Schneider Electric (Barber Colman) 2323-500 Transmitter

The Schneider Electric (Barber Colman) 2323-500 is an industrial-grade differential or static pressure transmitter designed for precise monitoring across fans, coils, and filters. This one-pipe pneumatic device effectively senses pressure variations and transmits a 3 to 15 psig signal to receiver-controllers or pressure switches. Featuring a calibrated range W.C. 0 to 3 inches, it utilizes a ball-in-seat pneumatic feedback mechanism to maintain technical linearity and responsiveness even in demanding mechanical environments. The 2323-500 operates with a steady 29 scim air consumption and is engineered for surface mounting via integrated mounting ears. For pneumatic line integration, the unit utilizes barbed nipples compatible with 1/4 inch O.D. tubing, though the specific LO and HI ports require 3/8 inch O.D. tubing for proper impulse line connection. As a veteran-preferred pneumatic pressure transmitter, it serves as the direct replacement for P-5217-6 and P-5215-9 models, though field technicians must verify the pressure range during the swap-out process to ensure control loop stability.

• Broad Compatibility: Functions as a drop-in replacement for legacy Barber Colman P-5217-6 and P-5215-9 pneumatic components.
• Precision Engineering: The ball-in-seat feedback design reduces hysteresis and ensures consistent 3-15 psig output.
• Simplified Calibration: Features a field-adjustable zero to allow for easy recalibration during routine system maintenance.
• Robust Mounting: Dual mounting ears facilitate strain-free installation on ductwork or flat equipment surfaces.
• Low Air Demand: Optimized for systems with limited compressor capacity, requiring only 29 scim.

Is the 2323-500 compatible with standard 1/4" pneumatic lines?
The main pneumatic nipples are barbed for 1/4" O.D. tubing, but the High (HI) and Low (LO) sensing ports are specifically sized for 3/8" O.D. tubing to accommodate standard sensing probes.

Does this unit require an external restrictor?
Yes, as a one-pipe pneumatic transmitter, a 40 scim external restrictor must be used in the supply line for the unit to generate a valid output signal.

Can this be used for both static and differential pressure?
Absolutely. This transmitter is designed to measure static pressure in a single duct or differential pressure across components like filter banks or heating coils.
