SeCorr® 08 Correlator
A Leak Noise Correlator (LNC) with the latest DSP-techniques for the calculated detection of water leakage.
Key Benefits
- Digital Signal Processor (DSP) – Fast accurate calculations allowing quicker leak location
- Direct microphone and headphone sockets – Allows SeCorr® 08 to be used as a basic electro-acoustic leak detector
- High resolution pixel display – High definition of display
- All system components contained in one robust case – All parts can be recharged whilst remaining in the case
- Lightweight ergonomic design – Comfortable to use over a full working day
- Application specific menu structure – Intuitive operator sequences
- Fast Fourier Transformation (FFT) correlation – precise location even with the most challenging leaks
- Radio transmission of over 6667 ft (2,000 m) – Correlation possible over long distances
- Wide selection of components available – Select optimal configuration for the prevailing conditions
- Two levels of software, standard and professional – Chose the version most suited to your requirements.
- Input via jog dial and / or water resistant film pad – Users can select best or both methods according to their personal preference e.g. with gloves on or off
- “Coherence analysis” – Allows automatic or direct settings of frequency filters for optimal performance and easier location of the most difficult leaks noises

Transmitter
As soon as the microphones receive the noise from a leak the signal is automatically amplified to the optimum level and transmitted digitally along with the amplification details to the SeCorr® 08.
Both pieces of information are analyzed and processed by the SeCorr® 08. Utilizing 500mW transmitters signal transmission is clear and strong. Correlation of up to 4km is possible; local conditions may affect the range. Even if the radio transmitter is located within buildings or behind cars or trees correlation can be carried out successfully.
Since correlation requires two microphones, these can either be connected to both radio transmitters or if using only one radio channel, directly to the SeCorr® 08.

Sensors

Highly sensitive Piezo accelerometers record noises in the frequency ranges of approx. 1 to 10,000 Hz. A range of adapters enables connection to a wide variety of measuring points.
Hydrophones do not pick up the sound from the pipe material, but directly out of the water column. This offers a considerable improvement of the location range, especially with correlations on plastic pipes. Locating leaks over several hundred meters is possible.
Software
- Software "Professional" for all location demands
- Software "Standard" for the less experienced operators
Case
This robust plastic case offers space for all system components. The Receiver and two transmitters can be charged simultaneously inside the closed case.
