Quick Tip to Help Locate Compressed Gas Leaks

January 23, 2018

Using ultrasound to locate compressed gas leaks is relatively easy, but it occasionally it can present some challenges. The reason ultrasound is so successful is that it is a high frequency, short wavelength signal that does not like to penetrate 2nd mediums. While performing compressed gas leak inspections, keep in mind that strong ultrasonic signals […]

Ultrasound Finds Worn and Misaligned Couplings

January 9, 2018

Simon is a condition monitoring specialist from a local oil refinery. He contacted my office for advice about predicting flexible coupling failures. Currently, they perform basic vibration analysis on their pumps and motors using an overall meter. They have some success predicting bearing failures but the same cannot be said for couplings. Several unexpected failures […]

Is your Application FIT for Ultrasound?

September 26, 2017

I often hear the question, “what can I detect with ultrasound?”. The fact is, ultrasound is such a versatile condition monitoring technology we tend to ask it to do things beyond its capabilities. And that’s fine because I firmly believe every technology should be pushed beyond its limits. It’s how we get better. But to […]
