Dwyer Instruments DHII-008 Differential Pressure Controller 25.00"WC

The Dwyer Instruments DHII-008 Differential Pressure Controller measures and regulates pressure differences up to 25.00 inches of water column for controlled system operation. It is used to control pressure in systems like air handling units and cleanroom ventilation systems in HVAC systems, to enable the airflow to be balanced and controlled. It is attached at specific sensing points connected to duct or system lines. It operates by detecting the difference between two pressure points and modulating signals to achieve the desired setpoint.
