Monitoring Dephleg Temperatures

[YHB]

I am about to order a couple of thermometers to monitor the water temperature of the dephlag on my new, albeit very slow, build.

Questions

Should I?


1) have a thermometer on the Output only.
or
2) have a thermometer on the Output and Input.
or
3) use an Arduino to display the difference between the Input and Output.

I am leaning towards 3) but is this me overthinking / overcomplicating once again?

I have had sucess with controlling a solenoid valve on the inlet via PID monitoring exit temp.

Does the input temperature of the water not affect the exit temperature?

I do not want to automate the control, just monitor and manually adjust.

The answer to that last question is a YES.

I bought a Digital K / J type thermocouple Thermometer from ebay that can display both temperatures or the difference between them. Highly recommended. The shop is sun mart electronics.

I am in the same boat as you in that I want manual control not automation (at this time) and I will be doing the same. Monitoring the input and output temperatures.

Thanks for the replys.

Myles your differential thermometer looks cool, but £30.00 is a bit more than I want to pay.

Thinking about it, the remnants of my Parrot build include a spare Arduino Uno and two Dallas sensors, so I think for the price of a new LCD I should be able to put something together.

Perhaps include an alarm to tell me if the output is hotter than it should be?
