Product Description

The DWYER Air Velocity Transmitter (model AVUL-3DB1) is an air velocity transmitter that outputs a 4 mA to 20 mA signal. It has an air velocity accuracy of +/-3% and operates over a temperature range of 32°F to 122°F, with a velocity range of 1,000 fpm to 400 fpm. This unit supports BACnet communication protocol and does not include a calibration certificate.

Frequently Asked Questions

What is the DWYER AVUL-3DB1 air velocity transmitter used for?

The DWYER AVUL-3DB1 air velocity transmitter measures and transmits air velocity in HVAC systems, cleanrooms, or industrial ventilation. It outputs a 4 mA to 20 mA signal and supports BACnet communication for building automation. Typical applications include monitoring duct airflow and environmental control.

What are the specifications of the DWYER AVUL-3DB1?

The DWYER AVUL-3DB1 has an air velocity accuracy of +/-3%, a velocity range of 1,000 fpm to 400 fpm, and operates from 32°F to 122°F. It outputs 4 mA to 20 mA, supports BACnet protocol, and does not include a calibration certificate. The manufacturer part number is AVUL-3DB1.

Where to buy the DWYER AVUL-3DB1 worldwide?
