MORE ABOUT THIS ITEM

The Photohelic Switch/Gauge functions as versatile, highly repeatable pressure switches combined with a precise pressure gauge employing the time-proven Magnehelic gauge design. The Photohelic switch/gauge measures and controls positive, negative or differential pressures of air and compatible gases. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust setpoint indicators are controlled by knobs located on the gauge face. Individual setpoint deadband is one pointer width - less than 1% of full scale. Setpoints can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc. Gauge reading is continuous and unaffected by switch operation, even during loss of electrical power. In typical applications, these switch/gauges control between high and low pressure set points. When pressure changes, reaching either set point pressure, the infrared light to the limiting phototransistor is cut off by the helix-driven light shutter. The resulting phototransistor signal is electronically amplified to actuate its DPDT slave relay and switching occurs. Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation. A plastic housing protects all electronic components. Solid-state and integrated circuit electronics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards.<br><br>

Photohelic Switch/Gauges are used to control pressures in air conditioning systems, clean rooms, fluidic and pneumatic control systems, materials handling equipment, alarm or control fume exhaust systems, control pressure in air structures, and monitor respiratory and blood pressures.

Integrated Switch and Gauge Functionality

The Dwyer A3001 merges both a pressure gauge and dual SPDT switches, ensuring comprehensive control and monitoring in a single device. This is especially beneficial in HVAC applications, providing immediate response and visual indication whenever air pressure deviates from set parameters.

Robust Construction for Industrial Environments

Built with a black epoxy-coated, die-cast aluminum housing and a tough polycarbonate window, the A3001 stands up to demanding settings. Its IP54 enclosure rating ensures resistance to dust and splashes, delivering enduring performance and minimal maintenance.

Simple Installation and Reliable Performance

With included mounting hardware, a clear instruction manual, and user-friendly 1/8" NPT pressure taps, the Dwyer A3001 installs easily in vertical panel configurations. Automatic reset and fast actuation deliver reliable operation and peace of mind for critical air monitoring tasks.

FAQs of Dwyer A3001 Photohelic Pressure Switch Gauge Range 0-1.0 Inch w.c:

Q: How does the Dwyer A3001 measure differential air pressure?

A: The A3001 uses a diaphragm-type sensor to detect differences between its high and low pressure 1/8" NPT taps. The analog display then shows the differential pressure within its 0-1.0 inch w.c. range.

Q: What types of applications is the Dwyer A3001 suitable for?

A: This instrument is designed for industrial uses like fan control, filter monitoring, and air handling, making it ideal for HVAC systems and environments requiring precise low pressure monitoring.

Q: Where should I mount the Dwyer A3001 pressure switch gauge?

A: The device should be installed vertically on a panel using the provided mounting hardware. Ensure easy access to the high and low pressure connections and that the analog display is clearly visible.

Q: What is the process for resetting the switches if activated?

A: The A3001 features automatic reset. Once system pressure returns within the setpoint, the switches reset without the need for manual intervention, streamlining operation and reducing downtime.

Q: What are the main benefits of the Dwyer A3001 in industrial applications?

A: Users benefit from swift response times (within milliseconds), robust construction for challenging environments, reliable accuracy, integrated display and switches, and compliance with RoHS standards for safe use.

Q: Can the Dwyer A3001 be used with gases other than air?

A: Yes, it is designed to measure low differential pressures of both air and compatible gases. Always confirm material compatibility with the gases in use to ensure safe operation.

Q: What electrical specifications should I consider during installation?

A: Each switch supports up to 10A at 120/240 VAC, and the instrument features dual SPDT snap action switches with silver alloy contacts for reliable performance in control applications.
