Switched Mode Power Supplies (SMPS) use control loops to ensure that the working point is obtained with the minimum steady state error and fast transient response. To achieve these objectives, a strong control action is needed. But if this action is too aggressive, it can make the system unstable, lead to oscillations that can increase ripples, component stress or even d...

What is bubble tea? Bubble tea, a Taiwanese drink that has become extremely popular around the world, is a type of tea that is mixed with sweetened milk, fruit juice or other flavoring. The bubbles in the tea come from the tapioca balls added to the drink. These small balls of starch expand when they are put in hot water and add a unique texture to the drink. Traditional...
Mission-critical semi-rigid cable assemblies are a coaxial cable with a outer conductor formed from a solid seamless metal tube – usually copper or aluminum. Within the metal tube there is a metal wire conductor running down the center of the tube which is wrapped and supported by a dielectric (tubular insulating layer) material keeping the wire centered in the tube. The...

Co-extrusion is the creation of a multi-layer system, obtained by feeding the extruder head with more than one material, each coming from a different cylinder. Passing through the die, the different flows are organized and compose the different layers of the object. On a physical level, this is guaranteed by the viscosity of the polymers, which prevents mixing and allows...
In many circumstances, it makes perfect sense to use extra-low voltage relays, even if what’s being controlled runs on mains voltage. However, while the benefits of using an SMPS are often clear, it is also important to review how to design such a type of power module. Below we will review where to start in the design of a switch-mode power supply.

I am often asked about compressed air leak inspections… how often should compressed air leak inspections be carried out, should they occur during planned outages or regular operation hours, should the whole plant be inspected at once or should it be broken up into smaller more manageable sections. Here are my recommendations for carrying out a successful compressed air ...
linear motion design Linear motion is an area of motion control encompassing several technologies including linear motors, linear actuators, and linear rolling guides and bearings, among others. Linear motors — an accurate option Traditional linear motors are basically a permanent magnet rotary motor rolled out and laid flat. It’s as if the stator and rotor were cut...
We know one lubrication mistake can mean hours, even days of unplanned downtime… because we’ve seen it happen. Lubrication related failures are especially difficult to plan for because one wrong move can rapidly deteriorate the condition of a bearing, causing failure within hours of the mistake. With any luck, the necessary parts for repair will be in stock, but that is...
A study done by the National Research Council of Canada found that 82% of bearing wear is caused by particle contamination. This makes lubrication contamination the leading cause of premature failures. Lubrication contamination occurs regardless of industry, geographic location, facility size, standard operating procedures, and the training and experience of the mainten...

Bearings are the driving force behind industry, and it is the grease that helps them run smoothly and last longer. While almost every plant in the world has rotating equipment and almost every maintenance technician is familiar with bearing grease replenishment, bearings are still a sadly misunderstood asset. Which is why as much as 80% of all bearings fail prematurely....
Yet the fact remains that compressed air remains the most misunderstood and abused source of power in manufacturing today. Compressed air system leaks are our biggest challenge for optimization. They are a wasteful way to add unnecessary demand to these maxed out systems. Operations demand a consistent supply of pressure and capacity in their compressed air systems. They...
18 pumps under the responsibility of a Condition Monitoring team, demonstrating an almost identical behavior, with identical symptoms… and surely calling for full attention.

Firstly, I looked at all the Ultrasound data one by one, and all of them looked quite similar ...
Both, PTP and NTP provides time synchronization over a packet-based network. But not both protocols are dedicated to the same applications. It depends on the system's needs, which of the protocol is preferred. NTP is the choice for all applications, for which a synchronization accuracy in the range of Milliseconds is sufficient. For those applications, NTP is the simple...
