Page 4: Introduction Introduction Congratulations on your purchase of the Robinair TruTrack Ultrasonic Leak Detector, the only ultrasonic instrument specifically designed for air conditioning and refrigeration leak detection. TruTrack is the ideal tool for detecting both vacuum and pressure leaks of any refrigerant. Because this instrument detects sound, it is gas-independent. Turbulent flow has a high content of ultrasound, which is above human hearing range but can be heard by TruTrack and traced to its source.

Plug the headphones into the jack located on the right side of the instrument. Slide the sensitivity adjustment all the way forward toward the sensor. The instrument is now set at full sensitivity. If you are trying to find a leak in a confined area, use the flex tube insert located in the nose of the instrument. The amount of sound pressure created by the leak determines its ability to be detected ultrasonically. The TruTrack Ultrasonic Leak Detector detects the most common leaks encountered in refrigeration equipment.

There might be overwhelming background noise, but those sounds are not normally within the detection range of the detector. This sound is not electrical interference—it represents an actual sound that the TruTrack is hearing.

In almost all cases, this sound is not severe enough to interfere with leak detection. Electrical Arcing: A jump in electrical current or ARC makes a popping, frying, or buzzing noise in the ultrasonic range. The TruTrack can be used to locate electrical failures that cause a decline in power quality. Use the detector to test circuit breakers, buss bars, relays, corrosion in contacts, or poor insulation.

The sound generator is placed inside a vessel, such as a walk-in freezer or refrigerated trailer. The sound generator emits a powerful dB ultrasonic tone, which follows the empty passage a gas or liquid would travel to produce a leak.

The detector also produces an audio reproduction of the leak sound. The intensity of the audio changes proportionally to the intensity of the leak sound. The theory of operation of the TruTrack Ultrasonic Leak Detector is based on the turbulent flow of fluids and gases.

Turbulent flow has a high content of ultrasound, which is above human hearing range but can be heard by TruTrack and traced to its source. Turbulence must occur for a leak to be detected.

If a straight piece of tubing is connected to a gas supply and left free to exhaust into the atmosphere, it will not generate any sound if the volume of gas moving through it is too gentle for turbulence to take place. Fluids or gases escaping through openings like this are forced into turbulence—random circular-like motions.

The intensity of sound generated at a leak is a complex combination of the viscosity, temperature, speed the fluid is moving, Raynolds number, pressure differential across the leak, and physical dimensions and characteristics of the crack or hole. Because of these variables, it is possible for a smaller leak to generate more sound than a larger one. Ultrasonic detectors do not indicate a leak if there is no turbulent flow producing soundwaves.

If you suspect a toxic gas,. To prevent personal injury, use another method of verification to ensure no dangerous gases are present. Welcome to ManualMachine.
