11.4 Temperature Conversion Characteristic
Since RTD sensor has non-linear characteristic, RTD input module executes linearization per each
section.
The graph below is an example to describe the linearization process and is different with graph about
actual sensor temperature input.
(1) PT100: JIS1604-1997
(2) JPT100: JIS C1604-1981, KS C1603-1991
Non-linear characteristics: The resistance-temperature characteristics for RTD sensor are presented
with table (JIS C1604-1997). This characteristics table displays resistance value of the sensor to
temperature, namely, the change of the resistance value per increment of 1
℃
. When the
temperature is changed by 1
℃
, the change of resistance is not in constant width but in different
width per section, which is called the non-linear characteristics.
