Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic gage design. The Photohelic switch/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).

Accurate Differential Pressure Measurement

Engineered for pinpoint accuracy, the Photohelic Pressure Switch Gauge achieves 2% of full-scale precision in measuring differential pressures from 0 to 10 mm w.c. Suitable for low air and non-corrosive gases, it supports enhanced system safety and efficiency with reliable readings.

Robust Industrial Build with Easy Installation

Housed in a matte black die-cast aluminum case topped with a clear polycarbonate face, the gauge withstands industrial environments. The device comes with both flush and surface mount options, mounting hardware, and features a compact 4-inch (101.6 mm) diameter for versatile placement.

Simple Set Point Adjustment and Operation

This unit provides straightforward external set point adjustment via accessible knobs on the front panel. Users can easily configure activation points without internal access, ensuring quick process calibration and minimal downtime.

FAQs of Dwyer A3000-10MM Photohelic Pressure Switch Gauge Range 0-10 mm w.c.:

Q: How do you adjust the set point on the Dwyer A3000-10MM Photohelic Pressure Switch Gauge?

A: Set point adjustment is accomplished using the external knobs located on the front panel. This design allows you to easily calibrate the pressure switch activation points without opening the enclosure, streamlining the configuration process.

Q: What environments is the Dwyer Photohelic Gauge suitable for?

A: This pressure gauge is ideal for industrial environments requiring monitoring of low air or non-corrosive gases. With its IP54 ingress protection and robust die-cast aluminum case, it operates reliably from 20 to 120F, making it suitable for varied conditions.

Q: When should you use a Photohelic Pressure Switch Gauge instead of a standard pressure gauge?

A: Use the Photohelic Pressure Switch Gauge when you need both monitoring and switching capabilities. It integrates precise analog display with SPDT relay outputs, allowing you to both observe pressure and automate control processes in HVAC, dust collection, and air handling systems.

Q: Where can the A3000-10MM Photohelic Gauge be installed?

A: The device is designed for versatile flush or surface mounting and comes with required hardware. It is suitable for installation in control panels, equipment enclosures, or directly on walls in industrial and laboratory settings.

Q: What types of pressure media can the gauge measure safely?

A: The Dwyer A3000-10MM is engineered to measure differential pressure of low air and non-corrosive gases. Its silicone rubber seals and polycarbonate components resist deterioration from typical industrial air applications.

Q: How does the factory calibration benefit the user?

A: Factory calibration ensures that the gauge delivers accurate readings right out of the box, reducing setup time and minimizing the risk of measurement errors, so users can trust the performance without extensive on-site calibration.

Q: What is the process for electrical connection during installation?

A: The device features a screw terminal strip for straightforward electrical connections, enabling quick wiring of the power supply and switch contacts to a 120/240 VAC source.
