The Data Formats for RTD Temperature Ranges for 0.5 and 2.0
mA Excitation Current table shows the temperature ranges of
several 1746-NR4 RTDs. The table applies to both 0.5 and 2.0
mA excitation currents. The temperature ranges of the remaining
RTD units vary with excitation current, for example, 1000
Ω
Platinum 385 (table Data Format for 1000
Ω Platinum RTD
(385)), 1000
Ω Platinum 3916 (table Data Format for 1000 Ω
Platinum RTD (3916)) and 10
Ω Copper 426 (table Data Format
for 10
Ω Copper 426 RTD).
