DP140001U11D Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP140001U11D is a cost-competitive, high-performance 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 analog output signal. Utilizing a dead-ended capacitive sensing element, the unit requires minimal amplification and ensures long-term reliability and accurate operation.
