A new optical interrogator, the MXFS, provides stability against external influences and a high-sensor capacity of 128 channels per device, making it a candidate for use among engineers carrying out measurements within unpredictable environments, such as construction sites or laboratories. MXFS is a fibre Bragg grating measurement device, based on the BraggMETER technology, that is […]
The challenge of testing obsolete PCBs
How to test and maintain obsolete systems when the relevant documentation is absent. Alan Lowne, Saelig Co. Inc. Obsolete PCBs or boards lacking circuit schematic diagrams present a conundrum when there’s a need for repair. Online searches for old datasheets may not be productive. What happens when obsolete boards must be fixed but there is […]

Ruggedized dc/dc converters help keep ocean water clean
Ruggedized power modules now play a role in minimizing the contamination of sea water from the world’s shipping industry. Axel Schütz, TRACO Power There are more than 90,000 ships of various types and sizes on the seven seas: Cargo and container ships, oil, gas and chemical tankers, ferries, tugboats and so forth. One aspect common […]
Low oil-bleed/specific-gravity gap filler pad material in sheets, custom shapes
Sarcon GR14B from Fujipoly is a low oil-bleed/specific-gravity gap filler pad material that is offered in sheets or custom shapes to fit your exact application. This material is a candidate for cost-sensitive, lower-power applications that do not require high conductivity. When placed between heat-generating components and a nearby heatsink, this 0.5mm thick, highly conformable gap […]
Grounding considerations for renewable power generation
It pays to know the difficulties that can arise when testing and evaluating ground systems for solar panel arrays and wind farms. Jeff Jowett, Megger Industrial wind turbines are typically 280 ft high and getting taller. Their height makes them prime targets for lightning strokes that peak in less than 10 µsec while producing tens […]
