Temperature probes

Temperatures will be controlled by a PID or proportional-integral-derivative controller.  The ones I'm using are Auber SYL-2352 PIDs.  The temperatures are monitored by the PIDs using a RTD or resistance temperature detector.  I am using Auber Liquid tight RTD sensor, 1.5 inch, 1/2 NPT Thread sensors.  I modified them slightly to be a bit more sturdy and to connect to my main control panel with XLR connectors.  Here is what I did....

Temp probe parts

I started with a length of 1/32in wire rope, 2 pieces of 1/8in braided sleeve, a 3 pin XLR connector, the RTD probe and some heatshrink tubing.

I loosened the clamp in the probe end and looped the wire rope through it.  This will help if the probe is ever accidentally tripped over or pulled.

I then pulled the black braided sleeve over the wire and then pulled another colored braided sleeve over that for 2 layers.  Each probe has a layer of black and then another color over that.  Then I tucked the ends of the sleeve under the clamp and tightened it down.

The end was then covered with 3 different sizes of heat shrink tubing.

On the control panel end, I put on a nylon tie wrap and then folded the wire rope over it and applied another tie wrap to secure it.  The wires were then soldered to the XLR connector and connector was then closed up.

Here is a picture of the finished probes.  One probe will go to each vessel and the other end will attach to the main control panel and inside will go to the PIDs.
