Ultrasonic leak detector for maintenance personnel

Edited by the Laboratorytalk editorial team Jul 2, 2002

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

The EP542 ultrasonic leak detector is fast becoming the top seller for Logis-Tech.

The detector is said to quickly repay its initial cost outlay, saving companies substantial energy costs and improving 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 electronic/mechanical inspection.

The advantages of the EP 542 Ultrasonic leak detector are: portable and hand held; quick and reliable; safe and convenient; testing of bearings, gears, etc; testing of boxes, tanks, pipes, etc; ideally suited in noisy environments; energy conservation; predictive and proactive maintenance programmes.

The equipment is delivered in a suitcase and consists of: 1 - EP542 detecting device with higher sensitivity than EP300 series.

1 - EP911 headphone.

1 - EP931 directional probe.

2 - stethoscope sensors (EP941-short and EP942-long).

1 - operating instructions.

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 EP542 works by listening in a frequency band normally containing no interference and non-audible for humans (>20 kHz).

Leaking compressed air or electrical flashover (sparks) generates 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.

EP542 can be used with EP512 ultrasonic transmitter that transmits pulsating ultrasonic.

The transmitter is placed inside the item, eg 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.

If requiring a detector with an extremely high listening sensitivity Logis-Tech recommends the EP 2000 detector.

Noise filled areas: If the noise level exceeds 80dB it recommends using an authorised and CE approved EP921 hearing protector.

Scopes of application: All types of industrial plants and factories, building maintenance, laboratories, hospitals, etc.

Accessory equipment: EP542 can be combined with EP512 ultrasonic transmitter and connected with an authorised and CE approved EP921 hearing protector.
