Superior AccuTrak VPE Basic Ultrasonic Leak Detector

Part Number: VPE BASIC
0 Review(s)
The Superior AccuTrak VPE Basic Leak Detector Ultrasonic is an all-in-one leak detector for all HVAC/R and automotive projects. The sensitive ultrasonic detector is not just limited to one type of signal, but can detect air, vacuum, refrigerants, and any gas. The Superior AccuTrak VPE-BASIC Leak Detector Ultrasonic emits a low frequency easily heard by the human ear as well as a 10 element bar graph for visual indication. The kit includes headphones, a 9v battery, and a hard case for durability.

AccuTrak VPE Basic Ultrasonic Leak Detector


The Superior AccuTrak VPE Basic Kit is a non-invasive cost-effective ultrasonic leak detector that can detect both pressure and vacuum leaks of any gas. The VPE Basic Kit leak detector is ideal to easily and effectively pinpointing leaks in air conditioning, refrigeration, automotive, and other systems. Ultrasonic Leak detectors are extremely sensitive to the ultrasonic sound of a turbulent gas leak. Superior ultrasonic leak detectors use a technology called “heterodyning” which translates ultrasound to a lower frequency which your ears can interpret. The Accutrak Basic Kit Ultrasonic Leak Detector maintains the original sound characteristics of the ultrasound making it possible to distinguish leaks from other competing background sounds. The Accutrak instruments are so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy. The Superior VPE Basic Kit Ultrasonic leak detector includes headset, and a carrying case. Listed below are the AccuTrak VPE Ultrasonic Leak Detector kits available and what is included in each one.

Applications:


Leak Detection: Air, Vacuum, Refrigerants, ANY GAS!

Overview


The VPE Basic Kit Kit detects ultrasound – not refrigerant, or the presence of a specific gas. Any turbulent gas will generate ultrasound when it leaks, therefore it does not matter what gas you are leak testing. The Accutrak ultrasonic air leak detector will detect air, nitrogen, compressed air, new or old refrigerants, or even air as it rushes into a system. It is a listening device not a “sniffer”. Therefore, the AccuTrack VPE can function in areas of heavy wind or concentrations of fumes from leaks which would make other detectors inoperable.

It is also more accurate than other types of detectors for detecting larger leaks because its sensor will not become saturated or give false alarms from the presence of gas in the atmosphere.

A leak is any unwanted flow of a substance out of a system, or in the case of a vacuum the unwanted flow into the system. This flow in or out of a system creates friction which generates an ultrasonic sound. The amount of turbulence present at a leak site is a function of the size of the orifice, the pressure behind the leak, the shape, or physical geometry of the orifice, as well as the type of pipe or container holding the gas. These factors will all determine how much ultrasonic sound will be produced by a given leak. It is quite possible for a smaller leak to create more turbulence (and sound) than a larger leak.

The sounds we can hear are less than a third of the total spectrum of frequencies generated. The sound in small leaks is mostly ultrasonic. Humans cannot hear this because it is above the human hearing range. The amount of sound pressure created by the leak will determine its ability to be detected ultrasonically. In order for a leak to generate ultrasound, the flow through the leak’s path must be turbulent.
 
The VPE ultrasonic sound detector receives the ultrasonic sound that escapes from a leak point, converts the sound down to the audible range where it can be heard in a headset, and viewed on the meter’s 10-element bar graph. The larger the leak, the higher the volume will be in the headset as well as a higher indication on the bar graph. This ultrasonic leak detector not only allows you to hear the leak, but also see the leak on the graph, helping to easily pinpoint the exact location of the leak. In addition, it also has a burst mode to make the output of the sound easier to identify for locations that have extremely noisy backgrounds.
 
The “Peak Hold” function on the leak detector can be toggled on or off by pressing the ON/OFF button. This function can be useful to better observe the maximum strength signals being detected, helping to locate leaks and faults.

The Accutrak VPE is capable of hearing leaks from over forty feet away, but it is best to hold the instrument as close to the test area as safely possible and check around fittings and piping using a zigzag motion, covering all suspected areas carefully.

Depending on your applications, you might want a kit that includes the Touch Probe. The Touch Probe accessory (included in VPE Standard Kit, VPE Professional Kit, VPE Plus Kit, and VPE Pro-Plus Kit) allows a technician to detect sounds that are internally generated, such as leaks through bad steam traps and bad valve seats, as well as locating friction, worn bearings, motors, and gears. The VPE utilizing the Touch Probe can troubleshoot thermal expansion valve in less than 5 minutes.

The Superior AccuTrak VPE Basic Kit Ultrasonic Leak detector is made in the USA and offers great versatility as well as extraordinary functional performance to locate leaks in most environments.
