Johnson Controls DP1402X5U11D Pressure Transducer

The Johnson Controls DP1402X5U11D Pressure Transducer is a precision-engineered low differential pressure transmitter designed for critical HVAC air monitoring and building automation. This unit features a 0-2.5" wc pressure range and provides a stable 0-5Vdc output signal, making it a reliable choice for monitoring static or differential pressure in air-handling systems. Built with a high-performance capacitive sensing element, it maintains 0.5% full-scale accuracy even in demanding environments. As the direct replacement for DPT2640-2R5D, this model simplifies retrofits with its standard 1/4" push-on barb fittings and IP67-rated housing, which ensures protection against moisture and dust infiltration. HVAC technicians will appreciate the unidirectional pressure sensing capabilities and the 24 VAC/VDC power flexibility. Whether you are managing cleanroom pressurization or VAV box flow, the DP1402X5U11D offers the performance and industrial-grade durability required for professional control sensor applications.

Key Benefits

• High Precision: Delivers +/- 0.5% accuracy (RSS) for tight control in sensitive air pressure applications.
• Rugged Design: The IP67-rated housing protects internal electronics from harsh mechanical room conditions.
• Easy Installation: Features 1/4" barb fittings and a standard 1/2" conduit electrical connection for fast field mounting.
• Drop-In Replacement: Specifically designed to replace legacy DPT2640-2R5D units without extensive re-piping.
• Signal Stability: Utilizes advanced dead-ended capacitive sensing to minimize signal drift and noise.

Common Questions Is the DP1402X5U11D compatible with 24VAC power? Yes, the unit supports both 24 VAC and 24 VDC excitation, providing flexibility for various controller power supplies. Can I use this for liquid pressure sensing? No, this transducer is specifically designed for dry air and non-ionic gas differential pressure measurements. Does the orientation affect the calibration? These units are factory-calibrated for vertical mounting. If installed horizontally, a minor zero-shift may occur, which can be corrected via the internal zero potentiometer. How do I wire the 0-5Vdc output? The terminal strip is accessed by a simple latch cover. Connect your excitation, common, and signal output leads following the diagram on the inside cover to prevent board damage.
