I know it has been covered here, and if I google I get 3000+ posts but I still didn't find the answer to: where do you mount the sensor or probe of PID?

I want to install one on Silvia, the wiring seems simple enough etc, just that part is not clear to me...Is there a drawing or something somewhere?

Does anyone use one with 12V DC power supply? I see many with 110~240VAC...

TIA

It'll depend on the sensor/version of Silvia.  The older version I believe had a well, and you can get a screw type sensor.  The newer ones most people just put wherever they feel they get the most 'accurate' readings for their purposes -- I'd guess, most often its on the top near-ish the cold water inlet.  The Auber instructions suggest putting it where the old t-stat you're replacing was.  That's a 120V system.

Picture below, but it is tiny due to the file size constraints.

My PID came with an RTD with a screw hole lug. I plan to mount it to the boiler with one of the screws used to secure the present brew thermostat.  My PID also is low voltage. I can't remember if it is 12 volts or 24 volts. the rectifier is internal so it can be AC or DC. I still have not decided where I am going to mount my transformer.

Thanks.
My machine is V3 built in 2011.
What is an "RTD" with a screw hole plug?

The Auber instructions suggest putting it where the old t-stat you're replacing was.  That's a 120V system.

OK, that sounds reasonable, what threads are the thermostats on Silvia?

I found this, 12VDC Click Here (www.ebay.co.uk)
It takes 2 watts only@12VDC.

I am planning to run wires into Silvia from my Power Supply that plugs into a wall outlet. Meaning I don't want to mount the transformer inside Silvia...
cheers

RTD with screw is like this, M4x0.7

Click Here (www.auberins.com)

or non threaded

Click Here (www.auberins.com)

The 12 v PID will require a power supply and the 120-240v can tap inside the machine via the on-off mechanism.  No transformer or power supply for the 120 - 240v AC, and you are stepping down to 12 - 24v DC.  The are all very low watts.

Many of the ebay PIDs have less than clear instructions and some are difficult to understand which model you actually get.  Many of the ads are for several models.  Read on the auber site above and you can get an understanding of what you need.  For DIY the PID algorithm is for brew and the alarm can run steam.

The thread is below Gaggia, but similar concept and there is also some generic PID stuff.  Look up Tasseloff, we worked through Silvia install including supplies on the thread below and one of his threads.

Thank you, that's what I needed to know.
