Ultrasonic Pressurised Gas leak Detection

Production line image of GDUsUltrasonic/ Acoustic gas detectors instantly detect gas leaks by 'hearing' the sound generated by escaping gas rather than responding to specific measurements of LEL or ppm.

It is the only method of detection able to detect gas without the gas cloud needing to come into direct contact with the detector. The technology is impervious to wind, fog or gas dilution and is therefore very reliable in outdoor installations.

Our intrinsically safe and flameproof sensors use the proven ultrasonic method of gas detection. These sensors will detect gas at ‘the speed of sound’.

If you are planning to use ultrasonic gas leak detectors, it as advisable to first carry our an ultrasonic mapping survey to monitor background ultrasonic noise levels and determine best positioning of the detectors.

For more information on the ultrasonic mapping surveys we provide please go to our ultrasonic mapping services page.

GDU-Incus

GDU-IncusThe GDU-Incus is the latest product to expand our range of ultrasonic pressurised gas leak detectors. Utilising an advanced form of piezo-electric sensor technology, the GDU-Incus incorporates four independent sensing heads designed to allow unobstructed sensing and a vast detection range.

  • Explosion proof/flame proof certification plus SIL2 certified

  • Works in the harshest of environments from -55° to +85°C

  • Incorporates a unique integral self testing and cleaning system

Unlike any other detector, each sensor head can be tested with a true pressurised gas leak to simulate actual site detection capability. The self cleaning feature removes any build up of contaminants such as sand, oil or dust - minimising the level of maintenance required.

GDU-01

GDU-01 ImageThe GDU-01 is an Omni-Directional intrinsically safe airborne leak detector designed for detection of pressurised gas leaks. The detector responds to the ultrasonic sound generated when leakage occurs from an area of high pressure to low pressure. A pressure difference of only 2 bar or above is required.

  • Detects all pressurised gas leaks
  • Instantaneous Speed of response
  • Large area of coverage

The GDU-01 uses piezo-electric sensing technology to provide high sensitivity and levels of immunity to environmental elements.
