Dwyer AVLV-1DB1-LCD Air Velocity Transmitter features a temperature range of 32 to 122°F (0 to 50°C) and an accuracy specified on the catalog page. It operates on a power requirement of 24 VDC ±20% or 24 VAC ±20%. With a fast response time of 4 s typical and 1 s at constant temperature, it offers selectable ranges of 100, 200, 300, and 400 FPM (0.5, 1, 1.5, 2 m/s). The NEMA 4X (IP66) rated enclosure ensures durability. Offering multiple electrical connections, including analog and communication options, it provides output signals of 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC. Zero and span adjustments are made with digital push buttons. Suitable for clean air and non-combustible, compatible gases, it may be equipped with a 5-digit LCD display. The flow direction must be parallel to the sensor tip for accurate readings. It can handle a maximum load resistance of 1100 Ω for current output and requires 1 kΩ minimum load resistance for voltage output. The device consumes a maximum of 60 mA of current and supports communication at various baud rates. It has a 1/2" NPS threaded electrical entry and can be used with a specified cable gland. With a device load of 1/8 unit load, consult the factory for wetted material options.
