Elesa has updated its MBT series of knurled knobs with a new diamond-cut design, enabling the fine operation of machines, instruments and similar, in sizes from large (70mm in diameter) down to small (31mm in diameter).
‘The concept of green is a marketing invention.’ This statement more or less embodies a widespread belief that marketing is solely capable of creating or inventing necessities that do not exist. So how can such an empty concept persist for so long, mobilising governments, manufacturers and consumers? The aim of this white paper from Socomec is to clarify the environmental impacts of high-availability architectures, illustrating the basic concepts.
This application note from AP Technologies looks at how a change in junction temperature can affect peak wavelength, forward voltage and power output.
With the PMCprotego D (D.48/D.72), the highest safety level (PLe/SIL3) can also be achieved for the STO function without an additional safety card (PMCprotego S1) if the shutdown paths of the PMCprotego D are tested by an external device (for example, safety control). This application note from Pilz Automation shows in principle the procedure for such a test.
It has been recognised in every country that economic growth is heavily dependent upon the reliable delivery of electricity to the customer, whether that is a bulk industrial, commercial or residential customer. Further, efficiently using every source of generation including ‘green’ sources has become a mandate of many countries. This white paper from Omicron discusses the developments in the field of medium-voltage distribution equipment and the implementation of new technologies that ...
LEDs, like all diodes, are current-driven devices. The light output is directly proportional to the input current provided.
Bi-cell and quadrant silicon detectors are used for nulling, centring or measuring small positional changes in a light beam. As shown in this note from AP Technologies, bi-cells and quadrants are photo detectors with either two or four separate active areas respectively.
Dielectric response analysis is an advanced technique, providing information about the insulation condition of the measured test object. It is typically used for power transformers, where the water content in the solid cellulosic insulation can be assessed. The condition assessment of the insulation system of instrument transformers has not played an important role until now as typical measurement methods that might be used for power transformers are not applicable here. This paper ...
