Description
The Siemens Building Technology QAA2235.EWSN NTC sensor is a thermal monitoring component to measure and transmit accurate heat-level readings using a 100k Ohm negative temperature coefficient element. It is commonly applied in air handling units, room control assemblies, and climate management equipment within commercial HVAC systems where precise climate regulation is required for automated control operation. The sensor detects thermal variations and relays corresponding resistance values to compatible controllers for regulating heating or cooling operation. Its sensing capability supports stable conditional control, responsive system adjustment, and consistent operational accuracy across connected equipment.
