"Active" protection by CTP thermistor.
Maximum voltage delivered on open circuit: 1 V typ. / 4 V max.
For measurements lower than 10 nF, a shielded cable is recommended.
For a 2 wire-link, use very short wires (< 25 cm) and twist them .
In this position, you measure a temperature via a Pt 100 or Pt 1000 sensor.
