7.2 Pt100 and Pt1000
Pt100 and Pt1000 temperature sensors are used with space stepper motors in the tem-
perature range
–200 to +300 °C.
These precise sensors are used in extreme industrial and laboratory conditions. They con-
sist of a wound resistance wire that is mounted and supported inside a cylindrical ceramic
case.

The resistance values for other temperatures can be found in the fundamental value tables
for Pt100 / Pt1000 resistance sensors.
Accuracy class:
T = 1/3 of class B acc. to DIN EN 60751
In accuracy class T the valid scope is reduced to
–70 to +250 °C.
Class B is valid for temperatures below
–70 °C.
