Schneider Electric (Barber Colman) 2422-001 Receiver Gauge

The Schneider Electric 2422-001 is a high-precision Barber Colman receiver gauge engineered for integration into pneumatic control systems. This 2-1/2" face unit provides clear visual feedback of pressure signals from remote transmitters, ensuring accurate monitoring of mechanical sequences. Known for its versatile application, the 2422-001 serves as a direct A251 replacement, fully compatible with legacy models including the A251-001 and A251-1. The assembly includes a comprehensive mounting and overlay kit, streamlining the installation process in control panels or field enclosures. This dual scale pressure gauge is a standard for technicians maintaining Barber Colman pneumatic loops, offering the durability required for industrial HVACR environments. By utilizing a high-visibility interface and standardized 1/8" NPT or terminal connections common to the series, it ensures seamless data interpretation for critical setpoint adjustments and system diagnostics. Professional-grade construction minimizes signal drift, maintaining the calibration integrity necessary for complex air-handling and central plant logic.

Key Benefits for Technicians
