DP1400X5U21D Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP1400X5U21D is a high-performance low differential pressure transducer designed for precise and reliable air pressure measurement in commercial HVAC and building automation systems. It utilizes a dead-ended capacitive sensing element that requires minimal amplification to sense differential or gauge static pressure in air and nonconducting gases, converting the measurement into a stable analog output signal.
