etector Pt1000·(Ro = 1000 ohms at
0°C), providing thermal protection for the servomotor. Provides great
linearity, speed and a temperature range between -200°C/-328°F and
+850°C/1562°F. Its use is recommended in control and measurement
systems. It has no polarity.
The following figure shows the resistance of the sensor as a function of
the ambient temperature (average values):
