PID probe and BDS

[itchybeard]

Hi All.
Another question regarding the PID and the DBS. I have noticed a massive difference between the f reading on the PID cabinet
probe and the smoke generator reading ( can be 100^of or more)  I am assuming that the PID is the more accurate but it got me thinking where
is the best placement for the  PID cabinet probe?

• just above the top shelf
• just above the top layer of food in the cabinet regardless of which shelf its on
  

Cheers.

100 °F sounds excessive to me.  On my six-rack DBS the biggest difference I have seen is maybe 30-40 °F.  Typically, the Bradley thermistor will indicate higher during a strong heating period (like just after the smoker is loaded or during a preheat period) and then will equilibrate to a lower temp once things stabilize.  I sue an Auber Dual Probe PID and I hand the control probe right under the meat where I want control to be most accurate.  The temp will be noticeably lower above the meat, and if you have multiple racks loaded it will progressively drop as you go higher.  So long as you understand lower and beneath a loaded tray is hotter, you can choose your control point and temps for what you want to achieve.  I prefer to keep it at its hottest for control on the bottom side of the lowest loaded rack.

Thanks BuyLowSellHigh. Now I think about it it makes sense. I have moved the cabinet probe down underneath the first layer of food (Ribs) which is
the second shelf and I'm getting a more accurate reading now. Only about 15-20⁰f  difference now
I had a load of ribs in so as you rightly pointed out as I got higher the temperature dropped quite a lot.
This is my first real long smoke and I have learned a lot. Thanks  :)

I will post some pictures of my first go at the ribs. I followed the "How to make Pork Ribs in a Bradley" recipe. With a few additions of my own. Fingers crossed.


Cheers
