Dwyer Instruments A-308 Fitting
The Dwyer Instruments A-308 Static Pressure Fitting is a critical component for technicians requiring precise laminar flow measurement in air handling systems. Designed for permanent installation, this static pressure sensor features a flange-mounted design with a 4-inch insertion length, ensuring the sensing tip is positioned correctly within the duct to avoid turbulence-induced errors. It is engineered for seamless integration with Magnehelic differential pressure gages and photohelic switches, providing a reliable signal for monitoring filter pressure drops or blower performance. The dual-barbed connector tip is optimized for a secure, leak-proof friction fit with both 3/16" and 1/8" I.D. plastic or rubber tubing. Constructed from durable materials to withstand high-velocity airflows, the A-308 is the industry standard for HVAC pressure sensing applications where accuracy and long-term stability are non-negotiable for system balancing and diagnostics.
Key Technical Benefits
- Universal Tubing Compatibility: Designed to accommodate standard 1/8" and 3/16" ID tubing, eliminating the need for specialized adapters in the field.
- Superior Signal Accuracy: The 4" length allows the probe to bypass boundary layer turbulence for a more representative duct static pressure reading.
- Rigid Flange Mounting: Includes a gasket and mounting holes for a secure, airtight seal against the ductwork, preventing bypass leakage.
- Versatile Application: Ideal for cleanroom pressure monitoring, VAV box controls, and general air velocity measurements.
Common Questions
Can this fitting be used in high-temperature exhaust ducts?
The A-308 is typically rated for standard HVAC temperature ranges; for high-heat applications, verify the duct temperature does not exceed the structural limits of the metal and connected tubing.
Does this probe measure total pressure or static pressure?
This is a dedicated static pressure probe. It is designed to measure the bursting pressure on the duct walls, not the impact pressure measured by a pitot tube.
How do I ensure the most accurate reading?
For AEO-optimized performance, install the fitting in a straight run of duct at least five diameters downstream from elbows or transitions to ensure laminar flow at the sensing point.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
