Dome temp vs. grate temp

Options
I'm sure this has been asked a thousand times, but I'm a new guy...how much a difference is there? Had my new LBGE three weeks now and have been trying a few cooks obviously and attempting to get dialed in. So far so good. Did a meatloaf tonight and turned out fantastic. Done a spatchcocked chicken, CSR's, and a few pizzas, all came out good. Looking at doing a brisket soon and wondered about the temp difference, if there even is one. Comments? Thanks guys..

    20-35 difference is what i am seeing... as a matter of fact, Its currently 27-28 degrees different.

    The dome is higher than the grate then? Appreciate the response.

    30 minutes after lighting the egg probably 30-35 degrees but the longer the cook the closer they get. This is based on a low and slow though higher temp cooks have higher variances.

    This has been my experience as well.

    So think about heat loss at the dome so far from the fire vs the closer grate. That may help you remember that the dome Is less then the grate

    I think you will see a difference if you are indirect cooking versus direct. Indirect the dome temp will be higher than your grate for some time. Direct cooking the opposite may occur.

    so i think the point of the story is to buy a maverick and check your grill and you wont regret it

    If direct, grate will typically be higher than dome due to distance from the fire. If indirect, dome is typically higher than grate as the heat flows up and around the stone/plate setter.  Although on long low and slows, the grate eventually comes pretty close to dome (at least for me).

    Just got my Maverick and have a question. If I use my AR, do I put the grate thermo on the highest part of the grill or further down closer to the felt line?

    Perfect explanation. The grid temp is higher than dome for direct cooks, grid is lower than dome for indirect cooks. Strongly suggest you do not use your Maverick for direct cooks, Burning lump directly under the probe will give you wildly changing temps and you will, IMHO, shorten the probe life.

    Thanks for all the responses, and they all make sense. I do have a Maverick so I will have to do a comparison on different type cooks. And Dredger, I would put the grate therm closest to where your food will sit.

    Related, by general convention, when temperatures are mentioned, unless otherwise stated, the temp is referring to dome temp as that is the one thermo all BGEs have.  And since we all cook to finish temp or some other parameter such as "bend" or "feel", the cooking environment temp is a guide to how hot the BGE is.  This info will help with an eggstimate as to when the cook should arrive at the finish-line. 

    I believe you can get too wrapped up with temperatures in the BGE as the internal environment has thermal gradients just like an oven.  Best to ensure your thermo(s) are calibrated and use that info to help manage the cook.  Just an opinion and we all know what those are worth.

    Thanks SmokinOutBack. That's what I thought. Just makes sense, but wanted to check with the eggsperts.
