The figure below shows a connection example "RTD (0)" as reference junction with external
thermal resistor Pt1000:
①
M12 connector only at X1 circular socket
②
External Pt1000 (α = 0.003851) in the area of the reference junction with copper cables at
terminals 1 and 3. The comparison value of the external Pt1000 at circular socket X1 also
applies to thermocouples at X2, X3 and X4.
