Depending on the alloy and purity of the platinum, the nominal temperature coefficient, α, may range from 0.00375 Ω/Ω/°C on the low end to 0.003927 Ω/Ω/°C for pure platinum. The current international standard for process control RTDs is 0.00385 Ω/Ω/°C, meaning the resistance of a "PT100" RTD is 100Ω at 0°C and 138.5Ω at 100°C:
Are sensors other than 0.00385 common?
