Part Number: AVUL-5DB1-LCD
The Dwyer AVUL-5DB1-LCD is designed for higher-velocity duct applications, providing air velocity measurement from 1000 to 4000 FPM (5–20 m/s) with 5% of reading accuracy. Its BACnet MS/TP communication makes it suitable for direct integration with compatible building management systems and HVAC controllers.
The transmitter provides four field-selectable velocity ranges: 1000, 2000, 3000, or 4000 FPM (5, 10, 15, or 20 m/s). This flexibility allows the device to be configured for different supply, exhaust, and HVAC airflow requirements.
A durable NEMA 4X (IP66) enclosure protects the transmitter in mechanical rooms and plenum environments. It operates within 32 to 122°F (0–50°C) and supports 5–95% RH non-condensing humidity conditions.
The AVUL-5DB1-LCD has a response time of approximately 4 seconds under typical conditions and 1 second at constant temperature, making it suitable for AHU and fan-control applications. It operates on 24 VDC or 24 VAC with a maximum current consumption of 60 mA.
A built-in 5-digit LCD allows technicians to verify air velocity readings locally during installation, testing, and commissioning. This can simplify field verification before completing the BMS integration.
The transmitter's compact body is designed for mounting into a standard duct probe assembly. BTL and CE approvals support applicable BMS integration and electrical compliance requirements.
If a local display is not required, the Dwyer AVUL-5DB1 provides the same high-velocity measurement and BACnet communication configuration without the LCD.
