WA-EUS-720

ULTRASONIC LEAK DETECTOR

The Ultimate Tool for Leak Detection in Compressed Air & Inert Gases.

When leaks develop as a result of failed seals or internal components, they emit an ultrasonic sound wave that is above the natural range of human hearing. The WA-EUS-720 Series Ultrasonic Leak Detectors convert this ultrasonic sound by an electronic process called ‘heterodyning’ that accurately converts the ultrasounds sensed by the instrument into the range where users can hear the audible signal through a headphone. The high frequency, short wave characteristic of ultrasound enables users to accurately pinpoint the location of a leak or a particular sound in a machine.
WA-EUS- 720 ultrasonic leak detectors allow maintenance personnel to confirm a diagnosis on the spot by being able to clearly discriminate among various equipment sounds. The basic advantages of WA-EUS-720 ultrasonic leak detectors are that they can easily locate leaks, provide advanced warning of impending mechanical failure and can be used in loud, noisy environments.

The large LCD display bar graph displays the leaking intensity and converts the ultrasound frequencies to human audible range. When working in unpressurised systems, or if the pressure is not sufficient enough to detect or verify a leak with the Receiver alone, use the Transmitter to generate the ultrasonic signal (included with the WA-EUS-730 Kit). In extremely noisy environments where there is strong ultrasonic noise generated by running machinery or equipment, the Receiver’s filter function can filter out up to three main noise frequencies which would otherwise hide the noise of the leak.

Features :

• 2.5”LCD display with bar graph
• 20 kHz to 90 kHz frequency range: optimal range for detecting a variety of leakage events
• Three filters to remove main noise frequencies in noisy environments
• Adjustable Receiver sensitivity and Three Transmitter signal strengths for accurate leak pinpointing
• Quality Noise Cancellation headphones (Optional) to help identify the source of the leak
• Parabolic Dish to direct the ultrasound towards the sensor
• Detachable Tubular Extension provides additional reach in hard to reach areas

Find Leaks Even in Noisy Environments :

In some situations, there might be strong ultrasonic noise generated by running machinery, motion sensors or other equipment. This noise will cause the Receiver to read the maximum signal strength of this noise interference on the display regardless of the sensitivity settings and make it unusable for detecting leaks. The Filter function was designed for these situations. Simply press the Filter button and the Receiver will automatically detect and filter out up to three main noise frequencies.

Visual and Audible Leak Pinpointing :

While scanning a target area with the Receiver’s ultrasonic microphone the displayed bar graph will indicate proximity to the source of the leak. Plug the headphones into the Receiver to audibly hear the leak and verify its source. For example, air leaks will produce more of a hissing sound while electric discharge manifests in a ticking sound.
