The EP 542 ultrasonic leak detector is fast becoming the top seller for Logis-Tech Associates.
The EP 542 ultrasonic leak detector is fast becoming the top seller for Logis-Tech Associates.
The company reckons the detector can quickly repay its initial cost outlay, save substantial energy costs and improve companies' overall efficiency.
Throughout all industry, wasted energy in compressed air is quite common.
However compressed air (and other gases) are at the same time a very large cost to the company's budget each year.
It is therefore sensible to continuously inspect the company's air, vacuum or gas installations on a frequent basis.
Portable fault locating ultrasonic detectors are ideally suited, especially in noisy environments, to be used in energy conservation, predictive maintenance and proactive maintenance programmes for leak detection and mechanical inspection.
The EP 542 ultrasonic leak detector is: portable and handheld; quick and reliable; and safe and convenient.
Applications include testing of bearings, gears, boxes, tanks, pipes etc.
It is ideally suited in noisy environments for energy conservation and predictive and proactive maintenance programmes.
The EP542 is used to find leaks (eg in compressed air installations, vacuum installations, in tanks, on car windows etc) as well as to find mechanical malfunctions on movable parts (eg ball bearings).
As ultrasonic equipment, the EP542 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 e.g ultrasonic.
Audible noises from the surrounding areas are filtered off so that the device can easily be used in this type of environment, ie noise-filled areas.
If a leak is found a "buzz" can be heard in the headphone.
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.
It is imperative to make sure and seal all the leaks found at the examination - as leakage causes a loss in efficiency and costs a lot of money.
As a "mechanical malfunction feeler" the EP542 picks up interference from movable parts through a stethoscope.
The stethoscope only "listens" to low-frequency mechanical vibrations so the stethoscope can also be used in noisy areas.
The EP542 can be used with the EP512, an ultrasonic transmitter that produces pulsating ultrasound.
The transmitter is placed inside the item, such as a steel tank, which is then closed.
The user can then examine the tank from the outside and can easily find any leaks, if any, which sound like "pips" in the headphones.
