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. |
