Dwyer Instruments A-301 Pressure Tip
The Dwyer Instruments A-301 Static Pressure Tip is an essential field component for technicians requiring precise differential pressure measurements in high-velocity ductwork. Engineered for permanent installation, this angled sensor features a 4-inch insertion depth designed to position the sensing orifice away from duct walls, effectively minimizing the measurement errors typically caused by air turbulence or aspiration. Constructed for durability, it integrates seamlessly with 1/4" metal tubing connections and is fully compatible with professional-grade instruments including Magnehelic gauges, manometers, and pressure switches.
Operating efficiently in air flow velocities reaching up to 12,000 FPM, the A-301 utilizes four radially drilled .040-inch holes to ensure a stable and accurate static pressure signal. This makes it a go-to choice for monitoring static pressure drop across industrial air filters, cooling coils, and blower stages. For a standard install, the unit mounts securely into a 3/8-inch hole in the duct. Whether you are balancing a commercial HVAC system or setting up long-term monitoring for a refrigerant coil, the A-301 pressure tip provides the reliable pneumatic interface needed for critical system diagnostics and control.
Key Benefits- High Velocity Stability: Rated for accurate performance in airflow environments up to 12,000 FPM.
- Reduced Turbulence Interference: Radially drilled sensing holes eliminate the impact of air impingement for a true static reading.
- Rugged Construction: Designed for permanent installation within demanding industrial and commercial duct systems.
- Universal Compatibility: Optimized for use with 1/4" metal tubing and standard Dwyer pressure controllers and transmitters.
What size hole is required for installing the A-301?
For most standard duct applications, the A-301 requires a 3/8" hole for the 4-inch insertion probe to pass through for a secure mount.
Can this be used for temporary testing?
While the A-301 is intended for permanent mounting via its flange, it can be used for spot checks; however, the A-303 model is often preferred for portable use due to its magnetic mounting.
Is the tip compatible with flexible plastic tubing?
This specific model is designed for 1/4" metal tubing connections. If you are using 3/16" ID flexible rubber or plastic tubing, ensure you have the appropriate adapter or consider the A-302 series which is tailored for barb-style connections.
