If the sensor type is SPRT, the adjustable parameters
are Rtp, a, b, c, a4 and b4. The details of these parameter
definitions can be found from the ITS-90.
As an example, calibration agencies provide following
parameters after SPRT is calibrated:
Rtp: probe’s resistance at triple point of water.
a4 and b4
：
low temperature range parameters.
a, b and c
：
high temperature range parameters (b and c can be
“0” for some instances. (Please refer to ITS-90 for more
information.)
If the sensor type is IPRT, the adjustable parameters are R0, A,
B and C:

The details of the parameter definitions can be found from the
industrial platinum resistance thermometer calibration
procedure.
As an example, calibration agencies provide following
parameters after IPRT is calibrated:
R0: the probe’s resistance at 0°C.
A and B: the temperature coefficients at temperature range
above 0°C.
C: the temperature coefficient at the temperature range below
0°C.
