Description
The Johnson Controls P74EA-8C Differential Pressure Switch is an essential component of HVAC systems because it measures and regulates differential air pressures. It has a fast and accurate response to pressure changes due to the SPDT snap-acting mechanism. This accurately detects changes in pressure within ducts or chambers with a set 3.5 PSI differential and a pressure range of 2-26 PSI. For regulating ideal airflow, preventing over or under pressure systems and safeguarding against various harms that a system can embrace this switch is normally used in equipment of HVAC. The 36” capillary tube is convenient in installation since it can be placed in various HVAC systems. Its 1/4” flare nut connection ensures that it can be connected to normal HVAC fittings.
