DP1400X5U21F Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP1400X5U21F 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 nonconducting gases, converting it into a stable, proportional analog output signal. Utilizing trusted capacitive sensing technology, it delivers reliable performance, exceptional accuracy, and long-term stability with an excellent price-to-performance ratio.
