I am trying to connect a combined pressure transducer and temperature indicator to a DAQ system by Dewesoft and this sensor has two available wiring configurations available, 3 wire and 4 wire. I'm unable to understand the difference between these two according to its circuit diagram and what is the significance of each.
Which configuration would be more suitable if I want to reduce the number of output channels from the sensor to the DAQ, or will the number of outputs remain the same despite its configuration.
(Link to the sensor spec sheet: https://www.pmc1.com/Customer-Content/www/Products/Files/ATM.1st.T.705a.pdf)
This is similar to another question that I have previously asked, but in this question, I want to figure out how the wiring actually works. Thanks!
