Ultrasound Rescues a Super Dryer for Wood Chips
As we were listening to the eighth bearing, we heard a faint ticking sound. The display indicated 2 dB. The guys on site were not worried, as it was only 2 dB. I rephrased this to say…

The Basics of Rigs: the Vital Role They Play in Exploration
Offshore, or marine, rigs are based on sea and onshore rigs are based on land. We select the type of rig based on the geological location and how deep we need to drill. The major concept of rigs is...

Use HD Technology to Manage the Risk of Bearing Faults
Overall vibration catches bearing damage very late, when there may be 0.1% of the bearing lifetime left. Traditional vibration, let’s say systems with poor signal-to-noise ratio...
