Frequently asked questions about dolphitech and our products
As above, this is also dictated by the laws of Physics. The target material’s characteristics and the frequency at which it is inspected by the dolphicam2 will dictate how deep the sound will be able to penetrate.
Annual calibration is done remotely by sending the calibration data file to email@example.com. There is a cost associated with this; please speak to your account manager for further information.
While the dolphicam2 platform can detect porosity, being able to quantify porosity data in each area is not available at this time. We plan to make this available in the near future.
The dolphicam2 platform does not allow you to customise the layout. However, users can manipulate the certain views like the gates, palette and measurement tools on the screen.
At this moment in time we do not. However, we take full advantage of the 128×128 Matrix array transducer in our current design probes to provide an incredible level of depth in real-time.
dolphicam2 is IP66 rated, which means it can withstand powerful dust and water jets. It would also be safe to immerse the front end of the TRM a few millimetres into water for immersed inspection.
The TRM enables front end control and digitizes the signals. The custom BlackBox does some signal processing, handles the processing of the signal data and communicates with the dolphicam2 Software that runs in the ToughPad.
To collect a pulse-echo-signal from a transducer element, an 70V pulse is excited on the transmitting electrode creating a sound field along the entire transmitting electrode, hence across all the receiver electrodes. The ultrasound goes through coupling and/or material and the reflected pulse is sampled on only one receiver electrode.
Ultrasonic physics will dictate what can be detected. Generally speaking, the higher the frequency of the ultrasonic waves, the higher the sensitivity. Higher sensitivity means you can see more. Simple; but this doesn’t mean you can see through everything!
The dolphicam2 platform can be used for NDT applications in industries such as automotive, aerospace and wind turbine.
The TRMs are incredibly ergonomic and easy to manipulate. If using a softer delay-line, this can conform to some curvature. For curvatures like pipes, etc. we hope to provide options for this in the near future.
Interchangeable delay lines are available on some TRM models.
