Designing an Engine Oil Temperature Display Gauge Project

[Bazbro_imp]

I got my dip stick style temperature "DOREMI" from "Samurider"

Part # 96102 (Doremi Collection)

Note: Not accurate since the sensor does not contact the oil.

It is made for CB1100

It replaces the filler cap.

Could a metal wire be added/welded/soldered to the end, that then dips into the oil and transfers the temperature properly?

Interesting. If careful in length, it could be a reasonable consideration.

You'd only need it to accurately transfer the current temperature of the oil - no "measuring" involved, just put the temperature of the oil at the tip of the gauge, so I guess a small chunk of metal to extend the tip of the gauge down into the oil, securely attached to the tip would do it. I think a clamp would be best... welding or soldering could destroy the element of the gauge, as would drilling it for a rivet, etc., I guess? A tiny clamp, backed by some JBWeld, maybe?

RE clamp: Like a "metal crimp" device?

That's right, depending on how the gauge works.
Damaging it by crushing is one danger; having the extra bit 'fall off' is another. And not having it transfer the heat well is another. All solvable, but all critical, for such a simple addition!

Sorry for late reply on this subject as I did not subscribe to this thread.
Saw it only today (Nov 4th 2019).
As previously mentioned, on purpose, the thermistor does not contact the fluid due to the rotating clutch basket and the fluid level is much lower (as per sight glass).
I guess DOREMI does not want to take a chance of getting the tip too close to the rotating components.
I would not suggest to put anything/thermistor through that filler cap as there are too many rotating parts behind the clutch cover.
Attached is the thermometer picture taken when I was stuck in mild downtown traffic -This time the needle did not get into the RED zone.
It is only reading the ambient air inside the clutch cover above the fluid.
My best guess; there is around a 15 degrees difference in the gauge needle.

Next year, as a pet project, I will calibrate the DOREMI temp sensor against the EOT (Engine Oil Temperature/voltage) and will keep all posted.

... and indicated elsewhere, Csory has made significant related progress here:

That sounds great! I am very interested in the outcome.

Thanks GO,
I did monitor Csory progress on his project and is waiting for the final outcome.
Discussed the Engine temperature output from the EOT sensor from one of my threads.
That's the only item that I wish to add to my bike ... for now.

Csory has outstanding orders. He also has a pretty mature version of the User's Manual. Consider PM'ing him to get the *latest* official version of it to gain further insight.
