Well, here we are, 2021 is here. Let’s show the shop as it stands in 2021. This is of course only the machining side but in another 10 years the pic will be of interest to people who like this kind of stuff. Also, been here for over 10 years now. wow.
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. here
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.
