EP3204: Pt100 (RTD)

The advantage of four-wire technique is that the error resulting from the cable and contacts is included in the
measurement and cancelled out. In the 3-wire technique, the line resistance to the resistance sensor is
measured in one direction only, and is multiplied by two. This requires the outward and return lines to have
approximately the same ohmic resistance. An error is present in the two-wire technique; temperature
differences and cable cross-sections can make this error vary considerably.

Supply voltage

U

S

 - supplies the electronics for the fieldbus and for the sensor. It is electrically isolated from U

P

.

U

P

 - Is not required for the function of the module, and does not have to be fed in.

NOTE

Redirection of the supply voltages

If you use UP to pass the power on, and you connect a module in which US and UP are not electrically iso-
lated (e.g. any digital module) then the electrical isolation is removed by the downstream connection.
