Metrology, simply, is the science of measuring things. Metrology is used extensively in the world of industrial cleaning to both control and quantify cleaning processes. Finding the right equipment and procedures to produce accurate and meaningful results is often a challenge for those without extensive knowledge of the science. The upcoming blogs on metrology are …
Deep in a file drawer in my office on a couple of pieces of paper yellowed by time is an article that, written and published in 1954, is a literal snapshot of the notion and perceived traits of an engineer over 50 years ago – when I was only 9 years old. Every once in a …
Sweep in ultrasonic lingo simply means varying the ultrasonic frequency up and down. A sound clip in an earlier post demonstrated the sound of sweeping the ultrasonic frequency. Single Frequency Sweep In an earlier post we also learned that ultrasonic transducers have a property called “resonance.” Very simply, this means that they will make a …
As some of you may have noticed, the illustrations in Monday’s (30 April, 2012) were incorrect. For those of you who didn’t notice, that’s OK – because I didn’t either. It is interesting how much more thoroughly you understand something once you’ve tried to convey it to someone else. Regular readers will know that I, …
In today’s blog we once again bring ultrasonic sounds into the range of human audibility and listen to the sound of frequency sweep. Previous blogs have revealed the sound of amplitude modulation and pulse modulation. Frequency sweep is all about frequency – ideally there is no change in amplitude as frequency is varied. In some …
The preceding blog described the benefit of part agitation in a cleaning process. But, it is not always possible to provide adequate part agitation with a simple agitation of the part parallel to its central axis. With a little creativity, it is possible to provide effective agitation of even very long parts. In fact, there …
Inadequate or improper agitation of parts in a cleaning tank is a common problem in industrial cleaning. Agitation, if properly applied, can be a very powerful aid to cleaning. The result of improperly applied agitation, however, can range from disappointing to disaster. The basic reason to agitate a part in a cleaning tank is to provide or …
The specification of automated valves requires certain considerations that are not of concern with typical manually operated valves. The blog Valves – Automated Valves – What’s Different? provided a glimpse of automated valves with a very simple (but typical) example. There are, of course, innumerable variations used in the design of automated valves so the …
Today’s highly automated industrial cleaning equipment relies heavily on valves remotely actuated either by an operator or by an automated control system. Although performing basically the same function as manually operated valves, automated valves operated by electricity, air, hydraulics or other means are considerably different than manual valves not only in their construction but their mode …
I’ve been “playing” with ultrasonics for over two-thirds of my life now and am absolutely convinced that there is still more to know about the technology than anyone knows. The “fish tank” in the lab continues to reveal more questions than answers when it comes to this complex technology. The Ultrasonic Fish Tank in the Lab Still, …
