(1) Digits following the RTD type represent the temperature coefficient of resistance (α) , which is defined as the resistance change per ohm per °C. For instance,
platinum 385 refers to a platinum RTD with α = 0.00385 ohm/ohm -°C, or simply 0.00385/°C.
(2) Actual value at 0°C is 100
Ω per DIN standard.
