drift. The DVL is the critical because without it, the position would drift substantially with time. The DVL helps limit the cumulative errors of a complete navigation solution.
