Detector finds leaks, identifies wear,
saves costs
Ultrasonic detector makes great savings in all industrial plants by detecting leaks in compressed air or gas systems and vacuums and identifying mechanical malfunctions like worn bearings.
Many companies today are under tremendous pressure to reduce costs while still wishing to maintaining production levels or even increase production levels The goal of Predictive Maintenance is to assist the management of plant in optimising the maintenance expense

Air compressor costs rising? Then check for leaks!
Using a leak detector to check an existing compressed system will immediately improve system performance and realise notable savings in energy consumption.
Too much data drives up costs without yielding more effective data, and clouds the decision process by having an information overload.
In the middle is optimised maintenance.
One such instrument The EP2400 ultrasonic detector makes great savings in all industrial plants in two ways: substantial energy savings (detecting leaks in compressed air or gas systems, vacuums, steam traps, tanks, window seals etc) and mechanical malfunctions (detection of worn bearings, gears, mechanical movable parts within casings etc).
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 used in noisy environments.
The EP2400 ultrasonic detector also has a new 'ultra search' technology incorporated, which improves both close leak seek and the detection of leaks at a distance (up to 6m).
The detector now offers both analogue and digital leak detection.
When using analogue leak detection (with hearing protector) 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 at 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 unit 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 transmitter can also be used in conjunction with an EP512 ultrasonic transmitter that transmits pulsating ultrasound.
The 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 from 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 industrial plants. Request a free brochure from Logis-Tech Associates ...
