Johnson Controls DP140005U21D Differential Pressure Transmitter 0-5 in WC 4-20mA Output

The Johnson Controls DP140005U21D is a precision differential pressure transmitter designed for HVAC and building automation applications. This transmitter measures differential pressure ranges from 0 to 5 inches water column (in WC) and converts it to a standard 4-20mA analog output signal for integration with building management systems and control panels.

Key Features:

• Measurement range: 0-5 inches water column (in WC)
• Output signal: 4-20mA analog current loop
• Accuracy: ±0.5% of full scale for reliable measurements
• Ideal for monitoring air filter status, airflow, and static pressure
• Compatible with Johnson Controls and third-party building automation systems
• Rugged construction for long-term reliability in commercial environments

This differential pressure transmitter is commonly used for filter monitoring, duct static pressure measurement, and airflow verification in commercial HVAC systems. The 4-20mA output provides excellent noise immunity over long cable runs, making it suitable for integration with PLCs, DDC controllers, and energy management systems.
