MAMAC Systems A-520-1-A-1 Pressure Probe

The MAMAC Systems A-520-1-A-1 is a professional-grade 4" aluminum static pressure probe designed for precise aerodynamic measurements in ductwork, plenums, and air handlers. Engineered from high-strength 6061T-6 aluminum alloy, this probe features a dual orifice design specifically developed to eliminate airflow-induced errors. By positioning two 3/32" orifices vertically opposite each other, the sensor effectively cancels out velocity-driven suction, ensuring an accurate and stable static pressure signal even in high-velocity streams. This makes it an essential component for technicians monitoring clean room pressurization or diagnosing dirty filter conditions in sensitive HVAC environments.

Installation is streamlined via a 1.5" integrated mounting flange equipped with a neoprene gasket to prevent leakage at the insertion point. The unit includes an industry-standard 1/4" brass hose barb for a secure connection to transducers or manometers using PVC or copper tubing. With a maximum pressure rating of 10 PSIG and the ability to withstand temperatures up to 250°C, the A-520-1-A-1 duct probe provides the rugged reliability required for demanding industrial and commercial HVAC pressure monitoring applications.

• Dual Orifice Accuracy: Vertically opposed ports cancel out air velocity errors for a true static pressure reading.
• Industrial Construction: 6061T-6 aluminum alloy and brass fittings provide long-term durability in harsh duct environments.
• Zero-Leak Seal: Pre-installed neoprene gasket on the mounting flange ensures an airtight duct static pressure measurement.
• Universal Compatibility: Standard 1/4" hose barb fits most differential pressure transducers and HVAC switches.

Does the 4" probe length work for all duct sizes?
While the 4" probe is highly versatile for most standard ductwork, technicians should ensure the orifices are positioned away from the duct wall and clear of the boundary layer for the most accurate HVAC pressure sensor performance.

How do I ensure the probe is oriented correctly?
The orifices must be perpendicular to the direction of airflow. Use the mounting flange as a template to ensure the probe is inserted straight, allowing the dual orifice design to correctly cancel out velocity pressure.

Can this probe be used in high-temperature exhaust?
Yes, its aluminum construction and 250°C temperature rating allow it to function in high-heat applications where plastic probes would fail.
