This high-quality Duct Pressure Transducer is an essential component for maintaining the safety and efficiency of residential and commercial HVAC systems. Functioning as a precise air proving switch, this part monitors the differential pressure within the ductwork to ensure that the system is achieving proper airflow before allowing the heating or cooling cycles to proceed. By converting physical air pressure into an electrical signal for the control board, it prevents the unit from operating under unsafe conditions, such as a failed blower motor or a blocked vent. If your HVAC system is experiencing intermittent shutdowns or displaying airflow-related error codes, replacing a faulty pressure sensor can restore reliable performance. This transducer is engineered for durability and high-precision sensing in various air handling and ventilation applications.
Type: HVAC Air Pressure Transducer
