3.2 Considerations for SMV 3000 Transmitter, Continued
RTD requirements
Use a two-, three-, or four-wire platinum 100 ohm (Pt100) Resistance
Temperature Detector with rated measurement range limits of –200 to
450 °C (–328 to 842 °F) per DIN 43760 standard (α = 0.00385 Ω/Ω/°C)
as the input source for the process temperature PV.
Thermocouple
requirements
Use one of the thermocouple types listed in Table 4 as the input source for
the process temperature.
