DP1400X5B21F Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP1400X5B21F is a high-performance low differential pressure transducer designed for precise measurement of differential or gauge static pressure in air and nonconducting gases. It utilizes trusted, premium capacitive sensing technology to convert low static pressures into a stable analog output signal, offering an excellent price-to-performance ratio for commercial building automation and HVAC environments.

Features

• Premium dead-ended capacitive sensing technology that requires minimal amplification and ensures long-term operational stability.
• Robust IP67-rated, gasket-sealed housing providing weatherproofing and wash-down capability for challenging mechanical environments.
• High-level reverse wiring protection and integrated internal voltage regulation to guard against field installation errors.
• Reduced installation costs via an easy-access screw terminal block, integrated mounting tabs, and face-located pressure connections.
• Fire-retardant enclosure approved to UL 94 V-0 safety standards, as well as CE and RoHS compliance.
