Pretty sure the answer is no but I don't relish the thought of punching a 2nd hole in my brewpot right alongside the first!!

Unfortunately, no. But if your PID can read linear input signal, you can use a transmitter to covert RTD signal to linear signal like 4-20mA, then you can use two PID controllers to read the same linear signal at same time.

Hmmm. . . good idea.  Might be more trouble than it's worth but a good idea never the less.
