英文介绍: The XLG-80 detector was designed for several Industrial trouble shooting applications such as pressurized telephone cable leaks from pressurized cable in the telephone industry are at such low pressure they are outside of the human hearing range. The combination of the transducer and control box of the XLG-80 converts the sound so that it is unmistakable when the ultrasonic transducer is pointed at or close to the source.
Corona Discharge. Prior to visible arcing, there is an electrical discharge which sound like Vigorously frying bacon when perceived by the XLG-80.
Bearing Wear. Long before vibration sounds are apparent, charges in the volume of ultrasonic sound are an early indication of bearing failure.
Steam Traps. The functioning of a steam traps including ”blow-bys” “machine gunning, leakage, blockage and oversized traps can all be determined ultrasonically without interference from other nearby sounds.
Valves. Closed valves, which are seated property, emit no sound. The slightest flow from a liquid or gas valve can be detected ultrasonically.
Gaseous Leaks Small air, nitrogen, helium and other nonflammable and nontoxic gas leak are easily sensed with the XLG-80, Larger gaseous leak are in the sonic range and can be heard easily without instrumentation. Do not use the XLG-80 for detecting flammable or toxic gas leaks.
Water Leaks. Water companies and liquid leak detection professionals can make use of the XLG-80. If they add air to a water system to cause a distinct” sputtering at the leak location. The sputtering and whistle sound are usually in the ultrasonic range.
An optional transmitter can be used with the XLG-90 or XLG-80 to sense weakened areas and pinholes in tanks.
Features Inexpensive but complete kit for ultrasonic sensing. Compact control box that can be worn: on the belt, around the neck, or over the shoulder with attachable strap.
Minimum number of controls for a user-friendly control panel. Listening is loudness limited to lessen sudden blasts of uncomfortable sound.
