7.2 Pt100 Resistor Sensor
Pt100 resistor sensors are used with VSS in-vacuum and Cryo 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.
Rated resistance at 0 °C: R
0
= 100 +/– 0.04 
Resistance at 100 °C: R
100
= 138.5 +/– 0.1 
The resistance values for other temperatures can be found in the fundamental value tables
for Pt100 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.
For temperatures below –70 °C class B is valid.
