Here are some web pages of connectors that can be purchased that maintain the thermocouple metals through the junction, so you can plug in or change on one side of the firewall, and not have to reconnect to Tracy's EM-2.

If you prefer barrier strips (screw connections) here is the link

There exist terminal blocks for thermocouples that are fabricated with the metals used in the thermocouple.

while there should be no issue in using this for the P2 connector it isn't really all that necessary as those points are for fixed sensors that won't be moved. P1 is where it would be really handy, as some of those 8 T/C's will be moved to various locations for various tests and running T/C extension wire back to the EMU will be somewhat of a pain.

Hi Todd,

I concur with everything you said. I also wanted the terminal block for the T/C inputs, but realized in talking to Tracy that it would probably introduce too much error.

What I did instead, was solder 4- 8 foot long sections of T/C wire from the P1 connector on the bench. I used the smallest, stranded wire I could get, but it still sucked. The ends of these pairs are twisted tightly, and soldered to make a probe (Tracy's idea, and it works). These are long enough to reach anything I might need to test, and coil up into about a 5" diameter coil when not in use.
