Dwyer A3005 | Photohelic Pressure Switch/Gauge | 0-5 in w.c., 2 DPDT, 1/8 in NPT F

Name: Dwyer A3005 | Photohelic Pressure Switch/Gauge | 0-5 in w.c., 2 DPDT, 1/8 in NPT F
Brand: Dwyer
SKU: A3005
Availability: InStock

Part Number : A3005

Reading 0-5 in w.c. (0-0.18 psi), the Dwyer A3005 Photohelic switch/gauge (Series A3000) pairs a Magnehelic-design dial with two DPDT relays, giving both indication and low/high limit control for air and compatible gases.

0-5 in w.c. (0-0.18 psi) range on the A3005
Set point knobs on the gauge face; deadband under 1% of full scale per set point (A3005)
Set points can be interlocked for variable deadband, for fans and dampers (A3005)
Gauge reading continues during power loss (A3005)
Panel mount; dual side 1/8 in NPT female ports; 120 VAC; IP20 (A3005)

The Photohelic® switch/gage set point mechanism is visible when the bezel and front cover (which have set point knobs and a zero adjustment screw) are removed. Plastic cover made of clear polycarbonate.
Mounted on the helix and balancing counterweight are the gauge pointer and light shutter. Depending on the pressure exerted, the shutter travels through an optical limit switch slot to either mask or expose phototransistors to an integrated infrared light source.
Light shields phototransistors from bright external light sources while enabling unrestricted pointer movement. Additionally, it creates a tidy, "finished" look within.
Optical limit switches are favored for their longevity and dependability. They are individually aligned and attached directly to set pointers to provide perfect switching accuracy.Set point knobs are connected to a semi-flexible drive shaft.
To change the zero pressure measurement, the zero adjustment screw is connected to the screw in cover.
Electrical connections and electronic components are shielded by plastic enclosures.
The terminal board or polycarbonate connector self-extinguishes.
Circuit boards printed using glass epoxy for permanence and durability.
DPDT load relays with a latching feature allow for the greatest flexibility in application.
Electronic devices are intended to run on 120 volts at a frequency of 50/60 Hz, with a 10% voltage fluctuation. There are specific units available for different voltages.
Switch set pointers always display the switch settings.Operator damage to the set point mechanism is prevented by a spring-loaded friction clutch.
A 3-in-1 instrument reduces the need for many instruments with a single device, saving money, time, and inventory during installation.
A 1% full scale dead band and patented design allow for fast responsiveness to pressure changes, which eliminates noise and ensures seamless switching.
A large selection of models that can satisfy modest to extremely high pressure measuring requirements.
