SDT270: The power of ultrasound for maintenance professionals.

The ultrasonic leak detector SDT270 features multiple significant innovations dedicated to leak detection (compressed air, vacuum, steam,...) and to the improvement of predictive maintenance programmes. Manufactured by and for maintenance professionals, the SDT270’s innovation show our commitment to the production of intelligent and progressive instruments. Not only is the SDT270 the first portable ultrasound detection device to include both a built-in temperature sensor and a laser tachometer, but it’s also the first one to feature an onboard SQL database to capture and manage survey data.


SDT270 main features:

  • Measures broadband ultrasound signals with a 100kHz bandwidth
  • Realizes data acquisition with a 250kHz sampling frequency
  • Uses long-duration time sampling and data streaming
  • Integrates built-in thermometer and tachometer with a laser
  • Includes a SQL database.
  • Includes an operator logging in.
  • Insures full measurement traceability from operator to sensor.
  • Warns the operator when an alarm is triggered
  • Is IP (Internet) addressable
  • Is remotely controlled and operated
  • Incorporate 2 measurement channels.


No matter what your application is … WE HEAR MORE.

Accurate and comparable wave files.

The SDT270 is the first ultrasound detection device to use “high fidelity” ultrasound recording to allow inspectors to maintain a database of accurate sound files. Each time signal is sampled 250.000 times per second and stored into the SDT270’s substantial internal memory. The results are clear and easy to compare signals, allowing the establishment of a reliable and precise diagnosis.


Two channel inputs.

The availability of 2 channel inputs allows you to connect several sensors simultaneously and to carry out consecutive measurements. Without having to change or reconnect sensors, static data (ultrasound data in dBµV, temperatures, rotations per minute and accelerations) as well as dynamic data (time signals recorded into .wav files) can be stored sequentially. The SDT270 redefines the concept of intelligent instrument design to make even more efficient use of your time.



SDT270’s upgradeable platforms.

The SDT270’s platform offers many upgrade possibilities. The upgrade is done by remote control, giving you access to new or more advanced functionalities. There’s a choice between six basic configurations to which you can add multiple sensors to create a detector/collector matching your needs. Add the UAS suite software to it and you’ll obtain a synergistic partnership between your SDT270, your maintenance team and your computer.


UAS – Ultranalysis® Suite.*

UAS manages the collection, processing, and analysis of the data measured by the SDT270. It’s a library in which you can store and organise collected data in order to make it easy to find. UAS can process static data (dBµV, °C/F, RPM, SCFM) as well as dynamic data (ultrasound signals for time and spectrum analysis). The UAS tree structure allows any size of database and gives the possibility to divide it into multiple survey rounds for easier management. Furthermore, synchronised databases in both your SDT270 and your computer allow on-the-fly creation of survey points.


ATEX certified version

The SDT270 now meets the requirements set by ATEX Directive 94/9/EC (II 1 G Ex ia IIC T3/T2 Ga) for use in the most dangerous and potentially explosive atmospheres in the world. For the first time ever ultrasound inspectors working in intrinsically safe rated zones now have access to the unique and advanced features of the SDT270.

It offers new possibilities for petro chemical plants, offshore drilling rigs, and refineries, not to mention the many other areas where ultrasound could not be used.

While it took more than a full year to complete the certification, the official rating for the SDT270 and accessories (headphones, RS1 contact probes and flexible sensor) is one of the highest attainable.


Remote support and trainings.

The SDT270 is the first ultrasound detection device accessible through its IP address. Remote access will bring new possibilities to your maintenance programme in terms of support, trainings and measurement triggering.

Your compressed air leak program is complete with the SDT270 Leak Surveyor Kit.


Finding compressed air leaks in a high noise environment is best done with an ultrasound detector. The SDT270 Leak Surveyor Kit is configured to make the job safe, easy, and fun.

When selecting the accessories for this kit our focus was on safety and comfort first. The leak surveyor kit is equipped with sensors to ensure all leaks are found and tagged without compromising operator safety.

The SDT270 comes equipped with an internal airborne sensor, great for finding easy to reach leaks common to most compressed air systems. This default sensor powers up automatically when the instrument is switched on.


Internal ultrasound sensor

The use of the Internal US Sensor is recommended only when a direct and easy access to the equipment to be controlled is possible. For this configuration, its sensitivity is sufficient.

The use of the precision rubber, when mounted on the ultrasound sensor, reduces the effect of competing ultrasound sources.


Flexible sensor

The sensitivity of the flexible sensor is similar to the sensitivity of the internal ultrasonic sensor. Consequently, its use is also recommended when elements to be controlled are directly accessible. On the other hand, its ergonomics makes easy to check elements difficult to reach or control high densities of pneumatic equipment. The flexible sensor is then the most powerful sensor when facing these kinds of configuration.

Consequently, the flexible sensor should be used in complement of the extended distance sensor to pinpoint the leak spot.


Extended distance horn

The extended distance horn is remarkable for its sensitivity: it is 20 times more sensitive than both the internal ultrasonic sensor and the flexible sensor. 20 more times represent a gain of 26 dBµV. Consequently, the extended distance horn should be used in priority and especially when leaks are going to be quite small (i.e. vacuum leak) or if you might be up to 5 meters away from the leak.

However its use could be delicate for the zones with a difficult access. In the same way, the precise localization of the defective element could be arduous when controlling high density of pneumatic equipment.


Parabolic sensor

When the zones to be controlled are more than 5 meters away, the parabola is the best suited sensor. To the contrary, its use is not recommended for short distance detection.

Its sensitivity is better than the extended distance horn for long range, but especially its laser makes it possible to remotely locate the defective element precisely.



SDT270 Leak Surveyor Kits combine building blocks that aid ultrasound inspectors with compressed air leak management programs. These kits provide safety and ergonomics while enhancing detection in difficult areas.


Basic kit

The SDT Leak Surveyor Basic enhances leak detection by including sensors that extend the versatility of the SDT270SB (Static/Basic). This kit is designed for speedy surveys that are mindful of your safety and comfort. Included in the kit:

  • SDT270SB (Static measurements)
  • Flexible sensor
  • Extended distance horn.


Pro kit

The SDT Leak Surveyor Pro features the SDT270SD (Static/Datadump) receiver with built-in internal airborne ultrasound sensor. The 270SD has a 20 node memory and transfers stored measurements as XML report. In addition to the Leak Surveyor Basic is included the parabolic sensor with laser pointer. Use this sensor for inspecting leaks in ceiling pipes where pinpoint laser accuracy is required. Included in the kit:

  • SDT270SD (Static measurements + Datadump software)
  • Flexible sensor
  • Extended distance horn
  • Parabolic sensor with laser pointer.



Intermediate version

Intermediate version or useful option before Leak Detection Pro Kit: the SDT270SS (Static/ Storage). The 270SS platform features a generic onboard memory for storing data captured with any ultrasonic sensor. The structure of the memory is a 20 node fixed tree named node 1 through node 20. Data can be viewed on the LCD of the SDT270SS.
