In-Process Stormer Viscometer – Damn near complete

  The viscometer is nearing full completion! YAY! To mark this occasion to mark the end of a long two years, I am placing a small gallery of the almost finished product. The only thing missing is the outside cover which consists of a 4″ od aluminum tube. Also, the springs I’ve ordered have also not arrived as yet, however, for now, the elastics will suffice. Here are some of the features and facts:
 

  • Can be used in-lab or in-process
  • Selectable RPM with a tight tolerance on RPM +/-0.5RPM
  • User calibration routines. This allows the end user to calibrate with 3 fluids of known viscosity
  • 16 key keypad, used for calibration and settings, also for running special tests
  • Can be used as a laboratory gel-timer
  • Can be used for custom tests besides stormer viscometry
  • Low power consumption <100ma or <2.4W
  • RS-485 Serial output
  • Control electronics have complete galvanic isolation
  • 24VDC supply required
  • repeatability (requires further testing) +/- 1.5%
  • Modbus protocol (not yet implemented)
       
      Here’s the Gallery!

       
       Yes, a few too many pictures, oh well.
       
       This thing took me quite a while and what I learned from it was immeasurable. Thankfully now that everything works as expected I can focus on my other projects without having this thing hanging over my head. Here’s to completion!
       
      As an aside, here’s an interesting document on viscosity.

Playing with the Gallery

Well, I’ve been thinking about deleting the gallery that’s been installed since I started this site. So far I haven’t even paid any attention to it since it recieves very little traffic and frankly, I don’t pay any attention to it.

I was thinking about deleting it… Instead, I’ve decided it’d be better to revive it, keep all the images that are on there and use it as a backup for all of my raw images. I’ll keep anything sacred close to the chest but other than that, I’m gonna make it public.

So, http://smackaay.com/gallery/

I’m going to start uploading sets of images, slowly but surely, as to avoid bandwidth charges!
