Overview
The Johnson Controls DP140X25B11D is a high-performance, cost-competitive 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, high-level analog output signal. Utilizing a dead-ended capacitive sensing element, the unit requires minimal amplification and ensures long-term reliability and accurate operation.
