I have two pressure sensor attached to AD2174-4, similar to Figure 131 (Datasheet)

The sensor has build-in RTD1000 (within one sensor), can I replace thermister in Figure 131 with RTD1000?

Unlike AD7794, the number of pins is more limited in AD2184-8, ie no available 5 pin needed as in Figure 130. 

What equation to use to calculate Ohmic or Temperature based on ADC raw data?

BTW: Is there useful calculator tools (website) to illustrate measurement error based on 2,3,4 wire to RTD1000 (Bridge is 4 wire).
