Ultrasound measuring instrument SL3000

Using ultrasound to find compressed air leaks and detect signs of wear at an early stage

Compressed air is one of the most expensive types of energy. However, 30 to 40 % of the consumption is often lost to leaks. Using the SL3000 you can detect such leaks in an extremely easy way, and thus immediately save energy with every leak that has been eliminated. Even pressurized gas lines can be quickly examined for leaks using ultrasound.

Moreover, the SL3000 effectively solves numerous tasks related to preventive maintenance. Without having to interrupt the ongoing operation, you can regularly test system parts and rotating machines for signs of wear using ultrasound, which allows you to detect potential damage at an early stage.

With the SL3000, measuring neither requires much time nor extensive training. By means of high-performance sound transducer technology and stereo headphones, ultrasonic signals are rendered audible and are at the same time displayed both numerically and indicatively.

The robust measuring device was specifically designed for continuous use in rough industrial surroundings while being compact enough to easily fit into every pocket. Depending on your needs, the SL3000 can be complemented with various airborne and structure-borne sound probes, which can be plugged onto the device in just one simple step.

The SL3000 is a compact ultrasonic testing device with a variety of accessories for professional location of compressed air and gas leaks as well as for an early detection of machine bearing damage:

  • Quick leak detection at compressed-air lines as well as steam, gas and vacuum systems
  • Wear control of rotating machines during operation
  • Tracing of electrical partial discharge at damaged insulation
  • Tightness testing in pressureless systems

Model calculation for leakage losses in compressed air systems

Large amounts of air permanently stream out at high speed even through the tiniest leaks in compressed air systems, resulting in considerably higher operating costs:

Leak dimensions Escaping air volume at 8 bar Energy loss**
[ø mm] [l/min] [l/annum]* [kWh/a]
1 75 39,420,000 5,125
2 260 136,656,000 17,765
3 600 315,360,000 40,997
4 1,100 578,160,000 75,161
* If operated 24 hours a day throughout the year.
** Owing to the additionally required motor power (0.13 kW per m³ of compressed air) for a higher volume flow to compensate the pressure loss.

A few practical benefits:

  • Equally compact and robust IP54 testing device for ultrasonic measurements
  • Simple detection of even the smallest leaks
  • Pinpoint leak detection with powerful sound transducer technology
  • Extremely soundproof stereo headphones allow for a safe detection even in noisy surroundings
  • Extensive range of plug-on airborne and structure-borne sound probes for various fields of application
  • Easy-to-read, backlit display with numeric and indicative display of measured values
  • Intuitive softkey handling with an additional maximum value display function
In addition to the ultrasound measuring instrument SL3000, the standard scope of delivery also includes an airborne sound probe, a directional sound probe with plug-on tip, an acoustic horn for a greater range, extremely soundproof stereo headphones with a connection cable as well as a transport case and operating manual.

The ultrasound measuring instrument SL3000 provides users with a wide range of applications including preventive maintenance and non-destructive material testing

Thanks to ultrasonic measurement technology, even non-experts are able to locate leaks in compressed air, gas and vacuum systems quickly and easily. If gas escapes from a leak, turbulences occur, which generate ultrasound. Without any aids, these ultrasound signals are not audible to the human ear. The SL3000, however, is able to convert these signals into information that the inspector can perceive both visually and acoustically.

In addition to the quick and reliable detection of compressed air and gas leaks, the handy ultrasonic testing device SL3000 is also suited for tightness tests in various system, for wear control of rotating machines and for tracing of electrical partial discharge at damaged insulation. Checking of steam traps and valves is also part of the mobile device's range of tasks.

Manifold airborne sound probes for detecting compressed air and gas leaks

The airborne sound probe (1) included in the scope of delivery of the SL3000 is perfectly suited for leak detection. Simply plug it onto the SL3000 and start detecting leaks over distances of up to 3 metres.

In order to roughly define the location of the leak as a first step, an additionally acoustic horn (2) is also supplied.

This airborne sound probe attachment increases the measuring range and allows for leak detection from a distance of up to 8 metres.

Afterwards, the leak can be precisely determined using the shotgun with tip (3), which is also contained in the scope of delivery of the SL3000.

The shotgun can be attached to the airborne sound probe and thus shields lateral ultrasound sources and indicates the leak with pinpoint accuracy.

Poorly accessible locations can be checked using the optionally available gooseneck probe, whose flexible neck allows you to position the probe tip on concealed pipelines.

For leak detection over larger distances of up to 20 metres, the SL3000 can moreover be equipped with an optionally available parabolic probe.

Due to its wide range and an integrated red dot sight, this probe can be used to safely and precisely detect compressed air leaks even over large distances.

Thanks to the parabolic probe's high sensor sensitivity and very good directional effect, electrical partial discharge and insulation damage can also be traced, e.g. at medium voltage installations.

Structure-borne sound probes for machine diagnosis and fitting testing

Long and short structure-borne sound probe

The long structure-borne sound probe with stainless steel tip (4) available as an accessory can be directly placed on the test object and enables fast inspections in order to prevent damage on rotating machine components without disturbing the ongoing operation.

If testing is performed regularly, changes in sounds can give valuable hints as to signs of wear in ball, roller or slide bearings, for instance. It is also possible to check centrifugal pumps for cavitation, and steam traps for continuity and functioning.

In addition, the short structure-borne sound probe (5), which serves as an electronic stethoscope, is particularly well suited for inspecting fittings, gate and globe valves.

Tightness tests with ultrasonic transmitters

Using the ultrasound measuring instrument SL3000, you can also check windows, doors and other parts of a building for tightness in a quick and easy way. An ultrasonic transmitter is positioned inside the closed room. Then, the outdoor area is inspected using an airborne sound probe. The ultrasound generated by the transmitter escapes at leaky spots and can be detected by the SL3000.

This method can also be used for inexpensive tightness testing in other pressureless systems such as cabins, heating cabinets, air conditioning units or tanks. Apart from the ultrasound measuring instrument SL3000, all you need is an additional ultrasonic transmitter such as Trotec's SL800T.
