The EP 542 ultrasonic detector equipment, which is mainly used for most general applications within industrial plants, consists of: a detecting device with higher sensitivity than the EP 300 ultrasonic detector series.

EP 911 - Headphone
EP 931 - Directional probe
EP 941/EP 942 Stethoscope sensors

The EP 542 ultrasonic detector is used to find leaks (e.g. in compressed air installations, vacuum installations, in tanks, pipe systems, car windows, etc,.) Also locates arcing and corona discharge in electrical systems as well as to find mechanical malfunctions on movable parts (e.g. ball bearings, gears, etc.).

The EP 542 ultrasonic equipment 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 e.g. ultrasonic. Audible noises from the surroundings are filtered off so that the device can also be used in noise filled areas.

If leaking 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 minute" leak the directional probe can be applied to the sensor at the top of the instrument and optimum listening-sensitivity is achieved.

Make sure to seal all the leaks found at the examination as leaks cost money!

The EP 542 ultrasonic detector works also as a "mechanical malfunction feeler" 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.

EP 542 ultrasonic detector can be used with the EP 512 - ultrasonic transmitter (see picture above) that transmits pulsating ultrasonic. The transmitter is placed inside an enclosure, e.g. a steel tank, that is then closed. The user can then examine the tank from the outside perimeter (range 22 m) and can easily find any leaks, if any, which sounds like "pips" in the headphones.

If requiring a detector with an extremely higher listening sensitivity we recommend the EP 2000 ultrasonic detector.

Noise filled areas: If the noise level exceeds 80 dB we recommend using an authorized and CE approved EP 921 - hearing protector.

Scopes of application: industrial plants, workshops, laboratories, hospital service, aeroplane industry, cars, etc,..

Accessory equipment:

EP 542 ultrasonic detector can be combined with EP 512 - ultrasonic transmitter.

EP 542 ultrasonic detector can also be connected with an authorized and CE approved EP 921 hearing protector.

There is a 2 year warranty on all EP ultrasonic detectors.
