UV sensor

Pimpom · 2020-08-03T07:36:30+00:00

I'd like to be able to determine the intensity of UV radiation from different sources like CCFLs, the sun under various conditions, UV torchlight, etc. The sensor doesn't have to be very linear, only approximately so. It's not necessary to measure the absolute intensity either - knowing the relative values is enough. Will a UV LED work? I don't have any with me, so I can't just try it out.

Hamamatsu still makes them.

Boilers also have that nasty hydrogen-embrittlement problem when run too hot, and of course the standard of maintenance in your average merchant ship is not exactly medical grade.

1200 psi steam is nasty, corrosive stuff. It would dissolve stainless steel, especially at pipe bends. Each engine room had a small chemistry lab to check the feedwater quality often.

The pipe joints were all welded. A weld could have a tiny pinhole defect. The way to find a leak was to wave a broomstick all around all the welded joints. A silent, invisible leak would cut the end off like a laser. It could cut your head off, too.

Maintenance issues killed steam in favor of diesel. The steam systems were just too complex.

A critical component of a steamship was the small independent take-home motor.
