DP1400X1U21F Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP1400X1U21F is a high-performance, cost-effective low differential pressure transducer designed for precise air pressure measurement in commercial HVAC and building automation environments. It senses differential or gauge static pressure in air and nonconducting gases, converting it into a stable, high-level analog output signal. It features a compact footprint and utilizes a premium dead-ended capacitive sensing element that requires minimal amplification, delivering strong accuracy and long-term stability.
