Custom UMS test tanks
Our ultrasound test tank systems are custom built to suit the end user’s requirements and additional features can be included.
Overview
Precision Acoustics ultrasound test tank systems are custom built to suit the end user’s requirements and additional features can be included. These links offer more details on UMS software and acoustic parameters, with these UMS downloads also available.
Customisation options
| Motorised axes | Standard systems have 3 motorised axes but we have made systems with 10 motorised axes. The axes are fitted with linear encoders to ensure repeatable positioning. Limit switches are fitted to all axes. |
| Scan step size / resolution | Linear encoders give positional accuracy and linear repeatability ± 0.005 mm over length of travel and system resolution 0.001 mm working speed 20 mm per second and fitted with user adjustable limit switch and emergency stop control. |
| System geometry | UMS can be configured either “horizontally” or as a “shoot down” system for open back transducer testing. |
| Frequency range / maximum tank size | Frequency range: this will depend on the physical size of the test tank and acoustic lining. Please contact us for accurate information on tank size requirements for your working frequency. Standard tanks are 1 m x 0.5 m x 0.5 m which are suitable for measurements in the range 0.5 MHz to 60 MHz. We have supplied tanks up to 3 m x 1.5 m x 1.5 m which are suitable for measurements above 50 kHz. Depending on the physical size of the water tank it can be bench mounted or positioned at a reasonable working height. |
The supplied software integrates the stepper motor driven positioning system, oscilloscope and PC. It can be customised for individual clients but as supplied it allows the user to conduct linear and planar scans, store the digitised waveform and computates all the relevant acoustic parameters. Report generation and scripting enables output reports to be generated for any application.
| Programming language | All software is written in LabVIEW 2021 and later. |
| Automates planar scanning routines | The software integrates the positioning system, oscilloscope and PC for automated data capture and storage. |
| Data processing | The included post processing software enables the calculation of standard acoustic reporting parameters from the acquired data. |
| Customised software | We can customise the software for customer specific applications and equipment. The software integrates with Keysight Technologies oscilloscopes (DSO-X 3000 Series) but we can change the software to suit other oscilloscopes when required. |
Optional Extras
- PA membrane or needle hydrophones
- Hydrophone mount for hydrophones from other manufacturers.
- Alternative transducer mounts.

Ultrasound measurements rely on the ability to measure accurately the acoustic field. The UMS4 system has three motorised axes (x,y,z) each capable of a 6-micron repeatability. The system supplied complete with an electronic control module and a PC with preloaded UMS software. The software is optimised for interaction with Keysight Technologies DSO-X 3000 series oscilloscopes but the works with many other modern oscilloscopes.
Options include an additional “rotational axes positioning device” to facilitate accurate alignment of the transducer’s acoustic axis with the hydrophone; water conditioning system; hydrophone and transducer mounts.
To simplify purchasing for our clients we can also supply all power amplifiers and function generators.
