Johnson Controls DP140005U21D Transducer

The Johnson Controls DP140005U21D is a high-precision low differential pressure transducer engineered for critical airflow monitoring in HVAC and building automation systems. With a 0-5" wc pressure range and unidirectional sensing, this unit is optimized for static pressure control and VAV applications. It features a robust IP67-rated housing, ensuring reliable performance in demanding environments prone to dust and moisture. The 4-20mA output signal provides a linear interface for integration with standard controllers, while the 1/4" push-on barb fitting facilitates secure pneumatic connections. Specifically designed to maintain a plus/minus 0.5% accuracy, it ensures tight tolerance control for air handlers and cleanroom environments. This model serves as the direct replacement for DPT2641-005D, offering a seamless mechanical and electrical retrofit without the need for additional mounting hardware or signal conditioning adjustments.

• High-Accuracy Sensing: Rated at +/- 0.5% FS accuracy to ensure stable reading for critical air handling sequences.
• Environmental Protection: The IP67-rated housing protects internal circuitry from liquid ingress and particulate contamination.
• Drop-In Compatibility: Engineered as a field-ready DPT2641-005D replacement to minimize labor during system maintenance.
• Standardized Output: The 4-20mA signal maintains long-distance transmission integrity even in high-interference mechanical rooms.

Is the DP140005U21D suitable for outdoor installations?
Yes, the IP67-rated housing provides the necessary protection against environmental elements, though shielding from direct sunlight is recommended.

Can this transducer monitor bidirectional airflow?
No, this specific model is a unidirectional 0-5" wc unit. For applications requiring negative and positive pressure sensing, a bidirectional configuration is necessary.

What process connections are required for installation?
This unit utilizes 1/4" push-on barb fittings, compatible with standard flexible pneumatic tubing used in most HVACR control circuits.
