It goes without saying, you’ve got to use the correct parts for the job..


Re: Firewall electric thru connections

Every turbine that I have worked on had cannon plugs or types of and they ALL  had special specific pins for the thermocouple ie allumel and chromel. I know of several instances where incorrect pins were used some worked and one caused a meltdown during start due to the computer not seeing the correct temperature.
Just be sure of what you are doing.

Doesn’t everyone know what a canon plug connector is? The thermocouple wires are connected via a cannon plug on every turbine I’ve had along with the tach generator, temp sensor, frag’s etc.. 

You can pick these up used at an aircraft supply place like ET Supply in LA. as well as many other supply places.

I think that is what Corbin showed a picture of and the MIL spec part number for. Am I wrong?

wink_smile Ha!  Nope!  All of this came about because Imraan and I were discussing this topic.  Now you know that I was asking for Imraan (although he wasn't really interested) because he didn't want to have all of the opinions show up.  I let him know everyone has opinions just like belly buttons and he didn't want to see the belly buttons.  So here we are....I am not skeered o' belly buttons.  We did get it hashed out tho' didn't we?  Not sure if Imraan is watching but if he is show him your's.  teeth_smile

Then that instrument is essentially a voltage meter (with a selector switch), that is calibrated to directly read in Degrees/Temperature, the voltage output of the EGT or CHT probe metals’ hot junction (either J or K type thermocouples).  Are you looking to put in a different instrument to read those temps?

I suppose it is free standing?  It is fairly old but has a toggle switching between egt/cht and each probe has two designated wires going all the way from the head to the probe.

Re: Firewall electric thru connections

For those who are using connectors not if thermocouple material: a difference in temperature on the two sides of the connection will induce an error.  It will be equal on each sensor so for EGT the error is harmless.
The thermocouple effect on this connector is much smaller than for a junction of the two thermocouple metals.  My tests at heating each side if the connection separately with hot air (hotter than engine compartment) showed a couple degrees of error, not enough to worry about.
With CHT we are concerned about red line and a couple degrees might be significant.  The error will be equal for all CHT channels so comparing cylinder temps will remain valid.

Re: Firewall electric thru connections

Jay, that was just the point I was going to make. Any connections between thermocouple and instrument need to be same material or you will get a "Cold Junction".  That can change the actual temperature shown by a fair margin.

Also its is all very well going for the heavy option of connectors on your firewall, make sure you do your safety analysis, i.e. if it happens to become disconnected what effect will it have on your flight.  Does it have ratchet locking or do you need to wire lock.

Being an old Aircraft Electrician, I have gone for the lighter, cheaper option of wired direct, but then my MGL RDAC is firewall fwd anyway, so that reduces the cables through the wall.

Hi Bruce,

 

Just a note concerning the EGT and CHT thermocouples passing through the firewall. I originally planned to run the EGT and CHT connections through the large connector that Corbin showed (same as mine). I nixed this idea after reading Bob Nuckols articles. He noted that it is possible to break the thermocouple wire and insert a connector of different metal, but if one side of the junction is hotter or cooler than the other side of the junction (like going through the firewall), this temperature difference across the junction will distort the temperature that the instrument reads. I avoided this issue by using male and female plugs at the firewall that are constructed of the same metals as the thermocouple, so essentially there is no junction. Let me know if you want to use some of these connectors and I will send you the details. They are not fireproof, but they are laboratory quality, so I felt comfortable using them.

 

Cheers,

Jay

Bruce do a search for bulkhead connector sub-d 

That will get you multiple sources. The soldered ends aren't as common in aerospace use as soldering is seen as less reliable but can still be found as std or a milspec item

It seems like Justin Mace had a connection for multiple wiring bundle with a screw off quick disconnect that went thru the firewall.  It was fireproof and soldered on the inside with barbs like molex connectors on a sub-d.  It seemed old school perhaps WWII.  Does anyone have any intel of where and what to buy?  Would be nice to have screw connections for wiring firewall forward for solid connections.  Anyone, anyone, Buehler?
