More than one controller for a PT100 3-wire element

I have this issue where I have a quit simple, but important heat control system. It's actually a very simple system - if one or more of the PT100 elements reaches a certain temperature, the cooling activates and run until a lower temperature is reached.
There is a request to find out if it is possible to monitor the temperature in real time at another location.

So - this request would be doable if I could just remove the old control element and phurcase a PT100 to modbus converter. However - it turns out the facility is assembled in such a way that the old control panel cannot just be removed like that.

So the problems/limitation for now is as following:

• The subject to be measured is assembled in such a way that it is impossible to just attach more PT elements (i.e sealed off).
• The old control panel have to stay put for the foreseeable future.
• New PT100 converter must use 24V supply voltage.

This is the solution - if it exist at all.
Due to practical company restriction - any solution must exist on marked today.

There must be a device that:

• Accept one PT100 censor, 3-wire (or several groups of PT100 converters).
• Two or more outputs - outputs must be isolated from supply voltage and use 3 terminals that resemble/simulates a PT100 element.
• The output values must be equal and also be equal to the input (i.e. make one PT100 element to be seen as two separate ones)

Or - maybe you folks see another solution that I'm not seeing here ?

So one issue for me - I don't know what an English term for such device should be named. It may exist already, but I'm not able to find a reliable search phrase.
