Dwyer Instruments DH series differential pressure controllers 3 in 1 featuring a digital display gauge, control relay switches, and a transmitter with current output. DH controllers are ideal for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy. The selection of pressure, velocity or volumetric flow operation is available in several commonly used engineering units. Two SPDT control relays with adjustable dead bands are provided along with a scalable 4 mA to 20 mA process output. Programming is easy using the menu key to access five simplified menus.
