Using constant current control for metal purification
In the vast world of power supply applications, we can identify two main categories for regulating the power applied to the load. The first is ‘constant voltage’, where the control loop maintains a constant voltage to varying load current demands; the second is ‘constant current’ where the current is maintained constant to vary the voltage applied to the load. Giacomo Mazzullo of TDK-Lambda explains.
Selecting a laser welding system with confidence
Purchasing a laser welding system for the first time may seem a daunting task to the uninitiated. How do you know that you are talking to the right companies? Do they have the best system for your application? Happily, the process of selection can be simplified and decisions made with confidence, by considering the points below
Embedded virtualisation and security for industrial automation
Industrial controllers and HMIs seldom have protection for the IT and network security. This article explains how virtualisation could provide cyber-security for industrial automation, especially where embedded controllers are used.
Capacitance modules are an easy route to energy efficiency
Andrew Davies of Bosch Rexroth explains how capacitance modules can be an easy and cost-effective way to improve the energy efficiency of machines.
Guide to selecting the optimum shaft coupling
There are many kinds of flexible shaft couplings, and while they all fulfil their primary purpose, each has certain characteristics that make it more effective in one application than another.
A guide to selecting non-contact sensors
Nowhere is the trend towards non-contact sensing more evident than in position measurement. With such a bewildering array of options, it can be difficult to select the most appropriate instrument for a specific application.
Angle sensors: do you know your arc-seconds from your gradians?
Angle sensors are generally rated and, just as importantly, priced according to their measurement performance. But performance is stated in a variety of ways and some manufacturers confuse matters by using crafty ‘spec-manship’. Mark Howard of Zettlex explains some of the terminology and provides an explanation of how to specify an angle sensor that is right for your application.
