Daikin-McQuay 300070571 Duct Pressure Transducer 24V AC/DC 0-5" WC

The Daikin-McQuay 300070571 is a duct-mounted differential pressure transducer designed for precise monitoring of air pressure in commercial HVAC systems. This versatile sensor operates on either 24V AC or 24V DC power, making it compatible with a wide range of building automation and control systems.

Key Features:

• Pressure range: 0 to 5 inches water column (WC) for low-pressure air measurement
• Dual voltage capability: 24V AC/DC operation for installation flexibility
• Duct-mount configuration for direct airstream monitoring
• Analog output signal for integration with building management systems
• Engineered specifically for Daikin-McQuay HVAC equipment

This pressure transducer is commonly used to monitor filter status, measure airflow across coils, verify damper position, and maintain proper static pressure in air handling units and rooftop units. The 0-5" WC range makes it ideal for measuring the low differential pressures typical in HVAC ductwork applications. The sensor converts pressure measurements into an electrical signal that can be read by DDC controllers and building automation systems for real-time system monitoring and optimization.
