Schneider Electric (Barber Colman) 2323-504 Pressure Transmitter

The Schneider Electric 2323-504 is a robust pneumatic differential pressure transmitter designed for precise measurement of static pressure or velocity pressure in HVAC air handling systems. This unit features a sensing range of 0 to 10 inches Water Column (W.C.) and provides a proportional 3 to 15 psi output signal to the pneumatic controller. Engineered for efficiency, the 2323-504 maintains a low air consumption rate of 29 scim. This model serves as the designated direct replacement for P-5217-7 and P-5217-8 series transmitters, though technicians must verify their specific range requirements during fieldwork. Connectivity is managed through standard nipples for 1/4 inch O.D. tubing, with the critical exception of the LO and HI ports which necessitate 3/8 inch O.D. tubing for accurate pressure sensing. This transmitter is a staple for maintaining building automation system calibration and ensuring airflow setpoints are met with repeatablilty.

Key Technical Benefits

• Dual-Function Sensing: Capable of monitoring either differential or static pressure across fans, filters, and coils.
• P-5217 Legacy Compatibility: Directly replaces aging Barber Colman units to restore system accuracy without extensive piping modifications.
• Precise Signal Output: Delivers a consistent linear pneumatic response over the full 10-inch W.C. span.
• Optimized Air Consumption: Minimal 29 scim draw reduces the load on the instrument air compressor.
• Industrial Build Quality: High-tolerance construction ensures long-term stability in mechanical room environments.

Common Questions

Is the Schneider 2323-504 compatible with my existing P-5217 series bracket?
Yes, the 2323-504 is designed as a direct form-and-fit replacement for the P-5217-7 and P-5217-8, provided the 0-10" W.C. range matches your application.

What tubing sizes are required for the pressure ports?
While general connections use 1/4" O.D. tubing, the High and Low pressure ports require 3/8" O.D. tubing for proper seating and signal integrity.

Can this transmitter be used for duct static pressure control?
Specifically, yes. Its 0-10" W.C. range makes it ideal for high-pressure duct systems and variable volume air handling units.
