Device detects leaks and mechanical
problems
Ultrasonic double (leakage and stethoscope) detector set finds leaks in compressed air installations as well as mechanical malfunctions on movable parts like ball bearings.
The EP542A ultrasonic double (leakage and stethoscope) detector set is used to find (1) leaks (e.g in compressed air installations, vacuum installations, steam traps, tanks, etc) as well as to find (2) mechanical malfunctions on movable parts (e g ball bearings, gears, etc) The ultrasonic double detection equipment EP542A works by 'listening' in a frequency band normally containing no interference and non-audible for humans (>20kHz)

Check for air leaks and save energy costs
Wasted energy in compressed air is quite common. It is therefore sensible to continuously inspect the company's air, vacuum or gas installations on a frequent basis.
Qualify to HNC standard in your spare time
A technical training operation provides a service for those who are unable to attend college on either a full-time or part-time basis for HNC engineering courses.
Leaking compressed air or electrical flashover (sparks) generates e g ultrasonic.
As a mechanical malfunction feeler, the EP542A 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.
It takes only five simple steps to use the EP542A ultrasonic double detector for leakages and five simple steps for mechanical malfunctions: Ultrasonic: 1.
Fit the pin from the headphone into the front of the detector in the yellow plug (Hearing protectors).
2.
Push the button with the text "Ultrasound" down and hold it there.
3.
Lead the sensor at the top of the detector over or past the desired parts to be examined.
4.
If there is a leak, a 'buzz' will 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.
5.
Finally, make sure and seal all the leaks found at the examination as leakage costs money! Mechanical noise: 1.
Fit the pin from headphone into the front of the detector in the yellow plug (Phones).
2.
Screw the short or the long stethoscope (depending on the task) to the top of the detector.
3.
Place the stethoscope at the item to be examined (eg, motor casing, etc).
4.
At the EP542A the button with the text "Stethoscope" is pushed down and held down.
5.
Concentrate on the mechanical noise.
In some cases the user has to spend some time to sort out other mechanical noises and between these e.g hear a damaged bearing.
Concentrate on strange noises and heterogeneity and remember ~ practice makes perfect! This ultrasonic double handtool is a neccessary piece of equipment for all maintenance staff in all manufacturing plants and repays its cost many times over. Request a free brochure from Logis-Tech Associates ...
