Interfacing to an existing Type K Thermocouple

[pixelsitter]

Hello,

I don't have a lot of experience with Analog design and I have a project where I need to tap on to an existing type k thermocouple. This thermocouple is currently connected to another instrument.

Without affecting the current instrument, I need to feed this thermocouple to max31855 (thermocouple-to-digital converter ic).

What sort of problems do you foresee and what can I do so that the old instrument remains happy and I can share the same thermocouple?

Thanks in advance.
