Immersion Tanks

Advanced UT Systems

General Information

Complete range of reliable and high performance ultrasonic immersion tanks. They can be used as automatic inspection systems for ultrasonic (UT) immersion scanning, through transmission with squirter/gantry or Air Scan systems.

Tecnitest NDT Ultrasonic Immersion Tanks can be used for industrial Non Destructive Testing (NDT) applications, research projects and training.

The modular design of the ultrasonic immersion tank systems allows upgrading, easily matching dimensional, kinematic and technique related specifications.

The software of the system, VisualScan, allows for user test parameter set up, scan programming and result evaluation.

  • Electronic controller-based commercial industrial PLC commanded by an independent computer. This architecture enables updating the computer operating system and programs easily and ensures that the movement of equipment is made more reliable and secure.
  • Encoders in X and Y axes for acquisition synchronization (also θ when an external axis is available).
  • Desktop PC (optionally, in industrial rack).
  • Low noise electronics for ultrasonic acquisition including a socket box on the system bridge frame.
  • Control switches, safety system and emergency stop button.
  • Control of movement made by commercial equipment to facilitate maintenance.
  • Index adjustable from 0.1mm (depending on model)
  • Programmable speed to 500 mm / s.
  • Possibility of inspection in various planes.
VisualScan is a dedicated application software for automatic ultrasonic inspection systems under MS Windows 10, easy to operate and intuitive… at the same time complying with requirements of common application standards (Airbus, for inspection of composite materials).

Key Benefits:

  • Software of system based on Windows.
  • Software up-datable by via Internet.
  • Friendly interface easy to use.
  • Fast programmability for self-learning.
  • A-SCAN and C-SCAN in real time on screen.
  • Programmable Speed and Index
  • Creation of bitmap files.
  • Complete file of inspection data.
  • Sending of results through Internet.
  • Evaluation in real time by local network

It’s optimized design and suitable integration with the system mechanics and electronics, it can control the system and the inspection with the best performance regarding scanning speeds, setup options and quality of the results.

The systems that we manufacture are generally the same design, but each customer has their own specific needs.  As such we try to accommodate our customers and therefore, we incorporate the best ultrasonic equipment to suit the customers’ needs.  Doing this we ensure that the customer receives the latest technology available.
Sonatest DFDs can also be used with this equipment.  The customer may also specify a DFD or indeed any Phased Array Equipment that he wishes to use providing that there are digital outputs to enable us to generate a C-Scan and the relevant data to be able to produce A-Scans and B-Scans.

Depending on the choice, particular capabilities and features of the system shall be defined in terms of dynamic range, number of channels, available real time presentations in high speed tests, etc.
