DP140005B21C Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP140005B21C is a high-performance, cost-effective low differential pressure transducer from the DP140 Series designed for precise air pressure measurement. It senses bidirectional differential or gauge static pressure in air and nonconducting gases, converting it into a stable analog output signal using a dead-ended capacitive sensing element.
