Thermocouple Disconnects

Thermocouple Disconnects

Thermocouple Disconnects

(OP)
I have an application that requires 40 type K thermocouples to be quick disconnected for equipment maintenance.  I want to use four 24 pin connectors and box receptacles with gold pins and sockets.  The type K thermocouple wire will be on both sides of the connection (Chromega+,Alomega-).  As long as each pair of gold pins remain equal in themperature I should have offsetting junction voltages, and therefore no error in signal.  I would appreciate a thought check on this, is it typical?  Thanks in advance.

RE: Thermocouple Disconnects

That may work for a while but what about corrosion? Will the gold contacts corrode over time? Or are these sealed connections?

RE: Thermocouple Disconnects

I agree with your statement: "As long as each pair of gold pins remain equal in themperature I should have offsetting junction voltages, and therefore no error in signal."

Functionality and expense are the main issues here. I am using sealed connections to minimize galvanic corrosion at the junctions.  I believe the $1/gold pin vs. $25/TC pin justifies this approach.  I appreciate your responses.

RE: Thermocouple Disconnects

Hi, this king of arrange ment was common in temerature controllers, the main problem is joining the thermocouple wires to the pins as you can't solder them.

RE: Thermocouple Disconnects

MJK, maybe I misread it, but the price looks closer to $2/2-pin connector.
