Modded out water distiller.
I could have just left it with addition of the RTD/PT100 sensor, but I wanted the 115C/239F cutoff (the one you have to push the ON button to reset) out of the circuit so I can take the temperature higher for decarbing or whatever, and I needed to mount the sensor connector, so I stripped it to bare bones leaving the 150C/302F cutoff in place for safety along with the aluminum strip with a couple of screws in the end that keeps the outer shell from rotating, which might pull at the wiring.
I used the sensor with the PTFE cable. The three PTFE insulated wires are wrapped in a sheath of PTFE, then braided stainless steel, and then an outer coat of PTFE. If I hadn’t played with electrical/electronics since a child with years of factory floor electro-mech assembly experience, I would have given up on the connector wiring. If you get down to the individual wires successfully, and you discover your nifty wire stripper isn’t delicate enough and/or able to get in tight, go old school, lay the wire out on a hard flat surface, and scrape the insolation away with a knife held almost horizontal, first one side then the other, I lost not a single strand. 15 watt conical tip soldering iron, vise to hold the connector, lamp up close, plenty of flux, pin 2 is the white - 1 & 3 red, good luck!!! I cut a piece with my Dremel tool from a round Tupperware container for the mounting plate.
Introduction to RTD/PT (Resistance Temperature Detection) sensors:
The sensor in epoxied in place with the Original J-B weld. good to 550F.
I’m waiting for the epoxy to fully cure before giving it a working test (the individual components have already tested out.)
On to the controller instruction manual!!
