Johnson Controls P32AC-1 SPDT Differential Pressure Switch 0.15/12" Bracket

The Johnson Controls P32AC-1 SPDT Differential Pressure Switch is an essentialcomponent in HVAC systems intended for controlling and measuring differential air pressure. It has an (SPDT) type which enables it to switch electrical circuits depending on the pressure difference. With an adjustable differential type, it can achieve the exact pressure thresholds that are suitable for different HVAC applications. This switch is installed on HVAC systems to measure Airflow, to confirm that there is enough fresh air and safety as well. They detect pressure variations at their input ports and control the activation or de-activation of circuits within the process.
