DP1400X5B21D Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP1400X5B21D is a precision low differential pressure transducer designed for demanding HVAC and building automation systems. This bidirectional sensor monitors positive and negative pressures within a ±0.5 in. W.C. range, converting the measurement into a stable 4-20 mA analog output. It features a compact footprint and relies on a dead-ended capacitive sensing element that requires minimal amplification.
