PT100 RTD sensor

Post by ArriFerrari »

I recently purchased the Light object PT100 RTD sensor and I'm not sure how to wire it into my setup.

http://www.lightobject.com/Water-resist ... -P592.aspx

The diagram I'm given was meant for a 4-wire RTD sensor, but this one is a 3-wire. Could someone tell me how to hook it up?

Here's the typical application diagram:

In the software I can only say "No rotation" for the three wire. But I can say either "Sharing" or "No Sharing". Does that have something to do with the 2K resistor?

What is the RTD excitation current? The default is set to 5uA.

So you know what I'm looking at, here's the screen:
