A Note About Sensitivity
Ultrasonic leak detectors “hear” leaks; therefore, the sensitivity is
accurately stated in terms of decibels. 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. Left untreated, these leaks would
result in the loss of several pounds of refrigerant into the atmosphere
over a period of time. The TruTrack Ultrasonic Leak Detector is the only
detector that pinpoints a vacuum leak and also detects any pressurized
gas leak in any system. It is also more accurate for detecting larger leaks,
because its sensor does not become saturated with refrigerants or set off
alarms due to refrigerant gases in the air.
The Contact Probe Accessory (16456)
The TruTrack Ultrasonic Leak Detector detects sound that travels through
solid materials as well as air. The contact probe accessory is used to
detect sounds that are internally generated.
Such sounds include abnormal ow in piping, leaks through bad valve
seats, and steam trap leaks. Other applications include the detection of
friction, lack of lubrication, and worn bearings, motors and gears. The
probe physically converts sound within a solid to an airborne frequency.
Once airborne, the signal is concentrated and projected into the sensor of
the TruTrack Ultrasonic Leak Detector.
Using the Contact Probe:
1. Unscrew the existing nosepiece, and screw on the nosepiece
containing the contact probe.
2. Place the tip of the probe onto the item being tested with just enough
force to hold it in place.
