Thermal sensor connection is organized via two-wire cord. The sensor itself is a thermistor; basically it is a simple resistor and its resistance changes depending on the temperature. TFF-103 thermistors are used.

TTF-103

TTF-103 specification:

  • Negative temperature coefficient (NTC)
  • Operating range: от -40°C до +100°C
  • Resistance at 25°C: 10 kOm
  • Accuracy: ±5% at 25°C
