To evaluate the platinum resistance sensors (750-461, 750-461/000-003 and
750-461/000-006) the measured values of the resistance are converted and
sent as temperature values.
All temperature values are represented in a standard numeric format. The
possible numerical range matches the defined temperature range of the Pt
sensors from -200 °C to +850 °C.
In the Pt 100 or Pt 1000 setting, the temperature values of the sensors are
represented with a resolution of 1 digit per 0.1 °C within a word (16 bits).
Thus, 0 °C corresponds to the numeric value 0x0000 and 100 °C to 0x03E8
(dec. 1000).
Temperature values below 0 °C are represented in two's complement binary
form.
The measured values of the resistance are directly sent by the 750-461/000-
200 (Pt 100) module.
