2524Re: [Distillers] Control valve for Nixon-Stone ?
- Jun 10, 2001Hi Tony
Unfortunately there is not cheap and easy way of controling the still like
this in such heigh procision. For a incrament of .1 it is quite hard to find
temperature measuring instraments especially ones which will control
electronics. There are thermocouples which you mentioned (i think type K is
the best) they have temperature incraments of 1 degree. maybe someone else
knows of better instraments
i have yet to see solenoids which can finely control flow rates the only
ones i have seen are gate valves allthough i have seen the devices which
seem like they are designed to control solenoids that control flow rates
To turn off the still permanently you could fairly easily incorperate a
switch which would do what you want into the electronics of the control
system. i would guess you could get a switch like this at a electronics
At the moment i am working on a control system which will interface with a
computer so you can change the control of the still when you modify it as i
seem to always be doing. I am currently experimenting with ways to over come
the temperature incrament problem.
i hope this helped a little
