What is the purpose of a pressure sensor in a HVAC system?

The purpose of a pressure sensor in an HVAC system is to measure and monitor air pressure. Pressure sensors are crucial for ensuring that the HVAC system operates efficiently and effectively. They provide real-time data on the pressure levels within ducts and different system components, which helps in assessing whether the airflow is adequate for the system's performance. By continuously measuring and monitoring air pressure, these sensors enable the HVAC system to maintain optimal performance, adjust airflow as needed, and ensure that the heating or cooling processes are functioning correctly. This capability allows for better control and management of indoor climate and comfort levels in a building.

In contrast, monitoring temperature fluctuations, controlling humidity, and increasing airflow relate to other components and systems within HVAC functioning, but they do not directly pertain to the primary function of a pressure sensor, which is focused specifically on air pressure measurement.
