Ultrasonic detector for airborne
ultrasound
Used to locate leaks, detect electrical emissions and also inspects mechanical conditions in operating equipment, in many various industrial plants
A predictive maintenance/energy conservation technology called Airborne/Structure Borne Ultrasound is used to locate leaks, detect electrical emissions and also inspects mechanical conditions in operating equipment, in many various industrial plants Instruments, such as the EP2400 ultrasonic leak/stethoscope detector is based on this technology

Ultrasonic leak detector for maintenance personnel
Energy wasted in compressed air is common in industry, and also expensive - making it sensible to continuously inspect air, vacuum, and gas installations for leaks
This detector receives high frequency sounds that are above human perception (20 kHz-100 kHz) and electronically translates them down into the audible range where they can be heard through headphones (and even without headphones gives of a audible signal) and seen as intensity increments on a small display panel.
Typical applications of the EP2400 ultrasonic detector set include compressed air leak detection, vacuum leak detection, steam trap inspection, mechanical condition inspection, bearing and gear testing and detection of arcing, tracking and corona in electrical equipment.
What is so effective about airborne ultrasound? With all operating equipment, most leakage and electrical problems produce a broad range of sound.

The high frequency ultrasonic components of these sounds are in nature, extremely short wave.
A short wave signal tends to be fairly directional.
It is therefore simple to isolate these signals from any background plant noises and to detect their exact location.
In addition, as slight changes begin to occur in mechanical equipment, the directional nature of ultrasound allows these potential warning signals to be detected in time, before actual failure occurs.
The EP2400 ultrasonic leak/stethoscope detector allows maintenance personnel to confirm a diagnosis on the spot by being able to clearly discriminate among various equipment sounds.
This is accomplished in most ultrasonic translators by an electronic process called 'heterodyning' that accurately converts the ultrasounds sensed by the instrument into the audible range where users can hear the audible signal or recognise them through headphones.
The high frequency, short wave characteristic of ultrasound enables users to (i) accurately pinpoint the location of a leak or (ii) a particular sound in a machine.
The basic advantages of ultrasonic instruments are that they can easily locate leaks, provide advanced warning of impending mechanical failure and can be used in loud, noisy environments.
The EP2400 ultrasonic leak/stethoscope detector is handheld, portable and a essential instrument to be within all industrial plants. Request a free brochure from Logis-Tech Associates ...
