The probe measures airflow velocity across the duct cross-section by sampling multiple points simultaneously, producing an averaged pressure signal that reflects actual flow conditions. It is rated for velocity ranges of 400 to 5,000 feet per minute (FPM) with an accuracy of 5 percent, and it handles air temperatures up to 120 degrees F. This kit ships without an actuator or differential pressure transmitter, making it suitable for installations where those components are already specified or procured separately. Licensed HVAC controls technicians and mechanical contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe RAA-8-X is intended for round duct or round damper installations with an 8-inch diameter. Typical applications include air handling unit discharge sections, VAV system branch ducts, outdoor air intake measurement stations, and laboratory or cleanroom airflow monitoring points. The center averaging design is well suited to commercial ventilation systems where single-point pitot measurements would produce unreliable readings due to non-uniform velocity profiles. Because no actuator or differential pressure transmitter is included, the installing contractor must supply those components to complete the airflow measurement or control assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCenter averaging multi-point sensing delivers a representative mean velocity pressure across the full duct cross-section\u003c\/li\u003e\n  \u003cli\u003eVelocity range of 400 to 5,000 FPM suits a wide variety of commercial HVAC supply and return applications\u003c\/li\u003e\n  \u003cli\u003eAccuracy rating of 5 percent provides reliable flow data for controls integration and balancing work\u003c\/li\u003e\n  \u003cli\u003eRated for air temperatures up to 120 degrees F, compatible with standard supply and return air conditions\u003c\/li\u003e\n  \u003cli\u003e8-inch round damper configuration allows direct installation into standard round ductwork\u003c\/li\u003e\n  \u003cli\u003eSold without actuator or differential pressure transmitter for flexible component sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flow measurement component for round duct and damper assemblies with an 8-inch diameter, intended for use in commercial HVAC air distribution and ventilation control systems where a separate actuator and differential pressure transmitter will be field-supplied.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC controls technician or mechanical contractor familiar with airflow measurement stations and duct penetration requirements. Power down and de-energize all associated air handling equipment and control circuits before beginning installation. Locate the probe in a duct section with adequate straight-run upstream and downstream to minimize turbulence and ensure accurate velocity averaging. Connect the high and low pressure ports to a separately procured differential pressure transmitter following the transmitter manufacturer's piping instructions; do not obstruct or cap either port.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Round Air Flow Station\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVelocity Range\u003c\/strong\u003e: 400 to 5,000 FPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 5 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Air Temperature\u003c\/strong\u003e: 120 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDifferential Pressure Transmitter Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JOHNSON CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RAA-8-X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JOHNSON CONTROLS","offers":[{"title":"Default Title","offer_id":51284050837810,"sku":"RAA08X","price":107.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279118.jpg?v=1781067183","url":"https:\/\/voomisupply.com\/products\/johnson-controls-raa-8-x-flow-probe-kit-round-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
