DP140010U21D Johnson Controls Differential Pressure Transducer

Overview

The Johnson Controls DP140010U21D is a high-performance low differential pressure transducer designed to sense differential or gauge static pressure in air and nonconducting gases. Utilizing trusted capacitive sensing technology, it converts pressure differences into a proportional high-level analog output signal, offering an excellent price-to-performance ratio for typical commercial building automation and HVAC systems.

Features

• Premium dead-ended capacitive sensing element requires minimal amplification and ensures long-term stability.
• Built-in reverse wiring protection and internal regulation safeguard against electrical damage.
• Robust IP67-rated, wash-down capable housing protects internal circuitry from moisture and dust ingress.
• Fire-retardant case meeting UL 94 V-0 approvals ensures safety and compliance.
• Easy installation with integral mounting tabs and a standard 1/2-inch conduit fitting with a screw terminal block.
