Carburetor Diaphragm Movement Detector and its system

[tonyfoale]

chy,
What I was referring to was a linear variable differential transformer. Sorry for the confusion and the nomenclature. I like what you have done.

Owen,

I think that Chy's sensor could more accurately be considered analogous to an old style magnetic telephone ear piece or microphone.

Good morning Owen, thank you for your comment. It seems like it is, but I did no know this word LVDT though, lol.

Good evening Owen, many thanks. I looked for some informative site on this tool, and got it means. LVDT Seems it gives us geometry data of the linear movement of the core inside the coil housing, whereas this detector tells the axial movement of inductive material outside of this unit of coils when both of the material and the coils sit in the same axis. Thanks again,
Chy

Using this detector, I tried to see how the weight of metering plate means to the movement of it in operation. I thought some comparison could mean something about them.

This is one of the original diaphragm with a perfect round metering plate on it. Some holes are cut out there. It seems that these holes help to decease its weight a little, but it also seems to me that opening holes is not the least thing to do for this part. Later I got to know how it concerns to the movement.

This weighs 0.73gs, thickness is 0.2mm.

First I had and assumption that the weight of metering plate means more for higher spin speed, since they have to repeat ups and downs so many times in a second, lol. This thought of mine lead me to try out another homemade metering plate that weighs lighter than the original.

This weights 0.63gs, 0.10gs lighter than the original.

This homemade one was made from a piece of alu plate. Thickness decreased to 0.15mm by mallet work, was 0.3mm originally. Why mallet work? Yes I wanted to give this plate some hardening cause it vibrates with some pressure.


The weight of this plate itself was only 0.12gs.


(to be continued...)

Thanks for the response, chy,
While we are on the subject of diaphragm carburetors; do any of you fellows know of a source in the US where one could buy diaphragm material of various thickness's and compounds?

Good evening Owen, very sorry to say that I do not know much about the original manufacturer of my membrane. I got this from a local distributor who said this one is a US made but did not tell me who.
Regret that I can not be of any help to you on this. Hope you can find a better information.

Chy


p.s. Please let me informed of the information if you got to know some maker or distributors there. thanks in ahead.
