DP140X25B21C Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP140X25B21C is a low differential pressure transducer designed to sense differential or gauge static pressure in air and nonconducting gases and convert it into a proportional analog output signal. It features a robust, compact design with a dead-ended capacitive sensing element that requires minimal amplification, providing reliable performance for building automation and HVAC systems.
