    CS Instruments GmbH & Co. KG for disposal. CS Instruments GmbH & Co. KG offers no guarantee in relation to the suitability for any other purpose and accepts no liability for any printing errors in this operation manual. The same applies to conse- quential damage in connection with the delivery, capacity or use of this device.

  • Page 3: Intended Use

    2. Intended use The LD 500 is a leak detector for quick and reliable leak detection in/on compressed air systems. The LD500 leak detector evaluates the ultrasonic waves generated by the leakage based on distance and pressure. It is solely designed and constructed for the intended use described here and may only be used for this purpose.

    6. Leakage detection This chapter describes the best use of the device in practice. Leakage detection procedure The following procedure should be performed in the company on a periodic basis to consistently keep the leakage rate to a minimum. The aim should be a sustainable leakage rate of 5 to 10 % as one-time detection and elimination does not permanently reduce the leakage rate and new leakages will occur again afterwards.

  • Page 10 6.4.2 Straightening tube The straightening tube permits only very few ultrasonic waves to pass in the direction of the ultrasonic transducer, allowing leakages to be located very precisely. For this reason, the use of the straightening tube is recommended for small distances, for the precise detection of the corresponding leakage.
  • Page 11 6.4.4 Parabolic mirror Before the parabolic mirror can be used, its data – located on the supplied USB stick – must be imported into the LD500, if it was reor- dered. Import: Export/Import → New tool → Parabol_xxxxxxxx The parabolic mirror bundles horizontally incident ultrasound in its focal point where the ultrasonic transducer is located.
  • Page 12 The highest sensitivity level 0 – 60 dB of the unit can be set using the "HiSn" button or by manually changing the sensitivity level using the "Sensitivity" button. This mode should be used for the detection of small leaks in a quiet environment. 6.5.1 Sensitivity level button 0 –...
  • Page 13 Production and manufacturing processes may give rise to ultrasound noises at times. If, for example, a pneumatic system blows off air at regular intervals, the LD 500 picks up on this. If leakage detection is severely impeded by these interfering noises, it is recommended to perform leakage detection according to Option 1 or Option 2, if the pipes are pressurised but the manufacturing processes have been stopped.
  • Page 14 Superimposition of leaks: If leaks are close to one another, the emitted ultrasound overlaps. In this case, it is recommended to seal the leak- ages using a cloth. This enormously increases the accuracy of the measurement, especially for the quantification of the leakage. At the same time, measurements should be taken in close proximity to the components.
  • Page 15 Documenting the leakage If the leakage has been found, the pressure and distance to the leakage adjusted and the leakage de- scribed, it can be "captured" with the "Save" button. Afterwards it is possible to check the parameters (pres- sure and distance) and to precisely define the measure- ment place with company, building and location.
  • Page 16 All relevant data of the leakage are shown in the image and a final check can be done again before saving. All leakages, including entries made, are saved to the journal file. Exporting journal data Once all leakages have been documented, the data must then be exported to a USB stick.
