Product Overview
MAMAC Systems A-520-1-A-1 Static Pressure Probe
The MAMAC Systems A-520-1-A-1 is a 4-inch aluminum static pressure probe used to collect a duct-pressure signal from an air handler, plenum, duct, or similar HVAC assembly. Its two opposing pressure openings are designed to counteract airflow-related pressure effects, while the 1/4-inch brass hose barb provides the tubing connection to a compatible pressure transducer or switch.

FAQs:
Q: What is the MAMAC Systems A-520-1-A-1 static pressure probe used for?
A: The MAMAC Systems A-520-1-A-1 collects a static-pressure signal from HVAC ductwork, a plenum, an air handler, or similar equipment. It connects by tubing to a compatible pressure transducer or pressure switch, which uses the pressure signal for monitoring or control.
Q: What configuration does part number A-520-1-A-1 identify?
A: Part number A-520-1-A-1 identifies a 4-inch/100 mm A-520 probe made from aluminum and equipped with a 1/4-inch brass hose barb. In the code, the first “1” denotes probe length, “A” denotes aluminum, and the last “1” denotes the hose-barb connector.
Q: Is the A-520-1-A-1 the 4-inch or 8-inch MAMAC pressure probe?
A: The A-520-1-A-1 is the 4-inch/100 mm aluminum version. The A-520 family also includes an 8-inch/200 mm length, but that version has a different configuration code and should not be considered interchangeable without confirming the required probe length.
Q: How does the MAMAC A-520-1-A-1 reduce airflow-related pressure error?
A: The A-520-1-A-1 uses two sensing openings positioned opposite one another so that pressure effects created as air crosses one opening are countered by the effect at the second opening. This arrangement is intended to provide a more stable static-pressure pickup than a single opening exposed to moving duct air.
Q: How can I confirm that A-520-1-A-1 is the correct replacement pressure probe?
A: Confirm that the existing part or equipment documentation calls for MAMAC Systems A-520-1-A-1 and requires a 4-inch aluminum probe with a 1/4-inch hose-barb connection. Also verify the available insertion depth, mounting-flange arrangement, tubing size, application conditions, and requirements of the connected pressure transducer or switch.
