Ultra Sonic Leak Detection

Acoustic Emission is a relatively new tool in the Condition Monitoring toolbox. However it is already beginning to show new ways of making cost savings and optimising machinery and plant performance by sensing high frequency sounds created by operating machinery, leaks and electrical discharges.

Since the ultrasonic frequency range is being tested there is no interference from the background noise of your site - it’s simply filtered out. By doing this we can detect all kinds of defects that would normally only be found at an outage or weekend. The survey is non-intrusive and requires no special permits or changes to your production cycle.

Pressure and Vacuum leaks

Any gas passing through a leak generates a turbulent flow that can be detected at ultrasonic frequencies. Over a site the total amount of leaks could contribute to a substantial portion of your annual gas/fluid cost. Identifying and fixing these leaks will bring you direct savings, and indirect savings from less power usage (compressors), reduced maintenance, and reducing ambient dB levels in your workplace.

Did you know that a 1/8" hole in a pressurised air line could be costing as much as £1500.00 per year? Interface Condition Monitoring Ltd can identify, report, and recommend on ways to fix these leaks and reduce your costs.

Valve leaks and blockages

Valve activity such as leaks and blockages can be checked whilst the valve is on-line. A leaking valve produces a turbulent flow past the valve that can be detected within the ultrasonic range. By using a wide sensitivity and ultrasonic frequency all types of valves can be checked.

Steam Trap Inspection

Ultrasound is recognised as being the most reliable form of inspection by many steam trap manufacturers. By listening to the ultrasonic range whilst the steam trap is on-line we can detect blowby, machine gunning, oversized traps and line blockage.

Heat Exchangers, Boilers and Condensers

In-leakage and pressure leakage can easily be tested for within the ultrasonic range. Fittings, valves and flanges are all easily and quickly scanned for leakage. Condenser tubes and heat exchange tubes can also be tested for leakage by using Vacuum and Pressure.

Bearing defects (low speed to 0.5 RPM)

Ultrasound and Acoustic Emission can be utilised to detect bearing defects down to frequency ranges that were previously impossible using vibration analysis. By sensing very high frequencies it is possible to detect the shock waves that are produced inside a machine that is under stress. This makes it possible to detect very early signs of bearing damage and to schedule remedial work. This is often critical in slow speed applications where large bearings are typically not stock items and have a long lead time to delivery.

Electrical defects

When an electrical problem exists common symptoms such as arching and corona discharge emit ultrasounds at the site of emission. This can be detected quickly and safely whist the machine is on-line. Switch gear, buss bars, transformers, circuit breakers, relays, junction boxes and other electrical gear can all be included in your survey.
