Frequently asked questions about dolphitech and our products
This is dictated by the ability of the material to transmit ultrasound. The target material’s physical and chemical properties, as well as the ultrasonic frequency chosen, will all influence the dolphicam2’s penetration depth and its corresponding maximum inspection thickness.
Annual calibration is achieved remotely with our simple three step process. First, the user generates a calibration file on their system using the automatic annual calibration tool. Second, the user sends this calibration file to firstname.lastname@example.org . After this file is checked by our engineering team, we will issue an annual calibration certificate. This means that your dolphicam2 stays online, without ever needing to leave your facility. Find out more about the dolphicam2 here.
Yes, this can be achieved in two different ways. If individual voids are large enough, such as for needle voids, they can be resolved and measured directly using our geometrical measurement tools. In cases where micro pores may be too small to resolve explicitly, they can be detected via a reduction in the back wall signal amplitude. This effect can be quantified over a given area using our statistical measurement tools.
The dolphicam2 software offers a range of different display configurations, providing various combinations of A- B- and C-scans, as well as our 3D visualisation window. These layouts have been tailored to best suit the data being generated. Users can also manipulate the certain displays such as the gates, color palettes and measurement tools on the screen.
At the moment we do not. However, we take full advantage of the 128×128 matrix array in our current range of probes to provide a superior level of detail in real-time and in three dimensions. View the full range here.Can I customise the screen layout?
The dolphicam2 is IP66 rated, which means it can withstand powerful dust and water jets, however, it should not be fully submerged underwater. It is safe to immerse the front face of the TRM in few millimetres of water for a water-coupled inspection.
Scanning speed will depend on the specific equipment setup. With manual stitching or our Grid Tool, we can cover 30x30cm in around 10 minutes. With our Rapid Mapper, we can cover 1m2 in less than 4 minutes. Linear scanning speed with automatic scanners is typically 150mm/s.
Yes, our software enables stitching of individual C-scan images to enable mapping of large areas without the need for any peripherals.
The dolphicam2 transducer module (TRM) works using a crossing electrode principle. Across the face of the transducer, 128 transmitter electrodes cross with 128 receiver electrodes. Between the two electrode layers, a piezoelectric material is placed which converts electrical energy to mechanical (sound) energy.
To collect a pulse-echo-signal from a transducer element, a 70V pulse is excited on the transmitting electrode creating an ultrasonic pulse along the entire electrode. The ultrasonic pulse goes into the material and the reflected signal is sampled on one receiver electrode.
Each crossing point between the electrodes becomes an ultrasonic element, providing an aperture of 16,384 (128x128) elements (64x64 elements for our 1.5MHz TRMs).
Yes, we have a range of encoder options available for quick, C-scan mapping of large areas. These include are our Grid Tool – an indexed X-Y frame, and our Rapid Mapper – an encoded X-Y axis frame. We also have compatibility with a wide range of external scanners, from one axis line and string encoders, through two-axis pipe scanners, to robotic crawler systems.
The dolphicam2 platform provides straight beam inspection with unparalleled resolution.
We have multiple options depending on your inspection requirements, please contact email@example.com for further information.
We have achieved sub-millimetre detection in a range of materials. The material thickness and the ultrasonic frequency chosen will influence this resolution. The short wavelengths generated by higher frequencies provide superior resolution. This is how bats can use ultrasound to echolocate and catch insects, whereas we can’t do the same with our lower pitch voices!
The dolphicam2 can be used for to inspect a wide range of glass and carbon fibre reinforced composites as used in automotive, aerospace, defence, and energy markets. It can be also used to inspect metals in these sectors, as well as for adhesive bonding of similar and dissimilar materials. Plastics, multi materials and some ceramics can also be inspected.

The TRMs are highly ergonomic and easy to manipulate. With our softer delay line Aqualene and Aqualink models, this can conform to some curvatures. For fixed curvatures such as pipes, we offer a range of curved pipe shoes which match the outer diameter of the pipe.
Interchangeable delay lines are available on some TRM models.
