Watts of ultrasonic generator output power is one metric often used in the comparison of ultrasonic cleaning systems. In a previous blog, I discussed the potential foibles of using watts of consumption as a measure of comparison as there is no standard for measuring the output of an ultrasonic generator. But there are also other …
More is better in some cases but when it comes to chemistry in industrial cleaning, using too much is costly and could indicate process problems as well. Cost – First, there is the obvious cost of using more chemistry. Most aqueous cleaning chemistries range in price from $15 to $40 per gallon but may exceed …
I sometimes reflect the purpose of John’s Corner. It’s really pretty simple – to help those who are interested in industrial cleaning to understand and make the best use of the existing industrial cleaning technology – but maybe it’s more. As most of you may know (it is no secret), I am a former employee …
Nearly anyone who has been involved in the procurement of an ultrasonic cleaning system has come head to head with watts of ultrasonic power issues. Variations of an order of magnitude or more are common in ultrasonic watts ratings from competitors selling equipment of otherwise similar size and capacity. Despite the discrepancies, I don’t believe anyone …
“Millipore” testing is a popular way of quantifying part cleanliness today. What is generally not known, however, is that it is far from an absolute standard and, in fact, can be very misleading even if “properly” applied. Part of this may be due to the genesis and heritage of Millipore testing. At its inception, Millipore …
Inductors and capacitors both provide short term storage of electrical energy but in different ways and with different goals. A capacitor physically stores electrons and acts as a source of voltage. An inductor stores electrical current in a magnetic field and acts as a source of current. Although not present in all inductors, a core …
Both capacitors and inductors are “reactive” components. Unlike resistors, capacitors and inductors store electricity on a short term basis but in different ways. For me, the capacitor is a little easier to understand so let’s start with it. For all practical purposes, capacitors consist of two pieces of conductive material (think aluminum foil) separated by …
