Photohelic Pressure Switch/Gage Range 0-.50" w.c./500-2800 FPM

PhotohelicSwitch/Gages Function As Versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelicgage design. The Photohelicswitch/gage measures and controls positive, negative or Differential Pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width - less than 1% of full scale. Set points can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25" (0-6 mm) w.c. up to 30 psi (21 bar); single positive pressure to 6000 psig (413 bar).

Reliable Air Pressure Monitoring for Industrial Applications

Engineered for air velocity and low-pressure gas measurement, the Dwyer A3000-0AV excels in demanding environments such as HVAC systems, process control rooms, and industrial air monitoring setups. Its die-cast aluminum case and clear acrylic lens ensure robust protection and lasting clarity, while its photoelectric control guarantees reliable and automated switching according to adjustable pressure thresholds.

Flexible Installation and User-Friendly Operation

With mounting options for both flush and surface setups, the A3000-0AV is designed for easy integration into control panels. The external front zero adjustment streamlines recalibration, while screw terminal electrical connections simplify wiring. The 4-inch (102 mm) case diameter provides a large, readable display, and included accessories make installation straightforward for professionals.

FAQs of Dwyer A3000-0AV Photohelic Pressure Switch Gauge Range 0-.50 Inch w.c./500-2800 FPM:

Q: How is the Dwyer A3000-0AV typically installed in industrial settings?

A: The A3000-0AV is designed for vertical orientation and can be flush- or surface-mounted, allowing flexible integration into control panels or equipment housings. Mounting hardware and installation instructions are provided to facilitate setup.

Q: What ranges of air velocity and pressure can this gauge measure?

A: This gauge accurately measures low differential air and non-corrosive gas pressures within 0-0.50 Inch w.c., corresponding to 500-2800 feet per minute (FPM) of air velocity, making it suitable for typical HVAC and air monitoring applications.

Q: When should the zero point be adjusted and how is it done?

A: Zero point adjustment should be checked during initial installation and periodically for recalibration, especially if the gauge has undergone relocation or mechanical shocks. The external front adjustment knob allows for quick and convenient zeroing without removing the device from its mount.

Q: Where is this photohelic pressure switch gauge most beneficial?

A: The gauge is ideal for HVAC filter monitoring, air velocity measurements, air flow indication, and automated process control in industrial and commercial facilities where precise and rapid pressure changes must be reliably detected and acted upon.

Q: What benefits does the photoelectric switching offer in process control?

A: Photoelectric switching ensures fast (sub-second) and reliable operation of the dual SPDT relays, enabling immediate signaling or control in air handling, filtration monitoring, and safety shutdown systems, enhancing overall automation and protection.

Q: How do the dual SPDT switches enhance the units usage?

A: The two independent SPDT (Single Pole, Double Throw) relays provide flexibility in control strategies, allowing simultaneous activation of alarms, fans, or other equipment when pressure thresholds are crossed, thereby improving system responsiveness and safety.
