Overview and application description of the different sensor types

Acoustic trumpet (standard tool)	Straightening tube
The acoustic trumpet bundles incident ultrasonic waves, thereby extending the range of the device. This behaviour makes it ideal for medium distances. The leakage can be heard from large distances, for precise detection, the user must approach the leakage and consistently follow the "loudest" point. Individual compressed air components are then checked for precise detection. Quantification distance (distance) □ 1 – 6 m Use of acoustic trumpet: Average distance to pipe/component 0.2 - 6 m Low interfering noise Leakage freely accessible Use at distances of up to 6 metres if no parabolic mirror available	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. Quantification distance: 0…0,2 m Use of focus tube: Short distance to pipe/component 0.05 m Pipe/component freely accessible Pipes and components to be inspected are very close together Medium to high noise Use when no gooseneck available
Gooseneck	Parabolic mirror
The gooseneck should be used if the pipes and components to be inspected are physically very close. In addition, the shape of the gooseneck can be flexibly adapted to easily inspect hard-to-reach pipes and components. The sensitivity of the gooseneck has been reduced to dampen noise. This makes it ideal for target-ed, local testing of compressed air components at high noise levels, for example in systems using pneumatic cylinders and in compressed air distribution cabinets Quantification distance à 0 …0.05m Use of gooseneck: Short distance to pipe/component 0.05 m Leakage not freely accessible Medium to high ultrasonic noise Pipes and components to be inspected are very close together	The parabolic mirror bundles horizontally incident ultrasound in its focal point where the ultrasonic transducer is located. On the one hand, this leads to a considerable amplification of the measured ultrasound (high range) and, on the other hand, to a very precise directional behaviour, since ultra-sound that does not incident horizontally is reflected by the reflector. The combination of these two characteristics enables the parabolic mirror to precisely locate leaks at large distances. Quantification distance à 3 – 12 m Use of parabolic mirror: Large distance to pipe/components 3 – 15 m Interfering noise Leakage not freely accessible (behind a fence) Near leaks (superimposition))

Device components and controls

Assembly with acoustic trumpet

The acoustic trumpet allows acoustic amplification by bundling the sound waves and specifies the location of the leak. Due to the special construction of the integrated laser pointer is still usable. The camera is integrated on the bottom of the acoustic trumpet and is electrically connected to the preamplifier module via the jack plug.

Assembling is done by plugging the individual components until easy locking audible (plug in to the stop).

The components are removed in the reverse order; for unlocking the preamplifier module, the release button must also be pressed.

Assembly with focus tube with focus tip

The focus tube with focus tip is used to detect very small leaks, to accurately locate them.

Just like the acoustic trumpet, the tube can be plugged into the preamplifier with ultrasonic receiver.

The use of the camera is no longer possible.

The components are removed in the reverse order; for unlocking the preamplifier module, the release button must also be pressed.

Assembly with Gosseneck

Due to its flexibility, the gooseneck tool is used for punctual measurements in hard-to-reach areas. Connection to the LD 500 is via the supplied spiral cable, see Figure 10.

It is no longer possible to use the camera.

To remove the component, remove the connection cable by pressing the release button on both sides and pulling off the cable.

Assembly with Parabolic mirror

The parabolic mirror is used for measurements at greater distances as well as for high requirements regarding selectivity and location of leakage positions.

Connection to the LD 500 is via the supplied spiral cable, see Figure 11.

To remove the component, remove the connection cable by pressing the release button on both sides and pulling off the cable.

Note: To use the parabolic mirror and gooseneck, these components must be activated in the LD 500 during initial commissioning in order to save the component-specific adjustment parameters. If this has not already been done ex-works, the data for this is supplied via USB stick. For the activation (parameter import), see chapter 11 Operation here in Sub chapter "Export / Import".“.

Start-up / / Application LD 500

	Please first observe the safety instructions in Chapter 2

Switch on

Hold down the power button for about 1 second, the power will turn on, and a start-up sequence will appear on the display. Pressing the button again switches the device off again.

On-Off button, see device components and controls

Headphone Volume Up / Volume Down

The volume up and volume down buttons in the headset can be increased or decreased in 16 steps.

Continuously pressing the button automatically increases / decreases the value.

Volume up / down buttons for headphone volume, see device components and controls

Please make sure the headphone level is <50% before putting on the headphones.

Sensitivity level

Ultrasound levels can be understood as a "loudness" of the leakage.

With the “Sensitivity" button, the sensitivity of the LD500 can be adjusted to the environment, which strongly influences the acoustic behaviour of the device and increases or decreases the valid value range. A reduction in sensitivity reduces the range of the leakage reading but the "responding area", indicated by the circle in the display, also gets smaller, which considerably simplifies detection.

Sensitivity levels

0 – 60 dB = Highest sensitivity level of the device (use with small leaks and no noise), selection with the "HiSn" button or the "Sensitivity" button

10 – 70 dB = Leakages and noises get "less noisy", the range is reduced.

20 – 80 dB = Leakages and noises get "less noisy", the range is reduced.

30 – 90 dB = Leakages and noises get "less noisy", the range is reduced.

40 – 100 dB = Most insensitive stage (large leaks, many noises à for heavy-duty application)

By default, the LD500 is set to the auto function and will automatically switch between levels (10 – 70 dB to 40 – 100 dB).

Laser On/Off

The laser pointer can only be switched on or off via the laser on / off button  in the display (not via the membrane keypad). When switched on, the display shows a laser warning symbol.

With the help of the Backlight dimming after button, after a definable time interval (here after 15 minutes), the Backlight can be reduced to the minimum.

As soon as the dimmed screen is operated again, the Backlight is committed automatically on the last set value before dimming.

15

To reduce the energy consumption (device runtime), you can switch off the display backlight by setting "Backlight off after".

Remark:

At the first touch, the Backlight in our example is reset to 39%, after that a "normal" function	operation is possible.

Important:

If the Backlight dimming after button is not activated, then the Backlight stays permanently on, in the currently set brightness.
