Johnson Controls DP1402X5U21D Differential Pressure Transmitter WC - 0-2.5 4-20mA

The Johnson Controls DP1402X5U21D is a differential pressure transmitter designed for precise monitoring and control of air pressure in HVAC systems. This transmitter measures differential pressure ranges from 0 to 2.5 inches of water column (WC) and outputs a standard 4-20 mA analog signal for integration with building automation and control systems.

Key Features:

• Differential pressure measurement range: 0 to 2.5 inches water column
• 4-20 mA output signal for reliable communication with control systems
• Accurate pressure sensing for critical HVAC applications
• Designed for monitoring filter status, airflow, and static pressure
• Durable construction for commercial and industrial environments
• Compatible with Johnson Controls building automation systems

This differential pressure transmitter is ideal for applications including air filter monitoring, cleanroom pressure control, building pressurization, and VAV system monitoring. The 4-20 mA output provides a linear signal proportional to the measured pressure, enabling precise control and easy integration with PLCs, DDC controllers, and energy management systems.
