Superior Accutrak VPE-2000 Digital Ultrasonic Leak Detector for Industrial Maintenance

Part Number: VPE-2000
0 Review(s)
The Superior Accutrak VPE-2000 is a digitally controlled ultrasonic leak detector that is used for detecting the high-frequency sound associated with friction, arcing, and turbulence in industrial systems. The VPE-2000 Ultrasonic Leak Detector can be used in large institutions or other industrial environments as well as schools, hospitals, hotels, and factories for a variety of leak detection and plant maintenance applications. The Accutrak ultrasonic leak detector uses two independent sensors supported by separate electronic circuits configured specifically to their sensor. This assures optimum sound clarity and frequency response and when switching between the airborne and contact sensors all settings are retained in memory. Digital LED meters lets you establish baselines, perform trending, and accurately repeat these tests better than older more expensive analog instruments.

Overview


The Accutrak VPE-2000 works by detecting the high-frequency sound associated with friction, arcing, and turbulence in industrial systems. By a process called heterodyning, the ultrasonic detector translates the ultrasonic hissing sound to a lower frequency where it can be heard through headphones and leads you to the source. As you get closer, the sound gets louder and/or the LED meter increases. As you close in on the leak, decrease the sensitivity to easily pinpoint its location. Some leaks can be heard from several feet away, therefore direct access to the leak is not always necessary. As long as the leak is turbulent, there will be enough sound to be detected ultrasonically. Ultrasonic air leak detectors can detect pinhole leaks with as low as 1 psi. However, the more pressure behind the leak, the more turbulence there will be, and the easier it will be to locate.

The airborne sensor detects external ultrasonic sound which travels through air vibration. Examples include pressurized gas leaks, vacuum leaks, and external system noise.

The touchprobe sensor detects internal system sounds. Examples include internal valve leaks, bearing wear, and faulty steam traps.

The Superior Accutrak VPE-2000 has two frequency bands for airborne – 28 to 32 kHz and 36 to 42 kHz and three frequency bands for the touch probe – 18 to 22 kHz, 32 to 44 kHz, and sonic 30 Hz to 6 kHz, which allows you to inspect and hear sounds like the running of condensate in a pipe from a steam trap.

Compressors, pumps, and motors contain bearings that are constantly wearing down, and without proper maintenance will eventually fail. The ultrasonic instrument's contact probe is incredibly sensitive to the internal friction within a bearing housing. A digital display indicates the intensity of the sound on a scale from 0 to 255 and can be set to "Peak Hold" to lock in on the reading even with major sound fluctuations. After a few tests, a baseline can be established to use as a comparison for future tests.

As internal bearing components wear, you will see a corresponding trend of increased ultrasonic sound levels. 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.

Ultrasonic leak detectors HVAC can also be used to prevent over or under lubrication while greasing bearings. Induce lubricant until you hear the bearing running smoothly, and relatively quiet, then stop.

The VPE-2000 detects ultrasound and does NOT detect the presence of a specific gas. It is not a gas “sniffer”. Therefore, the digital ultrasonic leak detector can function in areas where heavy wind or a concentration of fumes render other detectors useless.

The Superior Signal VPE-2000 ultrasonic leak detector is constructed of durable ABS, with solid anodized aluminum to house and protect both sensors. The circuit boards are bolted to the case for optimum strength and support. All displays are high intensity for easy readability, and the buttons are sealed to keep out foreign substances. The Accutrak VPE-2000 is made in the USA and built to last.
