SDB-Tn10 - Duct Mounted


Passive temperature sensor for duct mounting with cable gland for Vector Controls NTC-type inputs

The SDB-T measures temperature by use of a NTC sensing element. The sensing element is a glass packed thermistor with a negative temperature coefficient. Its resistance changes according to the temperature. The change follows a specified curve.


  • On return air ducts to measure room temperatures
  • On supply air ducts to measure heating/cooling supply air
  • In heat exchangers and air handling units to control heating/cooling coils
  • As frost protection sensor


  • Thermistor sensing element for Vector Controls NTC-type inputs
  • Simple and secure installation
  • Compact size and modern design
