DP140050U11C Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP140050U11C is a high-performance low differential pressure transducer designed for precise air pressure measurement in demanding HVAC and building automation systems. It senses unidirectional differential or gauge static pressure in air and non-conducting gases, converting it into a stable analog output signal. Utilizing trusted capacitive sensing technology, it offers an excellent price-to-performance ratio and reliable performance in environments where precise airflow and pressure monitoring are critical.
