DP140001U21C Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP140001U21C is a low differential pressure transducer designed for precise and reliable air pressure measurement in demanding commercial HVAC and building automation systems. It senses differential or gauge static pressure in air and nonconducting gases, converting the measurement into a stable 4 mA to 20 mA analog output signal. Utilizing trusted premium capacitive sensing technology, it requires minimal amplification and ensures long-term operational stability.
