In simple terms, ultrasonic leak testing can be compared to the familiar “bicycle tyre” method: If a bicycle tyre has a puncture, fill it with air and submerge it in water to find the leak by looking for bubbles rising to the surface; then it can be sealed. Of course, ultrasonic leak testing is a highly sophisticated industrial technology that only uses this approach for illustrative purposes. In practice, components such as tanks, pipes and housings are tested for leaks in series production in a fully automated and precise manner – millions of times over, for example in the automotive industry or building engineering.
Ultrasonic leak testing
Ultrasonic leak testing enables precise, reliable detection of gas bubbles in a water basin. This operator-independent, automated process minimises human error and increases efficiency even with low leak rates.
This visualization shows the USBD4000 in use. The test specimen is completely immersed in the water bath so that even the smallest leaks can be detected. Gas bubbles escape from the leak and rise in the water. When these bubbles pass through the sound field of the USBD4000, they are detected by the ultrasonic system. In this way, the leak can be reliably detected and precisely located.
USBD4000
What does that mean? 25 years of experience in ultrasonic leak testing in compact, next-generation hardware and software:
Next-generation hardware that is easy to install and compatible with all SPLTA systems
Preventive maintenance with real-time, long-term data
Improved signal processing and interference suppression
Precise leak detection and real-time measurement results
Efficient error handling and user management
Flexible system – precise results
The USBD4000 offers a reliable solution for a wide range of requirements. While the basic design and scope of delivery remain consistent, the number of ultrasonic sensors varies. This determines the size of the sound and test field, and therefore the maximum size and number of workpieces that can be inspected. This allows us to optimally tailor the inspection to your individual needs – for maximum precision and efficiency.

Automation instead of manual inspection
Our ultrasonic leak testing automates the entire process and monitors every point of the test piece throughout the entire measuring time. This eliminates time-consuming manual checks and ensures that potential leaks are not overlooked.
Precise leak detection
Compared to the helium sniffer solution, where each position is only briefly scanned and slight air turbulence can delay the detection of leaks, our ultrasonic measurement permanently checks every relevant measuring point with a guaranteed leak rate. This allows even the smallest leaks to be reliably located, significantly improving quality assurance.
Savings through efficiency
Continuous monitoring of all measuring points significantly reduces testing times. At the same time, maintenance and operating costs are reduced compared to more complex helium sniffer solutions. This optimises resource utilisation and increases the cost-effectiveness of series production.
Active sensor unit
The active sensor unit consists of a sensor holder with up to 29 ultrasonic sensors, screened-off sensor cables, active sensor electronics (with measuring electronics) and a protective hood.
Control computer with Windows 10 or Windows 11 IOT
The control PC is used for higher-level measurement sequence control and enables the customer to operate the system intuitively. We also carry out the entire parameterisation via the control PC. Remotely as well, if required.
Active sensor electronics

The sensor unit for ultrasonic leak testing can be easily integrated into existing production lines and enables automated inline quality assurance. The precise detection and localisation of leaks during the production process ensures seamless control without interrupting the workflow.
SPLTA ultrasonic leak testing offers versatile applications in various industries, from automotive to energy. Whether for filler pipes, fuel tanks, hot water storage tanks, or battery packs – this innovative testing method ensures the highest quality and safety through precise leak detection and localization for a wide range of products and industries.
hot water storage tank
Not only the automotive industry places special demands on the quality of its products, but other sectors also manufacture products that require high levels of leak tightness. Examples include leak testing of hot water storage tanks in the heating, building, water management, and energy sectors.
Compressors and compressors
Unique: Fast and reliable leak testing and leak detection using ultrasonic gas bubble detection in a water bath. Integration of strength and pressure testing as an additional quality assurance feature.
fuel tank
Due to the stringent requirements for hydrocarbon emissions from fuel tanks, ultrasonic leak testing plays a central role in fuel tank quality control. Specifications are becoming increasingly stringent. Furthermore, the optional ultrasonic gas bubble detection allows not only the detection but also the localization of leaks.
Filler pipes
In the automotive sector, not only fuel tanks but also filler necks need to be tested for leaks. This can easily be done using ultrasound, even with a combined fuel tank and filler neck. Ultrasonic leak testing is a proven and reliable quality control method.
