Temperature Acquisition through an Intrinsic Safety Barrier

I would like to acquire traceable data from a Type K Thermocouple through an Intrinsic Safety Barrier.

What affect will an Intrinsic Safety Barrier have on the measurement quality of a Thermocouple?

If you have experience with this, please reply.

It should have no effect if you go with a Zenner type barrier. It will add a few Ohms of series resistance but provided your measuring device is high impedance it should be OK.
