Posted in thread: Is a thermowell necessary? on 06-08-2013 at 07:04 AM
The sensor in your link is already sitting in a thermowell. The SS sheathing of the probe is
the thermowell, the sensor is inside.Empty thermowells can be used when you have a "bare"
sensor, or a sens...

I have one that has a 4.5m long, 8mm OD copper coil, 2kw element. It has a PT-100 on the wort
out and is put into a stainless thermos. PID controlled and keeps mash temp within 0.1-0.2 degr
C.It has l...

Just to clarify, the light and element needs to be in paralel not in series, if that was your
inension. One end to SSR and the other end to your neutral leg. For both the lamp and element.

Protto, based on what you're saying the voltage being provided is at a low current? If the
indicator light is on (which it is all the time right now, just gets brighter when the ssr is

Assuming your element is in series with your active light.The SSR is not a physical switch as
your symbol might indicate and even in an off state it has a small leakage current that will
give a readab...

Well maybe not a datasheet but it provides some info: made the assumption that the input was
resistive. Ether way you'll need a current source 4-20mA that can source 6v.Mabe you could use
a step-up ...

It says in the datasheet input should drop 6v at 20mA at max power. Input resistance should
then be:6v/0.02A=300Ohms.It should just turn on at 4mA. i.e. 0.004Ax300Ohm=1.2v50% power

I like your build, good job. I will be making a similar setup using the 44qt pot some day.About
the pump issue: When pumping liquid at or near boiling, the little underpressure at pump input
Posted in thread: 7/8" Kettle Plug on 03-04-2013 at 05:51 PM
The plug in your link will fit. 1/2" NPT does not actually measure 1/2" on the outside
diameter, 7/8" is spot on for 1/2" NPT fittings. As wierd as it may sound...

Since you'r a programmer, could you put in a function that disables the effekt of I if the temp
is, lets say 5 deg off set point, and only comes into effekt when your temp is within 5 deg.
That way yo...
