( Brand: Dwyer Instruments ), ( Manufacturer Part Number: A3000-0 ), ( Part Type: Pressure Switch )
The Dwyer A3000-0 Pressure Gauge is a versatile and reliable instrument designed for measuring differential pressure within a range of 0 to 0.5 PSI (Pounds per Square Inch). This pressure gage is a part of Dwyer's Photohelic series, which is renowned for its accuracy and durability.
The A3000-0 Pressure Gauge features a large, easy-to-read dial with a high contrast scale, ensuring that readings are clear and easily interpretable, even in low light conditions. The dial is protected by a polished, 316L stainless steel case, which offers excellent resistance to corrosion and ensures long-term performance in harsh environments.
The pressure gage is equipped with a Photohelic diaphragm, which is a light-sensitive device that converts mechanical pressure into an electrical signal. This technology provides excellent sensitivity and stability, ensuring consistent and precise readings. The gage also includes a built-in differential switch, which allows for easy integration into control systems and provides a switch output for alarm or shutoff purposes.
The A3000-0 Pressure Gauge is designed for easy installation and maintenance. It comes with NPT (National Pipe Thread) fittings and can be mounted in various orientations, providing flexibility in installation. The gage is also equipped with a drain valve, which allows for easy purging of air and moisture, ensuring accurate readings and preventing damage to the instrument.
In conclusion, the Dwyer A3000-0 Pressure Gauge is a high-quality and reliable instrument for measuring differential pressure within the 0 to 0.5 PSI range. Its large, easy-to-read dial, durable stainless steel case, and Photohelic diaphragm technology ensure accurate and consistent readings, while its built-in differential switch and easy installation features make it a practical choice for a wide range of applications.
Pros of buying a A3000-0 pressure gage 0-0.5 Dwyer differential switch photohelic w.c:1. High precision: The photohelic technology used in this pressure gage ensures high accuracy and reliability in measuring pressure.
2. Durable construction: The gage is made of high-quality materials, including a stainless steel body, which makes it resistant to corrosion and damage.
3. Wide operating temperature range: The pressure gage can operate in temperatures ranging from -40 C to 85 C, making it suitable for use in various industrial applications.
4. Easy to read: The large, easy-to-read dial and clear markings make it simple to monitor pressure levels.
Cons of buying a A3000-0 pressure gage 0-0.5 Dwyer differential switch photohelic w.c:1. Cost: The price of this pressure gage is relatively high compared to other pressure gages in the market.
2. Complexity: The differential switch feature may make the gage more complex to use for those who are not familiar with it.
3. Limited range: The pressure range of this gage is only 0-0.5, which may not be sufficient for applications requiring a wider range.
Conclusion:The A3000-0 pressure gage 0-0.5 Dwyer differential switch photohelic w.c is a high-quality, durable pressure gage that offers accurate and reliable pressure measurements. However, its high cost and limited pressure range may make it less suitable for some applications. If you require a high-precision pressure gage with a wide operating temperature range and can afford the price, then this gage is a good option.
Recommendation:If you are looking for a pressure gage with a wider pressure range and a lower price point, you may want to consider other options in the market. However, if you need a high-precision pressure gage for industrial applications and can afford the price, the A3000-0 pressure gage 0-0.5 Dwyer differential switch photohelic w.c is a reliable and durable option.
Easy to adjust set point indicators are controlled by knobs located on the gage face. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. The resulting photo transistor signal is electronically amplified to actuate its DPT slave relay and switching occurs. Relays are DE energized when gage pointer is to the left of respective set points relays are energized as pointer passes to the right of set points.
The photohelic gage measures and controls positive, negative or differential pressures of air and compatible gases. Solid state and integrated circuit electronics are on glass epoxy printed circuit boards and self extinguishing terminal boards for the series a3000 only. Standard model two photo transistor actuated circuits and two DPT relays permit both high and low alarms or limit controls.
Single pressure 36000s model's measure to 6000 pig 413 bar with a 9000 pig 620 bar rating mm w. Loss of electrical power or loss of pressure provide fail safe protection. 7 bar with options to when pressure changes, reaching either set point pressure, the infrared light to the limiting photo transistor is cut off by the helix driven light shutter. Two photo transistor actuated, DPT relays are included for low high limit control.
Relay transformer features a plastic housing protects all electronic components. 4 or individual set point headband is one pointer width less than 1 of full scale. Dead band between make and break is 1 of full scale or less.
Up to 30 psi 21 bar single positive pressure to 6000 pig 413 bar. Standard model's are rated to 25 pig 1.
