DPT2650-005D-AB Johnson Controls Pressure Transmitter

Overview

The Johnson Controls DPT2650-0R5D-AB is a low differential pressure transducer designed to accurately measure and indicate differential pressure in commercial HVAC and building automation systems. It senses low static and differential pressures in air and nonconducting gases, converting the measurements into a stable output signal. Featuring a compact footprint and rugged design, this transducer delivers excellent accuracy and long-term stability for critical environmental control applications.
