Dwyer Instruments A3000-100CM

Photohelic Pressure Switch/Gage Range 0-100 cm w.c

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).

Industrial-Grade Performance

Constructed with a die-cast aluminum case and polycarbonate window, the A3000-100CM is engineered for use in tough industrial settings. The IP54 front-panel enclosure, repeatability of 1% full scale, and accuracy of 2% ensure highly reliable results, even in demanding filter, fan, or blower monitoring scenarios.

Versatile Switch & Gauge Functionality

Featuring two adjustable dual SPDT snap switches and an analog display with status indicators, this Photohelic gauge provides quick response times with <100 ms switch delay. The gauge is mechanical and requires no power, while the switch activation is powered separately for enhanced safety and convenience.

Effortless Installation & Use

The pressure switch gauge supports both flush and surface mounting with provided hardware and accessories. The exterior front knobs allow for straightforward set point adjustments, and clear dial markings aid easy reading. Its standard 4" size fits most panel configurations.

FAQ's of Dwyer A3000-100CM Photohelic Pressure Switch Gauge Range 0-100 cm w.c.:

Q: How is the Dwyer A3000-100CM Photohelic Pressure Switch Gauge typically installed?

A: The A3000-100CM can be flush or surface mounted using the included mounting bracket, panel gasket, and hardware. It has a 4-inch diameter case suitable for standard panel cutouts. Installation is straightforward, and the instruction manual provides step-by-step guidance.

Q: What types of media can the A3000-100CM measure?

A: The gauge is designed to measure the pressure of air and non-corrosive gases, making it ideal for HVAC, filter monitoring, duct static pressure, and blower applications. The materials, including silicone rubber seals and an aluminum case, ensure compatibility with these media.

Q: When are the adjustable SPDT snap switches activated, and how are setpoints selected?

A: The two SPDT snap switches activate when the monitored pressure crosses the user-selected setpoints. Setpoints can be easily adjusted from the front external knobs without opening the enclosure, providing convenience and precise control.

Q: Where can I view the current pressure and switch status?

A: The current pressure is displayed on the large 4-inch analog dial, which features a white aluminum background with black markings. Switch status indicators are also present on the front for immediate visual reference.

Q: What are the key benefits of using this Photohelic gauge in industrial applications?

A: The A3000-100CM provides highly accurate (2% FS) pressure measurement, fast (<100 ms) switching, and long-term repeatability (1% FS). Its robust construction, flexible mounting, and ability to operate in temperatures from -7C to 60C ensure reliable performance in diverse environments.

Q: Does the gauge require an external power supply for operation?

A: No external power is needed for gauge (pressure) operation, as it is purely mechanical. However, electrical power is required for the switch functions, with a rating of up to 10A at 120/240 VAC.
