Dwyer Instruments A3000-00 Pressure Switch/Gage
The Dwyer Instruments A3000-00 is an industry-standard Photohelic pressure switch/gage designed for precise differential pressure control in critical HVACR environments. This 2-in-1 instrument integrates a time-proven Magnehelic gage with high-performance low/high pressure switches to monitor and regulate positive, negative, or differential pressures. Engineered for air and non-combustible gases, it provides a 0-0.25" w.c. range with a 4" dial face for high visibility. Each setpoint controls a DPDT relay, allowing for sophisticated interlocked deadband control of fans and dampers. The phototransistor-actuated switching ensures that the analog pressure gauge reading remains continuous and completely unaffected by switch operations. With a rugged aluminum case and 1/8" FNPT connections, this unit is built for reliable HVAC system pressure monitoring in clean rooms, fume exhaust systems, and fluidic control applications. The setpoint indicators are easily adjustable via external knobs, simplifying field calibration and system integration for technicians.
Key Benefits
- Dual-Function Integration: Combines a highly accurate DPDT relay pressure switch with a precise Magnehelic gage for streamlined installation.
- Interlock Capability: Relays can be interlocked to provide a variable deadband, ideal for automated industrial pressure control.
- High Repeatability: Features ±1% repeatability on switch setpoints and ±4% accuracy on the -00 model scale.
- Continuous Monitoring: The Photohelic switch/gage maintains continuous pressure indication even during power loss or switch actuation.
- Heavy-Duty Rating: Electrical contacts are rated for 10A at 120/240 VAC, supporting heavy-duty HVACR components.
Common Questions
Can the A3000-00 be mounted in any orientation?
For maximum accuracy, this model must be mounted with the diaphragm in a vertical position. Mounting at other angles can shift the zero point and affect the precision of the 0-0.25" w.c. range.
What media is compatible with this pressure switch?
The unit is designed specifically for dry air and non-combustible, non-corrosive gases. Avoid use with liquids or hazardous combustible gas mixtures.
How do I adjust the switch setpoints?
Setpoints are adjusted using the two knobs located on the front dial face. This allows for quick setpoint changes without removing the electrical enclosure or stopping system operation.
