Ultrasonic Leak and Corona Detector

DESCRIPTION

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.

Using the Detector

With the transducer probe plugged into the instrument, the

operator can immediately locate many ultrasonic sources

by scanning with the transducer probe held as a flashlight

and using the speaker or meter to detect maximum

emissions. For greater sensitivity, or to further pinpoint a

distant source, the operator simply slips the directional

horn over the transducer. The focus is now greatly

concentrated, permitting source location to within a

1-ft (0.3-m) circle at 30 ft (9 m). If the source can be

approached, the rubber sound concentrator is slipped over

the transducer probe, pinpointing a source to within its tip

diameter of about 0.5 in. (13 mm).

Pickup Horn Operation

The pickup horn

amplifies signals

originating within

the response beam

and rejects others.

The ultrasonic transducer in the probe responds primarily

to a 35- to 45-kHz bandwidth—a range found most useful

for the tests described here. The transducer is very

insensitive to audible sounds, allowing use of the

detection system in areas with high audible background

noise levels.

The output meter, for indicating ultrasonic sound intensity,

is calibrated with a 0-to-10 linear scale, showing relative

level. Power is from a 9-volt transistor battery, and a single

on-off volume-control switch is provided.

APPLICATIONS

The Ultrasonic Leak and Corona Detector is useful

wherever electrical or pressurized equipment is used.

Applications include preventive maintenance in plants and

utilities to locate poor or arcing connections, switches,

faulty insulators, lightning arresters, power supplies,

motors and radio frequency interference sources. In the

test laboratory, the set is useful in performing high-pot

tests on components of all sizes and for high-voltage

equipment tests. Early detection of leaks by preventive

maintenance checks in compressed air systems, boilers and

air-conditioning equipment will provide savings in reduced

equipment replacement and downtime.
