The Ultrasonic Leak and Corona Detector is a low-cost, portable system that receives air-borne ultrasonic signals, converts them to the audible range, amplifies them and displays the output visibly on a meter and audibly through a speaker or headset. The system is designed for locating gas leaks and electrical corona sources, all of which emit strong ultrasonic signals that are inaudible to the unaided human ear. Variously shaped collectors facilitate quick location of ultrasonic sources; in particular, the new directional pickup horn allows pinpointing of discharges in high-voltage equipment while the operator remains at a safe distance.The ultrasonic detection system shown above consists of the instrument with indicator and speaker, plug-in ultrasonic transducer probe, directional pickup horn attachment, sound concentrator attachment and a headset. A carrying case is included.
Ultrasonic Tone Generator Option
For testing non-pressurized items such as tanks and pipes for faulty welds, seams, seals and gaskets, the tone generator is placed inside the item to be tested, filling the area with ultrasound (35 to 45 kHz). Sound will leak through any openings. The detector is then used to scan the outside of the test object, pinpointing the leak location.
The tone generator is powered by a standard 9-volt transistor battery.
Contact Probe
This probe is used to detect ultrasonic signals in environments other than air. The contact probe is extremely useful for detecting faulty steam traps, worn bearings, worn gears, etc.
