This Navien component is an air pressure sensor designed to monitor and regulate the pressure of air within a specific system. The sensor operates by detecting changes in the air pressure and converting this physical quantity into an electrical signal, which can then be interpreted by the system's control unit. This allows for real-time adjustments to be made, ensuring optimal performance and safety. The Navien air pressure sensor is typically used in heating, ventilation, and air conditioning (HVAC) systems, as well as in various industrial applications where precise control of air pressure is crucial. It is known for its accuracy, reliability, and durability under varying environmental conditions.
