Cleveland Controls NS2-0221-00 Air Flow Pressure Sensor

The Cleveland Controls NS2-0221-00 Air Flow Pressure Sensor is a compact sensing module used to measure and monitor air pressure changes in airflow circuits. In HVAC systems, it is commonly applied in air handling units, furnaces, and ventilation assemblies to detect pressure variations across filters, blowers, or ducts and relay signals to the control circuit for proper system response. It operates as part of the airflow monitoring setup, the control board verify safe and consistent air movement. Positioned within the duct or blower section, it supports accurate pressure detection for coordinated equipment control in residential and commercial installations.
