The Honeywell DPS400A differential pressure switch with duct kit monitors pressure differences across a duct path and provides a switch output in response to the sensed differential pressure. It operates over a 40 to 400 Pa differential pressure range, giving a practical threshold for airflow or blockage detection in ducted systems. This package includes the DPS400A sensor alongside a duct kit for straightforward installation in-line with ductwork, enabling reliable pressure sensing in relevant applications.
