How to connect the RTD connection on analog devices CN0359 to the PT1000 temperature sensor (as shown below) ?

The CN0359 can be connected to either 2, 3 or 4 wire sensors.  The manual details the connections for each situation.

While it is not an optimum method, it looks like you will need to make or purchase a wire to BNC cable.  With a PT1000 the extra resistance will not hurt the accuracy as much as with a PT100.  You can do some compensation via the software.  If you are concerned about accuracy you need to change to a 3 or 4 wire sensor.

I have two CN0359's and installed them in a case with banana jacks for my four wire sensors.
