The Schneider Electric (Barber Colman) 2422-002 is a professional-grade 3-1/2 inch receiver gauge designed for constant monitoring in pneumatic HVAC control systems. Engineered for flush-mount installation within control panels or equipment enclosures, this gauge provides high-visibility tracking of variables such as temperature, humidity, and differential static pressure when integrated with a transmitter-receiver loop. It operates on a standard 3-15 PSI signal range, delivering precise diagnostic data for air handling units and VAV systems. Built with technical durability in mind, the 2422-002 features a zinc-plated steel case and a chrome-plated snap-out ring to ensure long-term reliability in mechanical rooms. The 1/8" MNPT center back air connection simplifies integration with existing pneumatic lines. This unit is a direct replacement for several legacy and industry-standard models, including the A252, A252-1, AKS-9022, AKS-9055, and AKS-9082, making it a versatile component for retrofitting older Barber Colman pneumatic systems. Key Benefits: Universal Compatibility: Serves as a direct functional equivalent for A252 and AKS-9022 series pneumatic gauges. Precise Monitoring: Calibrated for 3-15 PSI pneumatic signals, ideal for reading transmitter outputs for HVAC pressure monitoring. Rugged Construction: Features a zinc-plated steel housing capable of withstanding industrial environments and vibration. Complete Installation Kit: Includes the necessary mounting hardware and overlay kit for immediate flush-mount deployment. Enhanced Readability: Large 3-1/2" dial face allows for accurate at-a-glance inspections by maintenance technicians. Common Questions: What is the standard pressure range for this receiver gauge? The Schneider 2422-002 is designed for a standard 3 to 15 PSI pneumatic control signal, which typically correlates to a 0-100% scale for temperature or pressure transmitters. Can this gauge be used for hazardous location monitoring? This gauge is suitable for NEMA 1 locations and is frequently used in air ducts, filters, and fan monitoring. Always verify enclosure requirements for specific hazardous environments. What is the connection type for the 2422-002? It utilizes a 1/8 inch MNPT center back connection, which is the industry standard for pneumatic receiver-controllers and gauges.
