Schneider Electric (Barber Colman) 2220-053 Temperature Transmitter

The Schneider Electric 2220-053 Room Temperature Transmitter is a robust pneumatic temperature sensor designed for precise HVAC automation control. Functioning as a high-performance proportional transmitter, this unit converts room ambient temperatures into a 3 to 15 psi pneumatic signal, ensuring seamless integration with legacy Barber Colman pneumatic system architectures. It serves as the direct engineered replacement for the TP2220-052 and TP2220-053 models, maintaining mechanical and functional continuity within commercial climate control environments. The assembly includes a required 1/4" x 3/16" reducer, a 6" length of plastic tubing, and a sturdy mounting plate for efficient field installation. Engineered for reliability in building management systems (BMS), the 2220-053 minimizes drift and provides a stable pneumatic control signal. Technicians can rely on this transmitter for accurate ambient temperature sensing in retrofits or system maintenance, ensuring the pneumatic loop operates within specified parameters without constant recalibration.

Key Benefits

• Direct Replacement: Simplifies inventory by replacing obsolete TP2220-052 and legacy Barber Colman transmitter models with a precise 3-15 psi output.
• Complete Install Kit: Includes the 1/4" to 3/16" reducer and mounting hardware, reducing the need for additional pneumatic fittings during installation.
• Linear Signal Accuracy: Delivers a consistent proportional signal essential for the stable operation of pneumatic dampers and valves in commercial HVAC systems.
• Durable Construction: Specifically designed to handle the demands of industrial environmental control for long-term service life.

Common Questions

How do I calibrate the 2220-053 pneumatic signal?
Calibration involves adjusting the output pressure to match the actual room temperature against the standard 3 to 15 psi scale. Use a calibrated thermometer and a precision pressure gauge at the test port to verify the 9 psi midpoint at the specified temperature setpoint.

Is this unit compatible with existing Barber Colman mounting brackets?
Yes, the 2220-053 is designed to fit the standard mounting footprints of the TP series. The included mounting plate provides additional flexibility for various wall-box configurations common in pneumatic automation.

Can this transmitter be used in high-humidity environments?
While designed for standard indoor room sensing, the internal pneumatic components are sensitive to moisture in the air supply. Ensure the control air system is equipped with a functional air dryer and filtration to prevent orifice clogging.
