DP140X25U21F Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP140X25U21F is a 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 non-conducting gases, converting the measurement into a stable 4 to 20 mA analog output signal. Utilizing premium dead-ended capacitive sensing technology, it requires minimal amplification and ensures long-term reliability and operational stability.
