Thiết bị kiểm tra rò rỉ bằng siêu âm

    - Advanced, digitally controlled unit!

    - Two LED displays with peak hold.

    - Dedicated touchprobe sensor for optimum sensitivity and sound quality.

    - Separate volume and sensitivity settings.

    - Wide dynamic range increases effectiveness in loud areas.

 

The VPE-1000 uses a dedicated digitally controlled contact sensor for optimum sound clarity.

By detecting the ultrasonic sound created by turbulence and friction in industrial equipment, these extraordinary instruments pinpoint compressed air leaks, vacuum leaks, refrigerant leaks, worn bearings, and internal leaks through valves and steam traps. Our diverse product line incorporates 6 of the most recently issued patents in the field of ultrasonic inspection.

Ultrasonic Leak Detection - You have to hear it to believe it!

The PATENTED AccuTrak represents state-of-the-art technology for pinpointing leaks in air conditioning and refrigeration systems. AccuTrak is extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using a technique called “heterodyning” it translates the sound to a lower frequency which your ear can interpret. AccuTrak maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds. AccuTrak is so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy.

AccuTrak works best when traditional methods fail!

UV dyes/lamps are time consuming, and difficult to use in daylight.
Leaks must be within the users line of sight, as with bubble solutions.
AccuTrak solves the problem!

Electronic refrigerant “sniffers” are sensitive, but sometimes too sensitive when large leaks exist, or if contaminants are present which cause false alarms.
They are also very difficult to use in windy areas.
AccuTrak solves the problem!

Although there were ultrasonic detectors being used in the HVAC/R trade before AccuTrak, poor sound quality, reliability, and sensitivity left many customers dissatisfied with ultrasonics.

Since then AccuTrak has revolutionized the industry leaving our competitors far behind!

Only AccuTrak offers our patented circuitry giving you the best sound quality available. Beeping and squealing ultrasonic detectors let you know that something is being detected, but in areas with background noise, leave you only guessing as to the source of the sound. Other features like the solid contact probe and VPE-1000's digital settings make AccuTrak the smart choice!
AccuTrak simply works better than any other ultrasonic detector in its class! If you don't believe it, we encourage you to try it and compare to any other.
Remember AccuTrak comes with a 30 day unconditional gaurantee. If you don't think it works better than any competitive detector simply return it (in good condition of course). You have 30 days to try the unit risk free!

Sensitivity

The principle of operation of the AccuTrak is based on turbulent flow. For a leak to happen there must be an opening in the system that carries a gas or fluid. Normally, these openings are not clean smooth holes, but passages through cracks with many jagged edges and internal chambers. Fluid or gas escaping through an "orifice" like this, is forced into turbulence (random circular-like motions).

Turbulent flow has a high content of ultrasound. This is sound which is above the human hearing range, but can be heard with the AccuTrak, and traced to its source. It is important to remember that a piece of straight tubing connected to a gas supply and left free to exhaust into the atmosphere will not generate sound if the volume of gas through it is such that turbulence does not take place. Yet for that same flow, an opening as small as 0.005 of an inch could generate enough sound to be heard several feet away.

The intensity of sound generated at a leak is a very complex function of the viscosity, the temperature, the speed the fluid is moving, the Raynolds number, the pressure differential across the leak, and the physical dimensions and characteristics of the orifice. This is why it is possible for a smaller leak to generate more sound than a larger one.

Ultrasonic leak detectors "hear" leaks, therefore the sensitivity can not be accurately stated in terms of cc/sec, parts per million, or ounces per year. The proper specification for these types of detectors is decibels. The amount of sound pressure created by the leak will determine its ability to be detected ultrasonically.

When comparing to gas specific detectors which are extremely sensitive, remember, the instrument was tested under controlled laboratory conditions, and the ability to actually locate small trace gases, especially in a windy outdoor environment is extremely limited. It is physically impossible for an ultrasonic detector to locate a leak such as .5oz per year because there is no turbulent gas flow involved. A leak of .5 oz. per year is equivalent to a loss of 1 pound in 32 years!

Realistically, an ultrasonic detector will detect most of the leaks you encounter on a regular basis. It is the only instrument which will pinpoint a vacuum leak, or detect any pressurized gas in any system. It is also more accurate for detecting larger leaks because its sensor will not become saturated or false alarm from the presence of gas in the atmosphere. Because ultrasonic detectors do not "sniff" out the gas, they can easily locate a leak under windy conditions.

The VPE-1000 is perfect for schools, hospitals, hotels, and other large institutional environments. Use for a variety of leak detection and plant maintenance applications such as Steam Trap Testing, Any Gas Leak Detection, Bearing Wear and Valve Testing.
