What kind of sandwich adapter ..(remind me) and what's it doing there??
Between the slices of bread. The olive oil should be room temp........

just an adapter w/ 4 - 1/8" NPT outputs. not currently in place, i just wanted to put a oil temp guage on my grand cherokee and have it laying around...no remote filter, preoiler, or cooler. guess i could rig somin up, put a T fitting where oil pressure sending unit is??
but 1st ? is this a good location for the sending unit in the first place?

It's the most functional for your needs. Some of the racer types in some Asian engines like to tap off of some other location, but you need to have a constantly refreshed flow ..which is what you'll get at that spacer tap. You'll read sump temp.

Temperature Sending unit goes in the pan

I have it in the pan on my 91 BMW 318I. I have noticed that there, my oil temperature never goes over 170, even in the heat of summer, under hard driving with the AC on.
A far cry from the 200+ that folks claim. I dont know if this is becaue of the sump and pan cooling fin design, or because of another reason... Id likely tru to put it into an active flow of some sort... Oil pressure sender?

The sender port wouldn't necessarily be a poor choice, but you can't tee into it. It needs a dynamic flow across it. I guess if you were feeding a bypass filter ... It's a dead head if you tee the sender. It won't conduct enough heat to the temp sender. You'll be far more subject to under hood temps.
Hi,
most oil temperature readings are taken from the pan - this is the "bulk oil" temperature - the one that matters most
If reading from other locations there will be little chance of being able to compare results. In many engines I have seen local oil temps up to 160C - but the bulk oil temperature was around 95C. This is very typical!

The flow by the filter on most engines is merely detoured through the pump, Doug. I don't see the major alteration. Now on the trans, I tend to go with the pan and call it "insult reserve" since we're typically on a time weighted average on ATF fluid life.
That's not disagreeing with you

I'm running temp and pressure off a paralell port for in/out before the cooler. The remote oil filter has these.

When I added temp readings, I had to swap the position of the filter and the block adapter. I moved one of the pressure taps to the dead end ports and had to have the temp sender see the incoming stream on the way to the filter. I was lazy at first and just threw a sender in the vacant taps at the end. The result was lots of influence from underhood heat soak. It would, more or less stabilize while in motion ..and the reading were about the same, but the reactive nature of it was radically different. In the preferred location you would see the immediate retreat of the oil temp when you let off the gas pedal at highway speeds. Just as soon as the combustion process wasn't there to maintain the oil temp. You would also see the change in rate as you approached equilibrium.
Not elegant ..but it worked in a "plug and play" manner.

I had to mount mine on the frame rail hence no heat soak. There's room in the engine compartment if you relocate the battery or the engine. lol
Chris142 said it short and sweet, and correctly.
but not practical.

Exactly. It's fine for those who come OEM with the things. Hollow drain bolts aren't plentiful. Greddy sells plenty of metric offerings.
..and ..by the time you're done, the tap on a spacer at the oil filter is just fine. It's typically the last stop before the main oil gallery ..and the rest of the engine. 100% of the flow passes that point. This is different than some of the Asian racer types that prefer to grab some isolated leg that gets the flow to the cam (or whatever).
