Dwyer Instruments A3020 Photohelic Pressure Switch Gage

Dwyer Instruments A3020 Photohelic Pressure Switch Gage is a Series 3000 device that combines a pressure gauge with an integrated electrical switch. The A3020 model provides a clear pressure reading while also delivering switch action at a defined pressure point, enabling straightforward process monitoring and automated control. As part of the Series 3000 family, this instrument offers a compact, all-in-one solution for environments that require both a visual pressure indication and a threshold-triggered electrical output. Typical uses include alerting or controlling equipment when process pressure reaches the set point, helping regulate flow and containment in industrial applications.
