Ultrasonic detector reduces maintenance costs

Handheld, portable, highly sensitive, simple to use ultrasonic leak/stethoscope device detects leaks in compressed air or gas systems and mechanical and electrical malfunctions.

Logis-Tech Associates reports a 40% increase in sales of its EP2400 ultrasonic leak/stethoscope detector from April to March 2005, compared with the same period in 2004.

Managing director, Hugo Gallagher believes this is because the handheld, portable, highly sensitive, simple to use, device can repay its initial cost outlay - tenfold.

The EP2400 ultrasonic detector makes great savings in all types of manufacturing plants in three ways: (1) Substantial energy savings (detecting leaks in compressed air or gas systems, airlines, vacuums, steam traps, tanks, window seals etc) - no more spraying.

(2) Mechanical malfunctions (detection of worn bearings, gears, mechanical movable parts within casings, etc).

(3) Also locates arcing and corona discharge in electric systems.

The EP2400 ultrasonic detector works by 'listening' in a frequency band normally containing no interference and inaudible to humans (above 20kHz).

Leaking compressed air or electrical flashover (sparks) generates ultrasonic noise.

Audible noises from the surroundings are filtered off so that the device can also be easily used in noisy environments.

The EP2400 ultrasonic detector also has a new 'ultra search' technology incorporated, which improves both close leak seeking and the detection of leaks at a distance (works comfortably detecting leaks up to 6m).

The detector now offers both analogue and digital leak detection.

When using analogue leak detection (with hearing protector fitted) a 'buzz' can be heard in the headphone, and the sound level depends on the size of the leak.

If looking for a very 'small' leak close by, the directional probe can be applied to the sensor at the top of the instrument and optimum listening sensitivity is achieved.

The analogue detection is very precise, both close and at distance.

When using digital leak detection (without hearing protector): the unit makes use of a newly developed digital technology, where the ultrasound transforms into a digital signal which the user sees and hears from the EP2400 ultrasonic detector as a flashing light and a pulsating sound.

The faster the light flashes and the sound pulsates the closer the detector is to the leak, and this speed is also an expression of the size of the leak (the faster the pulsation - the bigger the leakage).

Digital leak detection is very fast and handy, but not as precise as analogue detection.

It is of the utmost importance to make sure and seal all the leaks found at the examination as leakage costs money.

The EP2400 ultrasonic detector also works as a 'mechanical malfunction troubleshooter'.

It picks up interference from movable parts through a stethoscope or a clip.

The stethoscope only 'listens' to low-frequency mechanical vibrations so the stethoscope can also be used in noisy areas.

The EP2400 ultrasonic detector can also be used in conjunction with an EP512 ultrasonic transmitter.

The EP512 ultrasonic transmitter transmits pulsating ultrasound.

The EP512 transmitter can be placed inside the unit under test, for example a steel tank, that is then closed.

The user can then examine the tank from the outside and can easily find any leaks, which sounds like 'pips' in the headphones.

The EP2400 ultrasonic detector is now selling worldwide.

It can be used in very noisy environments and is an essential and necessary tool for all maintenance/service staff working in all types of manufacturing plants.
