The Dwyer Instruments 1627-5 Differential Pressure Switch monitors differential pressure from 0.5 to 6.0 in. wc and provides an electrical output when the sensed difference reaches its actuation point. It measures the pressure difference across two ports and is used to trigger controls or alarms in systems where maintaining a specific differential pressure is essential. Model 1627-5 is a compact differential pressure switch from Dwyer Instruments, with measurements expressed in inches of water column for precise airflow monitoring.
