Which sensor is specifically designed to measure pressure in HVAC systems?

The differential pressure sensor is specifically designed to measure pressure differences in HVAC systems. It operates by comparing the pressure at two points, which is crucial for monitoring airflow, airflow resistance, and the performance of different components within an HVAC system. By measuring this pressure difference, the sensor can help maintain optimal system efficiency and ensure proper operation of equipment like fans, filters, and ducts.

While temperature sensors measure thermal conditions and humidity sensors assess moisture levels, they do not measure pressure, which is critical for understanding system dynamics. Capacitance sensors also do not have a direct role in measuring pressure. Thus, the differential pressure sensor is uniquely equipped for this purpose, making it essential for effective HVAC performance monitoring and control.
