Overview
The Johnson Controls DP140X25B11F is a low differential pressure transducer designed for precise and reliable pressure measurement in demanding HVAC and building automation systems. It senses differential or gauge static pressure in air and nonconducting gases, converting it into a stable analog voltage output signal. Utilizing a dead-ended capacitive sensing element, the unit requires minimal amplification and ensures long-term operational efficiency.
