Dwyer Photohelic A3000 differential pressure switchgauges combine the functions of a precise, stable and repeatable differential pressure switch with an easy-to-read analog differential pressure gauge. Based on the time-proven Magnehelic differential gauge technology, the Dwyer Photohelic A3000 series offers a non contact, stable measurement. Additionally, Fluidic stock several ranges and are able to offer calibration services.
Photohelic A3000 switch setting is easy to adjust with external knobs on the gauge face. Alternatively, to prevent unwanted switch adjustment, the Dwyer Photohelic A3000 switchgauge can be offered with tamperproof knobs (supplied with universal key). In the event of power failure etc, the Photohelic A3000 differential pressure gauge is unaffected by switch failure.
A plastic housing protects all the electronic components in the A3000. Solid state and integrated circuit electonics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards. Dwyer Photohelic A3000 switchgauges can be wired for high-latching, low latching or a combination of both.
