Superior Accutrak VPX-WR Ultrasonic Leak Detector
The Superior AccuTrack VPX-WR is an Ultrasonic Leak Detector with state-of-the-art technology for large institutions and other industrial environments such as schools, hospitals, factories for ultrasonic gas leak detection. The AccuTrak VPX-WR is an ultra-durable and waterproof ultrasonic leak detector that incorporates Superior’s patented and trademarked circuitry called “DND” (Dynamic Noise Discrimination). This advanced technology allows the ultrasonic leak detector to detect and translate a broad range of ultrasound (20kHz to 100kHz) without the guesswork found with manual tuning. The AccuTrak VPX-WR is absolutely the best leak detector on the market for finding leaks fast, especially in loud plant environments as well as for a variety of plant maintenance applications.

The advanced DND technology constantly scans the complete range of ultrasound from 20 to 100kHz and automatically tracks both the frequency and intensity of incoming signals. When a sound is detected which is above the previous intensity baseline, it uses a sophisticated mapping process rather than simple subtraction to translate the sound to the audible range. The result is a leak detector able to find leaks faster than any other with no tuning.
The Accutrak VPX-WR ultrasonic leak detector is a cylindrical instrument with the sensor located in the sensor horn at one end of the instrument and the control and multifunction connector at the other. It is covered with a rubber grip to prevent the slippage of the instrument when the user has greasy hands. The operation of the VPX-WR is very simple and with the Automatic Frequency Tuning (DND) it makes it possible to detect and interpret a broad range of ultrasound while utilizing only one control. In addition to DND, a narrow frequency band of ultrasound is translated using heterodyning, and functions just below the set point of the DND. The DND frees the user from having to tune the instrument for different frequencies, and it provides a distinctly different sound especially when searching for vacuum leaks.
Air or Gas Leaks
Pressurized air leaks (gas) generate high-intensity ultrasound. In places where no other noise is present, sonic or ultrasonic, finding the exact location of a leak is relatively easy. This is because ultrasound is like a microwave and microwaves propagate in straight lines. In loud industrial environments such as a mechanical room for a compressor, a leak might appear to originate from many spots. The sound reflects off walls, the ceiling, and many other surfaces. However, none of these reflections are as strong as the true source of the sound, the leak. The DND incorporated into the ultrasonic detector makes it extremely easy to locate these strong signals while eliminating the weaker ones.
Searching for vacuum leaks is fundamentally the same as with air leaks, with one difference: the sound generated at the leak is stronger toward the inside of the system that generates. Fortunately, the sound remaining on the outside is strong enough to create a signal that can be picked up in some cases, several feet from the leak. The VPX-WR helps you find the location of the leak, and by reproducing the sound fluctuations, it gives you an indication of its rate. Vacuum leaks sound the same as air leaks.
The VPX-WR can also be used with the touch probe to locate internal leaks.
If a leak is within a device, like a steam trap or a valve, the VPX-WR using the touch probe attachment will indicate the leak by detecting the sound it generates. Using the touchprobe, you only need to apply just enough pressure to make a good contact with the pipe or valve. The sound of a leaky trap or valve will be the strongest at the point of the leak and it will be like a whistle that constantly blows.
Internal leaks in a hydraulic system can be challenging to find. The ultrasonic sound detector can be used to listen to the sound of the fluid internally to indicate the location of the fault. Generally, when checking for an internal leak in a cylinder, the side that is leaking can be easily found. Valves of all kinds, even steam or water, can be checked without guessing about their condition.
The most common mechanical failure is a broken or seized bearing. However, this type of failure does not happen instantly under normal conditions. When bearings begin to fail, their sound changes. This sound can be detected with the VPX-WR ultrasonic leak detector HVAC by touching the bearing house with the touchprobe and listening for abnormal sounds. By having periodic maintenance, you can prevent major disasters in your machinery which could possibly cause downtime. Periodic maintenance using the ultrasonic leak detector’s touchprobe would also allow for a technician to learn the sound patterns of the bearings to know when it was failing.
When readings are inconsistently high for a particular test point, chances are there is a problem deserving attention. Ultrasonic instruments can help you gauge the extent of this wear and warn customers before it’s too late. A chart can be used to show the customer hard data. You can use a spreadsheet such as Microsoft Excel to record the readings and create graphs and charts to clearly illustrate these problems. The ability to provide this information can be incredibly valuable to your customers.
The VPX-WR detects ultrasound and does NOT detect the presence of a specific gas. It is not a gas “sniffer”. Therefore, the ultrasonic leak detector can function in areas where heavy wind or a concentration of fumes render other detectors useless.
The Accutrakultrasound leak detector uses the only sensor in the world that combines high sensitivity and is hermetically sealed. Its resistance to water, steam, oils, fumes, dust, etc. allows the instrument to be used in hostile environments where other detectors fail. The ultrasonic sound detector’s controls, indicators, and plugs are totally sealed, making the unit 100% watertight. The internal circuitry is housed in hard-anodized aluminum for durability and longevity. The aluminum housing is surrounded with a padded grip for comfort and easy handling. The Superior Signal VPX-WR is the most durable ultrasonic leak detector of its kind.
The included headset is the best of its class and used exclusively by military and commercial aviation. The headset provides sound attenuation when wearing a hard hat, muffling loud machinery noise, which can be hazardous to hearing.
